PURPOSE
Staff seeks City Council approval granting authorization for
the General Manager of BWP to enter into a Power Sales Agreement with the
Southern California Public Power Authority (�SCPPA�) for the output associated
with 5% (10 MW) of the Milford Wind Corridor Phase 1, LLC (�Milford Wind�)
facility located in Utah. This request will involve approval of both an
Ordinance and a Resolution, as it is contemplated under the Power Sales
Agreement, that SCPPA will be purchasing the facility during the term of the
Agreement with Burbank�s proportionate share of the cost being financed through
bonds issued by SCPPA.
BURBANK�S
RENEWABLE PORTFOLIO STANDARD (RPS)
The Burbank City
Council adopted a Resolution on June 5, 2007 that set a goal of 33% renewable
energy by 2020 for BWP. Acquiring the renewable energy associated with Milford
Wind would be an important step in meeting Burbank�s RPS and in reducing the
production of Greenhouse Gas (�GHG�).
JOINT DEVELOPMENT OF RENEWABLE
ENERGY THROUGH SCPPA
To continue
building its renewable energy portfolio, BWP through SCPPA and with nine other
SCPPA members, participated in joint Request for Proposals (�RFP�) for renewable
energy projects from qualified renewable providers in 2002, 2005 and 2006. The
proposals were evaluated based on the following criteria:
�
Price of the energy over the term of the agreement
�
Project development experience and expertise
�
Stability and creditworthiness of the counterparty
�
Expected output of the project based on historic wind patterns
�
Transmission availability from the point of delivery to Burbank
�
Project status and energy delivery start date
On April 25,
2006, Council authorized BWP to enter into a renewable energy project
development agreement with other SCPPA members. This provided BWP the means and
opportunity to participate in large projects and take advantage of opportunities
of both economy and scale. The joint efforts through SCPPA have so far resulted
in renewable energy for Burbank from the following:
-
The power sales
agreement for Ameresco initially approved on Feb. 10, 2004 and subsequently
amended for a price increase from $63 to $65.25/MWh on June 27, 2006 for
energy from a landfill gas burning facility located west of Valencia,
California. This facility is still waiting for a permit from the SCAQMD and
is currently expected to go into service in late 2008.
-
The power sales
agreement with PPM Energy Inc. approved on June 27, 2006 for wind energy from
Wyoming. Burbank began receiving energy under this contract in July 2006.
Since its initial
solicitation for renewable energy projects in 2002, SCPPA has facilitated 155 MW
of renewable energy for eight of its members. The power sales agreement with
SCPPA for the output associated with 5% (10 MW) of Milford Wind, which is the
subject of this memo, arises from the 2005 SCPPA RFP.
THE MILFORD WIND PROJECT
The facility will
be located in Beaver and Millard Counties in Central Utah.
Milford Wind Corridor Phase I, LLC "Milford Wind"
is a subsidiary of UPC Wind Management, which has five projects in North America
totaling about 300 MW (excluding Milford Wind). UPC Wind Europe has developed
about 650 MW in Italy and Sardinia. Milford Wind is a single purpose entity. It
is expected to become operational in December 2008 and consist of eighty (80)
Clipper 2.5 MW wind turbines for a total installed capacity of 200 MW. The
facility will interconnect to the Intermountain Power Project (�IPP�) Switching
Station located in Delta, Utah via a new 345 kV 60-mile line that will be built
as part of the project. From the IPP Switching Station, the energy will be
delivered to Burbank using rights that BWP has on the Southern Transmission
System � the same transmission facility we use to deliver energy from the
Intermountain Power Project.
The Milford Wind
Project is the best alternative available from the SCPPA proposals currently
under consideration for the following reasons:
-
The price of
the energy associated with the proposed power sales agreement is competitively
priced.
-
Burbank has
existing transmission in place to bring the power to Burbank from the point of
delivery at the Intermountain Power Project Substation in Utah.
The following
graph shows the anticipated hourly wind generation for the four seasons based on
historical wind data. This chart shows that a reasonable amount of energy can
be expected during the afternoon to early-evening period when energy has the
most value.
