SUBJECT: August 2007 Water and Electric Operations Update


 

WATER UPDATE

 

Water Quality

Financial and Operations Update

  • Fiscal Year 2006-07 estimated Water Fund Financial Reserve balances as of June 30, 2007 are summarized in the following table:

 

 

BOU Water Production

 

Burbank Operable Unit (BOU) production was at 76.09% of plant capacity for June. This is an average flow rate (24/7) of 6,848 gallons per minute (gpm).  Plant production was held at half capacity for 10 days while some screen repairs were done in two of the Vapor Phase GAC (VPGAC) Units and the carbon was changed out in preparation for a virgin carbon performance test.  Six of the eight water wells were available for service, with five wells providing the required flow.  The pumps and motors of the two wells that are out of service are being repaired or replaced.  New power conductors, or wire, are being pulled through existing conduits for both wells.  The pumps should be ready for service by the middle of July.    

 

Environmental Protection Agency (EPA)

 

A signed design contract between ECO, the BOU O&M contractor, and MEGTEC, the design and construction contractor for the VPGAC carbon retention screen replacement project was in place December 15, 2006.  The final design package will include an updated construction cost estimate for the project.  Plans were submitted to BWP and were returned to MEGTEC for revision and correction.   EPA�s approval is the controlling feature in proceeding with this project.  We are working to get an expedited review and approval from the EPA. 

 

The EPA also requested a full scale test of utilizing virgin carbon in the VPGAC filter vessels and deleting on-site carbon regeneration.  A test began on June 16th and will have to run a minimum of 60 days or until the carbon is exhausted.  Lockheed Martin has agreed to bear the cost of all of this work.  In the meantime, the MEGTEC design will be completed so that a decision on the project alternative can be made as soon as possible.  The testing will delay the start of the project until possibly October.  Construction is projected to take 18 weeks and will likely be completed by the end of February 2008. The Treatment Plant will experience reduced operating capacity during project construction. There will be an increased need to purchase water from the Metropolitan Water District (MWD) during construction. However, the timing of the construction will now reduce the water volumes that will be purchased.  These additional water purchases from MWD will significantly impact WCAC expenses and may result in the use of a significant portion of the WCAC balance.

 

San Fernando Basin Groundwater Credits

 

Burbank, Glendale and Los Angeles are discussing the issue of an over statement of Import Return Groundwater Credits in the San Fernando Basin.  The discussion is centered on the calculation of the credits within the context of the 1979 Judgment that adjudicated the basin and is under the administration of the Upper Los Angeles River Area Watermaster.  Burbank and Glendale are in disagreement with the Watermaster as to the proper application of the terms of the Judgment to resolve the imbalance of ground water credits.  Los Angeles, Glendale and Burbank have continued to meet since January, and have tentatively reached an agreement with each other and the Watermaster.  Work on a final document for a 10-year program of interim replenishment and enhanced water storage in the San Fernando Basin was completed, has been accepted by the Watermaster and will be submitted to the Court after approval by all three City Councils.   

 

Chromium Contamination in the Groundwater

 

Drinking water in Burbank does not exceed 5 parts per billion (ppb) chromium by direction of the City Council.  This is achieved by blending the BOU produced water with MWD water to obtain the 5 ppb concentration.  Current Federal and State Maximum Contaminant Limits (MCL) are 100 ppb and 50 ppb, respectively.  Work has been underway for the last four years to develop a new limit for chromium. Work is being done by the National Toxicology Program (NTP) within the EPA.  Results of the study were released May 16, 2007.  The study concluded that Chromium VI is a carcinogen when ingested.  The study used high concentrations of chromium, the lowest being 5,000 ppb.  The promulgation of a Public Health Goal (PHG) [none currently in place] and a new MCL are the next steps and will come from the California Department of Health Services.   Water Industry speculation places the anticipated PHG between 3-30 ppb.  A PHG lower than 5 ppb, if adopted by the City Council, would limit Burbank�s current operations and increase reliance on imported MWD water, or require additional treatment for removal of Chromium.  Either alternative would significantly increase Burbank�s water costs. 

