Two separate California Energy Commission siting committees have
released Presiding Member’s Proposed Decisions (PMPD) on amendments to
solar projects in Riverside County, the commission said in a Dec. 16
statement.
The committee for the proposed Blythe Solar Power Project
recommended approval of the amendment to convert to a 485-MW solar
photovoltaic facility, while the committee for the proposed Palen Solar
Electric Generating System recommends denying the amendment to convert
to a 500-MW solar thermal power tower project.
In the PMPD for the Blythe Solar Power Project released Dec. 13, the
committee finds that the project, as mitigated, may have environmental
impacts that are cumulatively significant when considered along with the
impacts of other projects in the region. The cumulative impacts that
cannot be mitigated to less than significant levels are to biological
resources, cultural resources, land use, and visual resources. The
committee finds that the project benefits—including its contribution to
meeting California’s Renewables Portfolio Standard, reducing greenhouse
gas emissions, creating an estimated 499 peak construction jobs, and
boosting the economy — justify an override of those impacts.
Commissioner Karen Douglas presided while Commissioner David
Hochschild served as associate member for the Blythe project committee.
The committee determined that the Blythe amendment complies with all
applicable laws, ordinances, regulations, and standards.
In regards to the Palen project, the committee found that the requested amendment,
like the currently approved solar trough project, will have significant
unmitigable impacts to cultural and visual resources. Unlike the
currently approved project, the committee found that the amended project
will also result in significant and unmitigable impacts to biological
resources due to the risk of solar flux on avian species. The committee
recommended denying the project amendment at this time. The committee assigned to the Palen project has scheduled a committee conference on Jan. 7, 2014 in Sacramento, Calif.
The two PMPDs are based solely on the record of facts established
during the facilities’ amendment proceedings. They are not final
decisions on these amendments. The committees have released both
recommended decisions for 30 days of public comment and will consider
input before the proposed decisions go to the full commission in early
2014. Commissioner Karen Douglas presided while Commissioner David Hochschild served as associate member for the Palen amendment.
Blythe Project Background
In September 2010, the commission approved the 1,000-MW Blythe Solar
Power Project, which was to use parabolic trough technology. The site is
located about eight miles west of Blythe in eastern Riverside County.
It was originally to be built on 7,043 acres of federal public land
managed by the U.S. Bureau of Land Management (BLM).
The project owner, Palo Verde Solar I LLC, a subsidiary of Solar
Millennium, filed an amendment with the commission in June 2012 to
change the technology to solar photovoltaic. The commission has no
jurisdiction over wind or PV projects but commission review was allowed
by the Legislature under Senate Bill 226 for a limited category of
projects approved on BLM land in 2010.
In April 2013, the new project owner, NextEra Blythe Solar Energy Center LLC, a subsidiary of NextEra Energy Resources LLC, filed a revised amendment to reduce the project’s physical size and generation capacity.
The amended 485-MW project would be developed on 4,070 acres of BLM
land in four phases, with the first three consisting of 125 MW and the
fourth of 110 MW. The project will also require a revised right-of-way
grant from the BLM. Construction on the project is expected to last 48 months. The
estimated capital construction cost is $1.13bn, according to the project
owner.
Palen Project Background
In December 2010, the commission approved the 500-MW Palen Solar
Power Project, which would use parabolic trough technology. In December
2012, the new project owner, Palen Solar Holdings LLC filed an amendment
with the commission requesting to change the technology to solar power
tower.
The applicant for the amended project now known as the Palen Solar
Electric Generating System is Palen Solar Holdings LLC, a joint venture
of BrightSource Energy and Abengoa. The amendment proposal consists of two 250-MW solar towers and
170,000 heliostats. Heliostats are elevated mirrors used to focus the
sun's rays on a solar receiver that produces steam to generate
electricity. The solar receiver would be located atop a 750-foot-tall
power tower near the center of each solar field.
The Palen project would be located about 10 miles east of Desert
Center, halfway between Indio and Blythe, in eastern Riverside County.
It is located on 3,794 acres of public land managed by the BLM, which is
separately reviewing the project.