THE MILFORD WIND AGREEMENT
Under the
proposed contractual arrangements, SCPPA will pass through all the benefits and
obligations associated with a 200 MW wind project being developed in central
Utah by Milford Wind Corridor Phase 1, LLC, which is a wholly-owned subsidiary
of UPC Wind Management, LLC. Los Angeles would receive rights to 92.5% (185
MW), Burbank 5% (10 MW) and Pasadena 2.5% (5 MW).
The proposed
contractual arrangements have several unique features that haven�t previously
been used by either SCPPA or its member utilities. These features are expected
to be the template for future contracts and are as follows:
-
Ownership:
SCPPA and its members have an interest in the ultimate ownership of renewable
energy facilities. This will ensure a stable priced long-term supply rather
than relatively short-term power purchase contracts which must be periodically
re-negotiated with uncertainty of future availability or price. Accordingly,
if so desired by Los Angeles, Burbank and Pasadena, the contractual provisions
allow SCPPA to buy the project from the
developer.
-
Production
Tax Credits (PTC): Current tax laws allow generous federal tax credits
and favorable depreciation rules to private entities subject to federal income
tax. The transaction has been structured to allow SCPPA (and passed through
to Los Angeles, Burbank and Pasadena) to indirectly receive the benefits
associated with federal production tax credits valued at approximately $21
million.
-
Prepayment
for Power: A final feature that further improves the economics of the
transaction is through the prepayment for the power with proceeds derived from
tax-exempt revenue bonds that would be issued by SCPPA on behalf of the
participants. This feature is estimated to have a beneficial value of
approximately $23 million compared to a normal power purchase of the
facilities output.
Negotiations of
the agreements have been finalized and contain the following key terms:
-
Quantity:
Burbank will receive rights to 10 MW including all associated capacity, energy
and environmental attributes. BWP�s share corresponds to 5.00% of the
project�s output, or approximately 25,000 MWh/year at the expected annual
capacity factor of 29%.
-
Cost:
The overall total average cost of the energy at the point of delivery depends
on when and if, the buyout occurs. If buyout occurs early, the cost is
expected to be $74 - $76 per MWh. If buyout occurs around the 10-year point
into the contract as expected, the cost would be $71 - $73 per MWh.
-
Prepayment:
SCPPA will issue tax-exempt revenue bonds to prepay $269,502,397 on the
commercial operation date, which will have an annual debt service requirement.
In exchange for this payment, SCPPA is guaranteed to receive an amount of
energy associated with a 99% probability level of being produced, or 8,500,000
MWh of guaranteed generation over the 20-year term, in exchange for the
prepayment amount. Lehman Brothers has played an integral role in the
development of the financing and SCPPA�s Finance Committee recommends that
they be designated as the lead underwriter for the project.
-
Excess
Energy: In addition to the energy which is being prepaid, on average over
the term of the agreement, the facility is expected to produce an additional
1,668,560 MWh, depending on wind conditions at the site. SCPPA has the right
to purchase this excess energy at $56.94/MWh (plus the environmental attribute
charge discussed below), escalated at 1.75% per annum.
-
Renewable
Energy Credits: Burbank will receive all associated renewable energy
credits and other environmental attributes including credit for reducing GHG
emissions by offsetting electric generation from fossil fuels. Because the
environmental attributes of wind energy are considered �intangible,� and any
prepayments would be taxed in the year prepayment is received, the contract
has been structured so that SCPPA will pay $10.60/MWh, escalated at 1.75% per
year, for all environmental attributes produced by the project on a monthly
basis. This charge is included in the overall cost addressed above.
-
Taxes and
Insurance: SCPPA will reimburse Milford Wind for property taxes and
insurance associated with the project, not to exceed $4 million per year
escalated at 1.75% per year.
-
Term:
20 years starting December 31, 2008, unless the facility is purchased by SCPPA
which would result in perpetual rights to project facilities and the private
land for an initial term of 40 years with the right to renew for two
additional 10-year
terms.