 

Water Supply and Conservation

 

Given the current drought conditions in the Colorado River Basin, this year�s minimal snow pack in the Northern California mountains, and the �temporary� shut down of the State Water Project export pumps, it was deemed prudent to intensify Burbank�s message of water conservation in June.  Burbank is currently well positioned for water resources to support regular use for this year.  Existing groundwater resources and the use of recycled water have offset a prior total dependence on water imported and treated by the Metropolitan Water district (MWD).  Roughly half of Burbank�s projected potable water use will be provided from MWD as treated water. However, MWD may yet call later this year for conservation and it would show good stewardship and a wise use of resource to begin now to further encourage conservation.  Past voluntary efforts in Burbank during drought conditions have yielded as much as a 20% reduction.  Burbank has also shifted potable use to the recycled water system as the recycled system has been developed.  Those parks, golf courses and businesses that utilize recycled water will not be affected by any conservation measures aimed at reduced landscape irrigation. 

 

Continued efforts to install water saving home and business fixtures, irrigation systems and California friendly gardens, along with the City�s plans to expand its use of recycled water through the approval and implementation of a new recycled water master plan, will help position the community in terms of efficiency and our ability to withstand prolonged drought conditions. The Council may wish to consider actions like ordinances to require retrofitting or upgrading of fixtures upon the sale of property or drought operations ordinances which might provide for enforcement of operating practices during a period of extended drought (both of these are included in the Sustainability Goals for consideration by Council.)

 

Capital Projects

  • Construction was completed on 580 lf of new 8-inch water main in Naomi St. from Olive Ave. to Oak St. 

  • Construction began and was completed on 240 lf of 12-inch recycled water main across Burbank Blvd. at Orchard Dr. and Parish Pl. in advance of the paving for the Burbank Blvd. beautification project.

  • Segments of the MWD San Fernando Tunnel were inspected on June 8, 2006 and August 22, 2006.  BWP�s Assistant General Manager of Water Systems participated in the inspection.  The tunnel appears fit for service.  MWD has reviewed the alternatives and now has a schedule for the tunnel cleanup.  Burbank is proceeding with construction of the B-6 pipeline and appurtenant facilities prior to MWD work in November 2007.  MWD will be ready to clean the tunnel in November and finalize their project construction after that.

Refer to the attached legislative reports.

 

ELECTRIC UPDATE

 

Safety

 

During Fiscal Year 2006/07, we had one lost time incident in the line section involving a Line Mechanic Apprentice, who has recently been returned to light duty.

Electric Reliability

 

There were three, 4 kV feeder outages in June. These outages interrupted service to 2,623 customers for a total of 216 minutes. 

 

Despite the power outages in June, BWP�s overall reliability continues to be strong. As of June 30, 2007, the system-wide average is 0.2161 outages per year, compared to an industry average of 1.2 outages per year. The average service availability is 99.9970%, exceeding the City goal of 99.99%. The average outage length is 74.01 minutes, compared with the industry average of 80 minutes.

 

The following table shows the system-wide reliability statistics for Fiscal Year 2006-07 through June 30, 2007, as compared to the same time period for Fiscal Year 2005-06:

  • Fiscal Year 2006-07 estimated Electric Fund Financial Reserve balances as of June 30, 2007 are summarized in the following table:

 

 

MPR Refinancing

 

In June of 2007, the Southern California  Public Power Authority (SCPPA) refinanced a portion of the Magnolia 2003-1 bonds at a significantly lower interest rate.  The refinancing resulted in an interest rate of 4.14%; the original 2003 bonds were at a rate of 5.00%.  The refinancing was completed at a very opportunistic time.  In recent decades, interest rates have only been lower a very small percentage of the time.  Over the life of the bonds, the reduced interest rate will result in a gross savings of $23.5 million, with a present value savings of approximately $14.5 million.   On an annual basis, the savings will be approximately $800,000.  Since, Burbank�s share of the debt service is 32.4 percent of the Magnolia 2003-1 bonds; BWP will have an annual reduction of debt service of approximately $260,000 through the year 2036.

 

Local Generation Operations Update 

 

Unit Status

  • Olive 1 and Olive 2 are in wet lay-up.

  • Lake One is unavailable.  Major maintenance is being performed to address service bulletins and compressor damage.  It is estimated the unit will be ready to return to service July 28, 2007.

  • The Landfill Microturbine Facility is operating normally and produced approximately 103,680 kilowatts of energy in June. 

  • The Magnolia Unit is on-line and available for normal service.

