      Copper Crossing Solar Ranch goes online
      Nearly a year after the Iberdrola Renewables announced their plans to build a photovoltaic solar power plant on 144 acres of former private agricultural land in San Tan Valley, the Copper Crossing solar power plant has gone online. Copper is now producing 20MW of solar energy, approximately 54 million kilowatt-hours annually, enough to power approximately 3,700 Salt River Project customers’ homes. SRP has designated most of the energy from this facility for schools, school districts and/or industrial customers. Approximately 10 percent is reserved for residential customers.

      DoE Awards $90M for 30MW Concentrating Solar Photovoltaic Plant
      The U.S. Department of Energy awarded the financial incentive to Goldman Sach's Cogentrix from a program designed to support the use of innovative technologies. The 30-megawatt already under construction will use high-concentration photovoltaic solar cells … It is expected to cost between $140M and $150M, and will be online by April 1 [2012?].

      CA Commission Could Pre-empt County/City Authority of PV Projects
      Although the Solar Trust case only deals with one project, it could lead to more requests from developers to have the commission oversee PV power plants. That could, in effect, strip counties and cities of the ability to have the final say on PV power projects (if a project is on federal land, then the federal government is in charge).

    8. Japan's Largest Solar Plant Regrets Small Storage

      Japan's Largest Solar Plant Regrets Small Storage
      At the nation's largest photovoltaic power plant in Sakai, Kansai Electric Power introduced an energy storage facility accommodating 48 nickel hydride batteries near KEPCO's substation … At Sakai, up to 10,000 kilowatts of electricity is generated during the current trial run ahead of the full operation starting in October. On cloudy and rainy days, however, the output drops to around 5,000 kilowatts and 2,000 kilowatts, respectively. To make up for the gap and achieve stable supply, KEPCO plans to release electricity accumulated in the energy storage facility on sunny days. Since the utility did not adopt highly-efficient lithium-ion batteries at the energy storage facility for financial reasons, there is a limit to the amount of electricity it can cover on bad weather days. Despite being the nation's largest photovoltaic power plant, its output is roughly one-hundredth of that of a nuclear reactor.

      U of Hawaii Selects Altairnano for 1MW Solar Storage Integration Test

      Altair Nanotechnologies announced it has signed a contract with the Hawai'i Natural Energy Institute (HNEI) of the University of Hawai'i at Manoa to supply a one-megawatt ALTI-ESS energy storage system for a test of solar energy integration. Altairnano will provide the ALTI-ESS battery-based power management system to be tested on Hawaiian Electric's electric system to smooth the voltage and load profile with the aid of dynamic voltage controls and fast charge/discharge abilities.

      Good Overview of "Post-stimulus Financing" of Renewables
      Money is flowing worldwide for many forms of renewable energy, as the industry presses forward with dramatic growth. CleanEdge reported US$188.1 billion in global revenue for biofuels, solar and wind energy in 2010, a 35.2% surge over 2009. Bloomberg New Energy Finance (BNEF) found that clean energy investment worldwide reached $243 billion in 2010, nearly double the sector investment just four years earlier. And venture capital investment for clean technology in the US rose 54% in the first quarter of 2011 compared with the same period one year earlier, in a trend led by solar energy companies, according to Ernst & Young … But will the growth continue as stimulus funding winds down?

    14. Analysis: Sunk costs of Hydro, Nuke, Coal, & Nat Gas Suppresses Renewables & Storage

      Analysis: Sunk costs of Hydro, Nuke, Coal, & Nat Gas Suppresses Renewables & Storage
      The increased cost comes from curtailment of renewable generation that occurs because thermal generators will choose to stay at a minimum level of operation even when uneconomic for them to do so at that specific time interval. That is to say the costs of turning off and turning back on are higher than the costs of operating below cost for a few hours. Because much of the electric grid is “inflexible”, this is an important area to consider for continued integration of renewables. Thus, this is one of the main reasons for consideration of storage technologies to reduce curtailment of wind and solar generation: renewables will be curtailed even before the total electrical demand becomes less than instantaneous renewable generation due to the inflexibility of the thermal power plants.

      Fraunhofer Off-grid PV Farming Solutions Without Storage
      The Fraunhofer energy management system monitors the amount of energy produced and then ensures that it is delivered to the devices that need it most. To illustrate, a submersible pump, which is 105 feet deep, can be powered to fill a reservoir when energy is available and the irrigation pump or desalination unit at other times. Only a relatively small battery is needed to ensure the CPV tracker and measuring system remains powered.