-
Buyout:
SCPPA has the option to purchase the facility, including an undivided interest
in the transmission line to the point of delivery, from Milford Wind on the
10th anniversary of the commercial operation date at the fair market value of
the facility, subject to the power purchase agreement and not to exceed $150
million. Tax regulations require an arms length transaction at fair market
value, however, since the value will be subject to the power purchase
agreement, it will not be subject to inflated market prices for energy or
environmental attributes.
-
PTC Put:
The expected commercial operation date of the facility is currently expected
to be prior to the expiration of current production tax credits (�PTC�) which
expire at the end of 2008. The contract contains provisions that in the event
the commercial operation date slips beyond the expiration date of currently
authorized PTCs at the end of 2008, an extension of the PTC legislation would
be required to complete the transaction as contemplated. If either party
believes that the PTCs are likely to be renewed, then there will be a waiting
period of up to one year in which SCPPA would not make the prepayment on the
commercial operation date and SCPPA would pay $52.50/MWh (plus taxes,
insurance, O&M and the renewable energy attribute charge) until the PTC issue
is reinstated, but not longer than one year. If the PTCs are not extended by
the end of the one year waiting period, then SCPPA would be required to either
(i) pay an additional monthly payment to Milford Wind to make them whole for
the value of the PTCs or (ii) purchase the facility for $2,050 per kW of
installed capacity
RISK MITIGATION
The benefits of
the proposed structure require that a substantial prepayment be made to a single
purpose entity with no assets other than the facility. Since SCPPA is interested
in ultimate ownership of the facility, the agreement was structured to use the
facility itself as security for the prepayment. The prepayment and other risks
were mitigated as follows:
-
Prepay:
SCPPA will receive a first deed of trust securing all obligations of Milford
Wind under the agreement. The construction financing will be paid off at
closing, ensuring SCPPA�s first position. If Milford Wind defaults on the PPA
or seeks bankruptcy protection, then SCPPA could foreclose on the
facility.
-
Bankruptcy:
The PPA with Milford Wind requires that Milford Wind Corridor Phase I, LLC,
remain a single purpose entity during the life of the project with wind
generation being its only business purpose. The PPA also includes various
covenants designed to minimize the need for bankruptcy
protection.
-
Leases:
The facility is to be constructed on property leased from one large
landowner, the U.S. Bureau of Land Management, the State of Utah and several
small individual owners. The private leases comprise about two-thirds of the
property and have an initial term of 40 with two ten-year extensions. SCPPA
has negotiated a lease form that will ensure the assignability of the private
leases at the time of purchase and step-in and cure rights should Milford Wind
fail to meet its obligations pursuant to the leases. Also, Milford Wind
Corridor Phase I LLC, will be the direct lessee for all generator and
transmission property, and will not hold subleases, which may be subject to
the performance of other unrelated lessees.
-
Wind:
The wind resource is obviously weather dependent, but it is relatively
predictable on an annual basis. At least 90-days prior to the commercial
operation date, SCPPA will receive an estimate of guaranteed generation,
prepared by a third-party wind expert, based on the contract capacity of the
facility in order to determine the prepay amount.
-
Quality:
The PPA has a requirement that Milford Wind adhere to prudent utility
practices and an internal quality assurance program. SCPPA is protected by
having the option not to purchase the facility if the quality of construction
or maintenance is not satisfactory.
HOW RENEWABLE
ENERGY FITS INTO BWP�S RESOURCE PORTFOLIO
Because BWP is a
fully resourced utility, it is challenging to add renewable energy to our
portfolio and control costs. A way that it could be done is to back-down local
gas-fired generation as low as practical and substitute renewable energy. This
can be most readily and economically achieved using wind power. The idea is to
bring wind power to BWP while simultaneously reducing natural gas generation by
a like amount.