Magnolia Operations Update

 

Workforce Safety Statistics:

  • No loss time accidents for June, zero year-to-date. 

  • Zero reportable accidents for June, one year-to-date.

Performance Information:

  • Availability:  54.0% for June, 79.2% fiscal year-to date, 84.7% year-to-date.

  • Unit Capacity Factor (240 MW): 43.5% for June, 68.3% fiscal year-to-date, 72.0% year-to-date.

  • Fired Hours on the Combustion Turbine:  388.5  hours in June.

Actions Taken by Operating Agent:

  • One planned outage of 230 hours duration was started on June 8.  The main reasons for the planned outage were to upgrade the GE accessory module to allow on-line water wash of the Combustion Turbine Generator (CTG), to inspect the CTG first stage blades, and to replace the Steam Turbine Generator (STG) rotor position sensor probes.  Several other maintenance tasks were accomplished during the planned outage.

  • It became necessary to extend the outage by almost two days to complete the replacement and setup of the STG rotor position sensor probes.  Plant operation was restored on June 20.

  • The Plant tripped on June 20, when the �B� Fuel Gas Compressor tripped on a false high vibration signal.  Plant operation was restored on June 22, after reinstallation of the rebuilt �A� Fuel Gas Compressor Motor was finished.

  • The Plant tripped on June 26, when the �A� Fuel Gas Compressor Motor failed.  Plant operation was restored on June 27, after repairs to the �B� Fuel Gas Compressors were completed.

Renewable Energy Update

 

Utah Wind Development

 

Work on finalizing the power sales agreements between SCPPA and its members who are going to receive energy from the facility continued during the month.  It is currently expected that this agreement between SCPPA and the off-takers Burbank, Glendale, and LADWP will be completed in July 2007.  Burbank has a 10 MW interest in this resource.

 

Pacific Northwest Wind Development

 

During the month, negotiations continued with the developer of a wind facility located in the Pacific Northwest.  We received confirmation that their new corporate owner�s business model precludes the purchase of the physical facility by SCPPA.  This developer is now only interested in negotiating a power sales agreement.  Accordingly, SCPPA is examining how to proceed with this project.  As well, Burbank on its own has begun discussions with another developer for power from the region which may ultimately lead us to go with an alternative source. 

 

Imperial County Geothermal Development

 

SCPPA continues with preliminary planning work on a geothermal facility in Imperial County.  The in-service date is currently anticipated to be in late 2011, or early 2012.  Nine (9) MW in an initial phase would supply 6% of BWP energy requirements.  Energy would be delivered to BWP via the proposed Greenpath Transmission Project. 

 

Greenpath Transmission Project

 

Planning work continues on this project.  We�re in the early stages of planning a route that will result in the least impacts on the environment, critical wilderness areas, and existing urban development.  To that end, work is just beginning on the required environmental review of the proposed project, under both State and Federal law.  This lengthy and very public process will include preparation of the Environmental Impact Report (EIR), as mandated by the California Environmental Quality Act (CEQA) where LADWP will act as the lead agency, and an Environmental Impact Statement (EIS) as mandated by the U.S. National Environmental Protection Act, which the Bureau of Land Management and the U.S. Forest Service will be the Federal agencies jointly acting as lead agencies.

 

Generally, the route will connect a new electrical substation in Hesperia to the Devers II substation that will be built near Palm Springs.  However, no specific alignment of that route has been approved.  The project�s anticipated in-service date is late 2010, or early 2011.  Current plans are for 1200 MW transfer capability however, ultimately this may be increased to 1600 MW.

 

SCADA/EMS

 

BWP engineering staff is currently working with Siemens New Energy on an upgrade to the existing New Energy Scheduling System to improve participant use.

 

BWP engineering staff is currently working with Telvent to improve upon current system configuration.  This will provide for improved data storage, improved command response, and assist in data linking with the responder application.

 

Telecom

 

Engineering developed a fiber optic service proposal for Sohonet to connect their existing link at the Magnolia (MPP) Co-Locate room to the following addresses:

  • 2777 North Ontario St.

  • 2522 North Ontario St.

  • 1133 North Hollywood Way

Engineering developed a fiber optic service proposal for Disney to connect the following facilities:

  • Team Disney at 500 South Buena Vista St. to 3601 West Olive Ave. 

