The Solar Electric Power Association (SEPA), released its third-annual Top Ten Utility Solar Rankings. Pacific Gas & Electric Co. (PG&E) topped the list of utilities with the most solar megawatts added to the grid for the second straight year with 85.2 MW, but new additions to the list and overall growth in solar integration by utilities defined 2009, according to the report. The top 10 utilities’ solar MW added to the grid grew from 169 MW in 2008 to 279 MW in 2009, a growth of 66 percent in a year when electricity demand as a whole declined as the result of the economic downturn. These 10 utilities represented 80 percent of the survey total. The results of SEPA’s research suggest that this growth was sparked in part by a drop in price for photovoltaic modules and systems worldwide. Joining the top 10 this year (see Figure 1) are Florida Power & Light Company at number 4 (29.5 MW, not ranked in 2008); Arizona’s Salt River Project at number 8 (5.8 MW, ranked 25th in 2008); and the Los Angeles Department of Water and Power at number 10 (4.889 MW, ranked 12th in 2008).

Abengoa Solar began commercial operation of Solnova 3, a new parabolic trough technology plant located at the Solúcar Complex in Seville, Spain. Abengoa Solar says the plant integrates some new technology enhancements to the ASTRØ parabolic trough collector, with construction and alignment processes intended to improve precision. This plant has the same features as its predecessor, Solnova 1, which began operating commercially at the beginning of May. Abengoa Solar says that with the additions, it has placed 143 MW of generating capacity into commercial operation, with another 350 MW under construction and several thousand under consideration.

Kiewit Corp. chose Alstom equipment to add 100 MW of steam-generated power to a new natural-gas-fired combined-cycle power plant being built in Saskatchewan. The equipment will be used in a new base-load power plant developed and owned by Northland Power of Toronto. The contract includes the supply of a steam tail (i.e., a 100-MW steam turbine, a generator and a heat recovery steam generator, or HRSG) and Alstom’s Alspa 6 turbine control system. The steam tail will bring the plant’s total power output to 285 MW. All power produced by the plant will be sold under a PPA to SaskPower. Construction is expected to begin in July 2010 with commercial operations in 2013. Kiewit also chose Alstom to provide air quality control systems to meet stringent Massachusetts clean air regulations for Dominion Resources’ Brayton Point Station in Somerset, Mass., which Dominion purchased in 2005. Under the terms of the $35 million contract, Alstom will supply a dry flue gas desulphurization system including NID reactors, fabric filters, mixer-hydrators, day silos, inlet and outlet plenums, support steel, and access platforms for unit 3 at the facility. Brayton Point is New England’s largest fossil-fueled generating facility with an output of 1,568 MW.

GeoGlobal Energy LLC (GGE), has become the largest investor in the first stand-alone, high-temperature flash technology geothermal power project to be developed in 20 years in California’s Imperial Valley, one of the largest geothermal resources in the world.

It will use the Stirling Energy Systems (SES) SunCatcher solar dish to provide 850 MW of power. S&C’s services will include power flow modeling of the SunCatcher system; stability, short circuit coordination, and dynamic simulation studies; and design of the collector system. S&C also has revised dynamic modeling of the SunCatcher, integrating control system improvements by SES, the manufacturer of the SunCatcher, into the electrical system model.

SunEdison, the solar energy development division of MEMC Electronic Materials, Inc. agreed with First Reserve Corp. to establish a joint venture that could provide for the acquisition of up to $1.5 billion in current and future SunEdison solar photovoltaic energy projects. SunEdison has more than 350 solar electric power plants constructed and under management. First Reserve is a private equity and energy infrastructure investor with $20 billion under management. SunEdison and First Reserve say this joint venture will be one of the largest world-wide energy infrastructure enterprises focused on the long-term ownership of solar photovoltaic generation assets.

Efficiency & Conservation

The Government of Saskatchewan, Canada and Hitachi Ltd. signed a joint declaration to work together and share information for developing energy and environmental technologies, including carbon capture and storage (CCS) for thermal power plants, renewable energy and smart-grid technologies. The agreement is Saskatchewan’s first such agreement with an energy company in the energy and environmental technologies field and aims to strengthen existing efforts to commercialize low-carbon energy technologies. Additionally, it’s expected to enhance energy security, while assisting in protection of the environment and natural resources. A primary focus of the agreement is to commercialize low-carbon energy technologies that involve CCS. Saskatchewan is home to the world’s largest monitored CCS demonstration project.

Ash Improvement Technology (AIT), a start up based in the New York City area, closed on Series A financing from a group of private investors aimed at taking on the 130 million tons per year of coal ash produced in the United States. Proposed coal ash regulations are under consideration and EPA estimates the incremental clean-up costs at $600 million to $1.5 billion a year, but industry insiders say it could cost as much as $12 billion. AIT’s approach transforms waste ash into a cement substitute, using sorbents applied on site at coal-fired power plants. The residue collected in the power plant’s existing collection systems can be sold immediately for beneficial use without further treatment. That results in less coal ash being landfilled, and also includes a reduction in CO2 emissions. According to AIT, each ton of treated ash used in lieu of cement saves nearly 0.85 tons of CO2 emissions. AIT’s infusion of funds will be applied toward making the process available commercially during the second half of 2010.
