  • Maintaining Grid Reliability with a High Renewables Portfolio

    The first problem with high renewable penetration is that wind and solar are not dispatchable.

  • California’s Streamlined DG Interconnection Process Bodes Well for Solar

    The California Public Utilities Commission (CPUC) last week approved a deal involving the state’s major utilities and renewable energy advocates that is  aimed at streamlining the process for connecting distributed generation (DG) resources to the grid. The CPUC’s action will make it easier for small amounts of distributed resources—such as rooftop solar photovoltaic (PV) systems—to connect to the grid. The agreement also revises upward the amount of DG that can be connected to a specific power line segment without the need for supplemental studies.

  • Ariz. Now Home to World’s Largest Solar PV Plant

    The title of world’s largest operating solar photovoltaic (PV) power plant goes to Arizona. On Monday, First Solar Inc. announced that the Agua Caliente solar project has achieved a peak generating capacity of 250 MW connected to the electrical grid. The project, under construction in Yuma County, will have a total capacity of 290 MW when completed.

  • DOE Offers $10M to Bring Down Rooftop PV "Soft Costs"

    The Department of Energy (DOE) on Wednesday announced its SunShot Prize, a new competition to make it faster, easier, and cheaper to install rooftop solar energy systems. A total of $10 million in cash awards are available to the first three teams that repeatedly demonstrate the non-hardware costs, or price to plug in, can be as low as $1 per watt for small-scale photovoltaic (PV) systems on American homes and businesses.

  • Congressional Briefs: Back from Recess

    Congress has returned from its summer break. As the House prepares to vote on its Upton-Stearns "No More Solyndras Act," lawmakers also expect to focus on a bill that could prohibit finalization of any Environmental Protection Agency (EPA) power plant rules that curb greenhouse gas emissions while carbon capture and storage technology is commercially unavailable. House Democrats, meanwhile, called for hearings to examine the impacts of climate change on the nation’s generators.

  • Chile’s Power Challenge: Reliable Energy Supplies

    Droughts, unreliable gas imports, and protests against proposed projects have hampered the Chilean power sector and its largest economic driver, the copper-mining industry. Recent policies designed to foster more reliable supplies are a move in the right direction, but remaining obstacles are formidable.

  • Trade Representatives Request Investigation on U.S. Renewables in Global Context

    The U.S. Trade Representative on Monday asked the U.S. International Trade Commission (ITC) to investigate how U.S.-provided renewable energy services affect development of renewable energy projects worldwide. The ITC’s report, expected by June 28, 2013, will focus on the development, generation, and distribution of renewable energy—specifically onshore and offshore wind and solar energy.

  • Solyndra Story Doesn’t Get Stearns Reelected

    Washington, 17 August 2012 — Poor Cliff Stearns. The soon-to-be-former Republican congressman from Florida found out Tuesday that voters in his district didn’t much care about the ruckus he’s been raising about the Obama administration and its funding of the failed Solyndra solar photovoltaic maker.

  • Major Developments for Solid Oxide Fuel Cells

    Solid oxide fuel cells (SOFCs), which oxidize a fuel to produce electricity, have received much attention of late for the technology’s myriad benefits, including high efficiency, long-term stability, fuel flexibility, and low carbon emissions—all at a relatively low cost.

  • Smart Grid Award: Customers Motivate San Diego Gas & Electric’s All-Inclusive Smart Grid Vision

    “If you build it, they will come” has proven a risky strategy for some smart grid projects. One of California’s largest investor-owned utilities faced the opposite challenge—customers whose behaviors necessitated a smarter grid. Customer involvement in and support for smart grid plans is a major reason SDG&E’s smart grid efforts continue to garner accolades, including the 2012 POWER Smart Grid Award.