  • Disney ABC at 2300 Riverside Dr. to 3601 West Olive Ave.

Engineering generated and released two new job orders for the undergrounding of fiber optic cables related to the Olive Underground Project:

  • Re-route the fiber links between City Hall and the Public Works Yard.

  • Re-configure the Recycling Center termination equipment and splice cables straight through.

A final job order is being created to underground the fiber cables along Olive Ave. from Lake St. to Flower St.

 

BWP field personnel completed 4 fiber optic jobs to re-route fiber links affected by the Olive Ave. Underground Project.

 

BWP field personnel completed a fiber optic job for Warner Brothers to connect the �CW� at Warner Ranch to �The Switch� at 3400 Motor Ave. in Culver City.

 

Engineering released, and BWP field personnel completed fiber optic jobs for Warner to connect the following locations;

  • Warner Lot through Warner Station Power House to Ascent Media at 2130 North Hollywood Way.

  • Warner Bros Building 157 to Ascent Media at 2130 North Hollywood Way.

BWP Facility Improvements

 

Implement Automatic Reclosing of Distribution Circuits

 

Often, an object causes a short circuit on an overhead power line for only an instant (technical term: transient fault), and does not damage the line. For example, a branch may fall between two conductors, touching them only briefly; or a kite tail may instantly vaporize as soon as it touches two conductors. The utility industry has responded to these situations by using reclosers, which closes a line back in very soon after it has been short circuited.  If the cause of the short circuit is no longer present, the line stays in service; if the cause is still present, the line relays out soon enough to avoid damage to the line.

 

Re-closing is especially important for BWP's six, mostly-overhead 12,470-volt (12 kV) circuits, which serve two to three times as many customers than the older, 4,160-volt feeders.  BWP will add the re-closing feature to two, 12 kV distribution circuits (Keystone-6, Keystone-13) before August 31, 2007 and to 4 circuits (Hollywood Way-4, 5, 6, and 7) before January 2008. BWP is finalizing its reclosing procedures, which will assure that reclosing does not endanger electrical workers who may be working on these lines. BWP will meet and share the new procedures with the International Brotherhood of Electrical Workers (IBEW) before implementing.

 

4,160-Volt Distribution System- Impacts of heat wave and follow up action plan

 

After the July 2006 heat wave, the Energy Control Center (ECC) initially reported 32 distribution circuits showing overloads. BWP carefully reviewed the loading of those circuits and identified 12 distribution circuits that needed reconductoring with larger lines that can safely carry heavier currents:

  • Flower-3: Reconductor 5 spans of three-phase, 4,160-volt (4 kV) underground cable. (An underground span goes from one maintenance vault to the next.) Complete.

  • Naomi-17: Reconductor 15 spans of three-phase, 4 kV overhead conductor. (An overhead span goes from one pole to the next.). Engineering completed the job which was issued to the line crews in May. This reconductoring job originated from the Naomi-21 Feeder job and the re-routing/undergrounding of overhead conductors related to the old Buena Vista Library site project. This is necessary to improve the back-up between these circuits and other circuits in the area. Reconductoring is in progress and estimated to be completed by end of July 2007.

  • Burbank-8 (NEW JOB): Re-conductor 9 spans of overhead conductor. This job is an extension of the Naomi-17 reconductoring job and is necessary to improve back-up between Naomi-17 and Burbank-8. This project is estimated to be completed by August 15, 2007.

  • Naomi-21: Reconductor 5 overhead spans. Engineering completed, the job was issued to line crews in May. Reconductoring is in progress and expected to be completed by the end of July 2007.

  • Pacific-15: Reconductor 3 underground spans (from one maintenance vault to the next) of underground cable. Complete.

  • Pacific-17: Reconductor 3 underground spans. Complete.

  • Town-4: Reconductor 46 overhead spans. Complete.

  • Town-19:  Reconductor 13 underground spans. Complete.

  • Town-21: Reconductor 36 overhead spans. Complete.

  • Victory-1: Reconductor 69 overhead spans. Complete.

  • Victory-3: Reconductor 28 overhead spans. Complete. The line crew discovered that they needed to replace damaged underground cable from the riser pole to a nearby maintenance vault for Victory-3 and Victory-2. Complete.

  • Victory-7: Reconductor 66 overhead spans. Complete.