Because of its
high efficiency, the Magnolia Power Project (�Magnolia�) is expected to be
on-line most of the time. With current natural gas prices running around $8/Dth,
wind energy is competitive with the cost of generation from Magnolia. (Ignoring
variable O&M costs - $8/Dth natural gas run through a 7,500Btu/KWh heat rate
plant produces energy that costs $60/MWh.) Therefore, by backing down Magnolia
to minimum load levels and substituting intermittent wind energy, it would be
possible to increase the portion of renewable energy in our portfolio without
increasing costs. There is however a limit on how much our local generating
facilities can be �backed down� to accommodate renewable energy. The exact
point is difficult to ascertain because it is a function of when the wind blows
and generates energy, the time of year and Burbank�s energy requirements.
Analysis suggests that once wind energy reaches 6% to 8 % of our portfolio, the
aforementioned benefits of fuel displacement will begin to diminish and power
supply costs will begin increasing significantly.
BWP'S RENEWABLE ENERGY PROCUREMENT
STRATEGY
BWP has ongoing
efforts underway to ensure that it meets its RPS targets as described below:
-
Negotiations
are underway for wind power from a resource in the Pacific Northwest which is
expected to start producing energy in June 2009. Twenty (20) MW of this
resource would provide 4% of BWP�s energy requirements.
-
BWP has entered
into a development agreement through SCPPA with other members to study the
feasibility of jointly developing a 200 MW geothermal energy facility in
conjunction with Los Angeles Department of Water & Power (LADWP) and Imperial
Irrigation District (IID) in the Imperial Valley in California. BWP would get
this energy home via the proposed Greenpath Transmission Project being
developed by Los Angeles and scheduled for completion in June 2011. BWP has
an interest in ultimately acquiring twenty-five (25) MW of geothermal based
resources from this area and has been allocated an initial allocation of nine
(9) MW expected to go into service in 2011 when the Greenpath transmission
line is completed. Staff has expressed interest in an additional sixteen (16)
MW in a second phase project which is anticipated to go into service in
January 2013.
-
BWP is also
involved with five other SCPPA members in a development study looking at the
feasibility of green-waste to energy plants in the LA basin. The work on this
effort is just beginning and it is unknown at this time whether a project will
ultimately come out of the work, so it is not being included at this time.
The following
table shows the percentages of renewable energy that is existing, approved and
how planned renewable energy additions would contribute to BWP�s resource
portfolio and when they are expected to become available.
FISCAL IMPACT
The fiscal impact
of renewable energy on BWP is a function of several factors as follows:
-
BWP has
approximately $700,000 available annually in Public Benefit Funds to subsidize
the cost of renewable energy. However, how to make the best use of these
funds is a policy matter. One use would be to use the funds to subsidize the
out-of-market cost of renewable energy purchased from sources outside of
Burbank. Another would be to use the Public Benefit Funds allocated for
renewable energy to promote customer programs like the Solar Rebate program
for customers who install photovoltaic systems or large scale solar
demonstration projects like the proposed photovoltaic system that will be
incorporated onto the roof of BWP�s new parking lot. A particular difficulty
with using Public Benefit Funds to subsidize the out-of-market from third
parties is determining the appropriate level of such subsidies. The challenge
is placing a comparative value on energy from intermittent sources like wind
and from a power plant like Magnolia which can be scheduled. Staff believes
that the better use of Public Benefit Funds is for customer-related programs
and initiatives and therefore recommends that these Funds first be used for
such purposes, rather than subsidizing the cost of renewable energy from
parties located outside of Burbank.
-
Another factor
relates to how much of the renewable energy can ultimately be usefully used to
meet the native load requirements of Burbank. Referring back to the wind
profile presented earlier in this staff report, it is apparent that a
significant amount of the expected annual output of that project occurs during
the first eight hours of the day when BWP�s energy needs are the lowest. A
similar situation prevails with the Wyoming wind. As well, the output of the
Ameresco project is expected to be constant throughout the day, including the
early morning hours when customer loads in Burbank are at a minimum and the
Magnolia project is likely to be already operating at its minimum load. As a
result, it may not be possible to lower Magnolia�s output further in order to
absorb the wind energy. Since BWP cannot control when the renewable energy
from Wyoming wind, Ameresco and Milford Wind is going to be produced and the
fact that BWP has to take the energy when produced, it would likely be
necessary to sell off the �surplus� energy during those times of the day when
it is not possible or practical to off-load Magnolia or other generation. As
indicated above, this would normally be expected to occur during the early
morning hours. However, this is also the period of the day when other
utilities have also backed down their generation with the result being that
energy prices are typically the lowest during this time. As more renewable
energy is added, it is expected that an increasing amount of it will have to
be sold off at increasingly less attractive prices.