  • Victory-13: Reconductor 31 overhead spans. Complete.  Reconductor 5 spans of underground cable. Complete.

  • Victory 14: Reconductor 83 spans. Completed 67 spans of main circuit; in June crews will complete one branch circuit (16 spans) at Evergreen St., north of Burbank Blvd. Reconductor 5 spans (from one maintenance vault to the next) of underground cable. Complete.

  • Winona-11: Reconductor 4 spans of underground cable. Complete.

As of June 30, crews reconductored 29 miles of overhead conductor and approximately 2 miles of underground cable.  By August 15, 2007 all major feeder reconductoring jobs related to the July 2006 heat wave will be complete. Only the lateral overhead conductors of Victory-14 and Town-4 will remain and crews will continue to work on those along with other planned 12 kV conversion jobs.

 

The reconductoring work was not a part of the Fiscal Year 2006/07 CIP Budget as the need for it did not become apparent until after the July 2006 heat wave. When completed, this work will have cost $1.7 million ($1.1 million for labor/overhead and $600,000 for conductor, cable and other materials). The impact on the Fiscal Year 2006/07 CIP Budget led to delays in three budgeted capital projects: Olive-Valley No. 2, Replacement Burbank Station, and Olive Avenue Underground Utility District 1.

 

Substation power transformers serve a neighborhood, or a very large customer like a major studio. Even during the 2006 heat wave, all substation transformers were loaded well under their rated capacity because every substation has two or three substation transformers. If one of the substation transformers should fail during a heat wave, the remaining transformer(s) will be able to handle the other transformer�s load as well as its own with minimal overload.   Nevertheless, BWP believes it is prudent to assess the remaining useful life of its substation transformers so that it can replace them well in advance of a crisis situation. The average age of those station transformers is 45 years, with some as old as 66 years.

 

Doble Engineering Company is assessing 30 critical transformers, and are currently making visual inspections and analyzing available records. Analysis and review of maintenance records and past loading history of station transformers will continue through July, with the final report expected by the end of July.  (Other critical transformers will be reviewed next fiscal year.)

 

BWP Administration Building - Phase III Interior Remodel

 

Icon West, Inc. completed construction work in the basement-level of the Administration Building. Construction work has begun on the first floor (east wing), second floor (east and west wing) and third floor. The project completion date for the entire building remodel is January 2008.

 

BWP Service Center and Warehouse Project

 

BWP is negotiating a contract with McCormick Construction Company guided by the bridging documents by Kennard Design Group.  If BWP and McCormick agree on a first lump sum price, and terms and conditions, it would be scheduled for City Council approval by August 31, 2007. If not, BWP is prepared to re-bid the work. Construction is scheduled to begin in January 2008, with a target completion of July 2008.

 

The next phase will demolish the existing Warehouse and the Line Section field offices, and the covered storage and parking. This area will be converted to employee vehicle parking.  The next phase will also demolish the existing Water Maintenance Building along with the Guard House, and install landscaping and additional employee parking. A new Security Office of approximately 600 square feet will be constructed on Lake St. at the intersection of Palm Ave. that will control ingress/egress to the entire BWP campus. A vehicle wash rack will also be added. Completion of the aforementioned phases is anticipated for January 2009. The final phase of the project constructs a replacement Burbank Substation with a state-of-the-art GIS substation. The GIS substation will be built at the southwest corner of the campus on a footprint one-third the size of the existing Burbank Substation. All equipment will be removed from the existing substation, the site will be scraped and the area converted into a courtyard.  

 

Security Wall Construction

 

McClean & Schultz, Principal Architect, completed a structural review including engineering signatures/stamp on the drawings prepared by Bibb. Once the final construction documents are completed, a bid package will be assembled and submitted to Purchasing for the competitive bid process to hire a contractor. Work is anticipated to begin January 2008, and be completed in March 2008.

Communication Shop Relocation

 

Work has begun to provide a new home for the Communication Shop. McLean & Schultz completed and submitted the final construction documents and technical specification package. Remediation and removal work has been completed. Icon West will begin tenant improvement work on the Communication Shop in July 2007. The anticipated completion date for this work is December 2007. Communication Shop staff can then be relocated, allowing for the construction of the Replacement Service Center/Warehouse in January 2008. 

 

Electrical Distribution

 

Construct a New Olive-Valley #2 Line  

 

Olive Station Portion: Breakers are on the new equipment pads; disconnect switches have been mounted on the supporting structures. We need to build the structures and devices to terminate new underground cable from the newly installed duct system which is underway along Olive Ave. Engineering for relays and panel work is currently underway and will be issued to the field crews.

 

Olive Underground Portion: Duct and maintenance vault construction is underway along Olive Ave. and completed from the Olive and Lake intersection to the Olive and Victory intersection, and north and south of the intersection to the new riser pole. Duct work is 75% complete in the block between Lake St. and the west edge of the Olive Ave. Bridge. Work will be completed by July 31, and the final street paving is scheduled for August 10 and 11.

 

North-South Victory Portion: This work has not yet begun. The work calls for new insulators and reconductoring, but not pole replacement. This project was delayed to allocate field resources to complete the reconductoring jobs originated as a result of the July 2006 heat wave.

 

Five Points Underground Portion: Ducts and maintenance vaults installed at the time of the Five Points project.

 

East-West Victory Portion:  Construction of the overhead portion of this line along Victory Blvd., from the Costco area to Victory Blvd. and Fairview St. will include the replacement of 30 poles, upgrading 3,000 circuit feet of overhead conductor, adding new polymer insulators and changing the insulators from porcelain to polymer.  The poles and other material have been ordered, and locations of the new proposed poles are marked in the field. Construction of the overhead has been delayed to Fall 2007 in order to utilize the field crews on reconductoring jobs.

 

Valley Station Portion: The consultant, ORSA, completed the design for pads and underground power conduits for the extension of the ring bus at the Valley Switching Station. Bock Company completed the duct work inside the substation and through Ralph Foy Park.  They also completed all duct work required on Victory Blvd. up to Fairview and to the new riser pole. The final design for ground grid and equipment pads was completed and issued for construction.  All equipment pads, control/communication conduit work along with the ground grid work in the extended ring-bus area is completed. All breakers and disconnect switches are set on the pads and structures.  Most of the bus work is finished and the remaining bus work is to be completed by June 30, 2007. The remaining ground-grid, control/communication wiring work, and relay panel work is estimated to be completed by March 2008.

 

Replacement Burbank Station Project.

 

A contract was awarded to ABB Inc. in the amount of $17,247,260.  All major pieces of equipment with a long lead time have been ordered.  Construction of the duct system on the BWP campus started on April 23, 2007 and is on target for completion by July 16, 2007.  Duct work outside the BWP campus along Lake St. from the security gate to Magnolia Blvd., along Magnolia Blvd from Lake to Moss St. and the alley south of Magnolia Blvd. between Lake and Victory will start during the summer of 2007. All duct work will be completed by December 31, 2007, including all station getaways at Lake St. between Olive Ave. and Orange Grove Ave. The foundation and equipment pad construction will start in July 2007, and will continue until December 2007.  Major equipment delivery will take place in December 2007 and January 2008. The Station will be partially energized by June 2008.  Most of the 34,500-volt network will be transferred to the new station by June 30, 2009. All 4,160-volt load that is directly served from the Burbank Station will be transferred and de-energized, all station equipment physically removed, and the station demolished by June 30, 2010.

 

Compliance with NBC Master Plan - Planned Development 96-1

 

BWP staff provided comments to the Community Development Department regarding the compliance with Planned Development 96-1, expanding the parking under LADWP�s 230 kV high voltage lines near NBC, and the method of service for M. David Paul Development on the Catalina property.  Providing electric service for this development involved an extension of the 34,500-volt line (ducts and cable) from Willow St. along Fredrick St. to Alameda Ave., and along Alameda Ave. from Fredrick St. to Naomi St. This work was completed in March 2007. 

 

The new 34,500-volt line position at Naomi Station as well as a small amount of work at Capon Switching Station was completed in March 2007.  

 

On the Catalina site, two padmount switches and four padmount transformers will be required to transform power to utilization voltage for the parking structure and both office buildings.  Under the current BWP Rules and Regulations, M. David Paul will pay 100 percent of the cost of the work directly related to its service as aid-in-construction charges, and will also reimburse BWP its prorated share of system improvements completed since July 2001. On January 26, 2007, Krismar Construction Company, on behalf of M. David Paul, paid $1.2 million as a reimbursement for the system improvement for Phase-1, and paid $300,000 as a first installment of the direct cost of service.  Krismar Construction paid the second installment of $300,000 on April 10, 2007, and paid the remaining $455,000 June 30, 2007.  Phase-2 of the project is two to three years away.