The following
table has been prepared to show the expected affect on power supply costs for
the projects mentioned earlier in this memo that BWP has under consideration, if
Public Benefit Funds are used to subsidize the out-of-market cost of renewable
energy from third parties located outside of Burbank. The table shows that it
would take approximate $289,080 to bring the cost of the renewable energy from
Milford Wind down to what it would cost to generate an equivalent amount using
Magnolia. (As discussed earlier, a reasonable proxy price for such Magnolia
generation would be $65/MWh comprised of $8/Dth natural gas run through a
7,500Btu/KWh heat rate plant which produces energy that costs $60/MWh plus $5/MWh
for O&M expenses.) Since BWP has $700,000 available from Public Benefit funds
to subsidize this contract, lowering its effective cost, there would be no
direct impact (increase) on expected power supply costs, as only $289,080 is
needed to mitigate the above market cost of the resource.
However, because
a significant portion of the energy from this wind resource is produced at
night, it is likely that it could not all be used to meet native load
requirements and would have to be sold-off. Based on the assumption that 20% of
the energy would have to be sold off at 65% of the contract price, the net
impact to BWP would be an increase in power supply costs of about $281,853
annually, corresponding to a potential impact on rates of about 0.2%.
Similarly, the table shows the impacts of adding all the other renewable energy
projects that BWP has under consideration which would potentially result in
cumulative rate increases of around 7.5%.
As discussed earlier,
staff believes that BWP should not use its Public Benefit Funds to subsidize
renewable energy from third parties located outside of Burbank. Instead, the
funds could be used for customer and demonstration programs. In view of this,
the previous table has been re-constructed below, showing the potential
cumulative impact on rates if Public Benefit Funds are not used to subsidize the
out-of-market cost of renewable energy. It shows that the Utah wind resource is
expected to increase annual power supply costs by $570,933 (rather than $281,853
when Public Benefit Funds are used) with an associated potential impact on rates
of about 0.4% and that BWP�s renewable energy procurement program would result
in cumulative rate increases of around 8%, if all the projects under
consideration by BWP are acquired, when Public Benefit Funds are not used to
subsidize the cost of renewable energy from third parties located outside of
Burbank.
Efforts underway related to GHG reduction and
regulation will likely necessitate that in the future, we scale back operations
of our coal facilities in order to meet GHG emissions standards. If that turns
out to be the case, under certain scenarios, BWP may be able to use all the
renewable energy it has contracted for retail load and not have to resell any
during off-peak periods. The extent to which GHG regulation may affect the use
of renewable energy is not known at this time as the standards are currently
underdevelopment and not expected to be finalized for several years.
RECOMMENDATION
Staff recommends City Council approval granting
authorization for the General Manager of BWP to enter into a Power Sales
Agreement with SCPPA for 5% (10 MW) of the Milford Wind Corridor Phase 1, LLC
(�Milford Wind�) facility located in Utah.
If the Council concurs, the appropriate action
would be to recommend that staff take the following two motions to Council for
approval:
1.
Introduction of proposed ordinance entitled: (motion and voice vote
only)
AN ORDINANCE OF THE COUNCIL OF THE CITY OF
BURBANK APPROVING ENTERING INTO THE MILFORD WIND CORRIDOR PHASE I PROJECT POWER
SALES AGREEMENT
2. Adoption of the proposed resolution
entitled:
A RESOLUTION OF THE COUNCIL OF THE CITY OF
BURBANK AUTHORIZING OFFICIALS TO EXECUTE AND DELIVER THE MILFORD WIND CORRIDOR