 

Reliability of the Golden State Distributing Station

 

In most of BWP�s substations, BWP can restore power by making use of a direct connection to the station transfer bus, or by transferring load to other stations. These options are not available at the Golden State Substation, which experienced switchgear problems in 2005.  Working with its engineering consultant, Power Engineers Inc., BWP has found a way to make a direct connection between Golden State�s transfer bus and the power transformers, while also adding a substation capacitor bank. The City Council approved this work at its March 13, 2007 meeting. BWP has negotiated the price, terms and conditions of the agreement with ABB Inc. During negotiations ABB suggested we add disconnect switches to the direct connection in order to shorten the customer restoration time.  A purchase order was issued on June 6, 2007. ABB has ordered a capacitor bank, circuit breakers, disconnect switches and other long lead items.  Construction is expected to start in late Fall 2007 or early Winter 2008, and be completed before May 1, 2008.

 

12,470-Volt Distribution System

 

The engineering and construction work to rebuild and energize to 12 KV the 4 kV feeder areas A-8, A-96, and A-97 is nearly done. All customer stations have been rebuilt to 12 kV. This will allow conversion of this area to 12 kV service from the new Hollywood Way Distributing Station (Feeders HW-4 and HW-6). It goes along with BWP�s plan to transfer load to new state-of-the- art substations like Hollywood Way, and will eliminate aging substations like the Alameda Substation. The residential portion of Feeder A-8 was converted to HW-4 on June 6, and the commercial portion, including Vons grocery store at Pass Ave. and Oak St., will be converted on July 1, 2007. The first portion of Feeder A-96, south of Verdugo Ave. and west of the Warner Ranch to the City�s boundary, was energized to 12 kV on June 13. The remaining area, bound by Verdugo Ave., Clark Ave., Pass Ave. and Clybourn St., is scheduled for conversion on July 17.  Approximately half of the Feeder A-97 load bound by the area of Hollywood Way, Clark Ave. Pass Ave. and Verdugo Ave. will be energized to 12 kV in August, and will be served by HW-6. The remaining half of the load east of Hollywood Way between Verdugo and Oak Sts. will be transferred to Alameda-9 in the fall.  After completion of this work, Alameda Feeders A-96 and A-97 will be physically removed from the Alameda Distributing Station and the Feeder A-98 load will be transferred to the vacant position of Feeder A-8. This work is also required as a part of the Caltrans SR-134 project and will allow the positions of A-96, A-97 and A-98 feeders in the Alameda Station to be removed as well as the Transformer Bank A-3 serving them.

 

Progress continues on single pole replacements. Rebuilding deteriorated pole lines will start as soon as the reconductoring work is complete.

The Keystone and Golden State Distributing Stations were included in the under-frequency load shedding scheme to provide better capability to automatically shed load and balance load with generation. This addition will help to stabilize and restore the system much faster in the event we lose a big generation source such as the tie with LADWP or MPP.

 

Customer Transformer Stations

 

Since July 2006, Engineering has responded to 155 written requests for review and comments from the Community Development Department and other City Departments.

New business, and a strong residential real estate market, has created a demand for new customer stations.

In June, Engineering designed 7 replacements of deteriorated padmount transformers. Two vault-type customer stations have been removed and will be replaced by padmount switch/padmount transformer services.  Both designs will contribute to the expansion of the underground loop system.

 

Project Lightspeed

 

Engineering has processed 147 submittals from the AT&T Project Lightspeed.  The crews have energized 120 services completed by AT&T contractors.

 

 Undergrounding

 

Underground Utility District No. 1: The City Council approved the establishment of the first Underground Utility District within the City of Burbank for Olive Ave. between Victory and the I-5 overpass.  Construction started in early April and is progressing very well. Except for final paving, J Fletcher Creamer has completed the underground conduit work at Olive Ave. between Victory Blvd. and Lake St., and Lake St. between Olive Ave. and Orange Grove Ave., and along Orange Grove Ave. They also completed underground conduit work in the alley north of Olive Ave. and east of Victory Blvd. behind the 7-11 store. They installed maintenance vaults and conduit at Victory Blvd., both north and south of the Olive Ave. intersection, and Olive Ave. between the I-5 Bridge and Victory Blvd. In the mean time, the Okonite Company has delivered all of the 69,000-volt cable to the BWP campus. Undergrounding for Phase-1 including the cable installation, is estimated to be complete by October 31, 2007 and removal of the overhead poles and wires by November 30, 2007.

 

Caltrans: BWP Engineering completed two projects related to Caltrans. One project involves the Alameda, Hollywood Way and Pass Ave. bridge widening on the SR-134, and a new on-ramp at Hollywood Way. The second project involves the I-5 freeway, Empire Exchange, and San Fernando Realignment. Caltrans awarded the contract for the SR-134 Project and requested a Utility Agreement be approved.  The City Council approved the agreement on March 13, 2007, and extended the contract with Bock Company for the duct work. Bock Company started work at Riverside Dr., between Olive Ave. and Hollywood Way, and modified the communication pull box in front of the Alameda Distributing Station to allow space for adding an east bound right hand lane between Hollywood Way and the proposed on-ramp. Bock Company will continue to support BWP as needed to meet the schedule of the Caltrans Project. As of June 8, 2007 Bock Company has completed most of the work along Riverside Dr. between Olive Ave. and Hollywood Way. Caltrans has started widening the north side of the Alameda Avenue Bridge over SR-134.  Starting August 15, 2007 Bock Company will install electrical ducts in the bridge and work towards the intersection of Alameda Ave. and Hollywood Way. On the north side of the Alameda Bridge all cable installation and transfer of load to the new system is expected some time in November 2007.

 

Meters

 

BWP staff replaced 2,480 residential meters during Fiscal Year 2006/07. Of these, 856 were requested by customers, 118 were to saturate meter routes, 850 were replaced by electric field crews opportunistically, and 656 were replaced by Customer Service personnel opportunistically.

Staff installed 200 Time-Of-Use (TOU) capable meters during Fiscal Year 2006/07. To actually use TOU meters a software key and a TOU battery is needed.

 

Streetlighting System

 

In Fiscal Year 2006/07, 90 streetlight standards and 24 lights on power poles have been installed.  Out of these, 52 streetlight standards were installed as a part of the South San Fernando Blvd. Street Improvement Project, 9 streetlight standards were installed as a part of the Empire Ave. Street Improvement Project, and 8 streetlight standards were installed as a part of undergrounding the streetlight system on Olive Ave.  Two series circuits were converted to low voltage, and 9 rusted out streetlight standards were replaced during the fiscal year. Engineering worked with Public Works and the Traffic Signal Division on several new street/traffic improvement projects (several Burbank Blvd. intersections, Main/Victory, Third/Verdugo, Hollywood Way/Winona, and Hollywood Way/Thornton).

Water is Life Student Art Contest

 

Burbank Water and Power is proud to announce that one of its entries in Metropolitan Water District�s Water is Life student art contest was a winner!

 

BWP�s Water is Life student art contest was held from March 2007 to May 2007. We received over 60 entries from Burbank, John Burroughs, Providence, Monterey, and Bellermine-Jefferson High Schools as well as David Starr Jordan Middle School. After judging from Burbank Mayor Marsha Ramos, local professional artist Nan Rae, and BWP�s Lena Babayan, the top five posters were selected. These five posters continued on to compete in Metropolitan Water District�s competition against entries from 25 other water agencies. Of the five posters submitted by BWP, one, shown below, went on to be a winner and will be featured on various promotional items and will be part of a traveling art show. The winner, Sandra Kang, was from Burbank High School and was also BWP�s grand prize winner. Miss Kang will be honored by the Metropolitan Water District for her work at a special ceremony in December. 

 

 

Conservation Staff at Community Events

 

The City is hosting a number of events as part of a community outreach program to specific neighborhoods.  BWP Conservation Services staff members attend these events to educate residents on energy and water saving programs. 

 

The Golden State BBQ of May 19 and the Verdugo Street Fair of June 2 were successful events with 300 to 500 Burbank residents showing at each.  In addition to providing information about energy and water conservation in both English and Spanish, promotional items including low-flow showerheads were provided.  Between the two events, nearly 80 households signed up for upcoming conservation classes.
