First Megawatt-Scale Isothermal CAES Completion

SustainX in September completed construction of what it says is the world’s first megawatt-scale isothermal compressed air energy storage (ICAES) system. The system at the company’s headquarters in

CPUC Issues Nation’s First Energy Storage Mandate

The California Public Utilities Commission (CPUC) today unanimously established an energy storage target of 1,325 MW that California’s largest investor-owned utilities, Pacific Gas and Electric Company, Southern California Edison, and San Diego Gas & Electric, must meet by 2020. The decision will help California optimize the grid with measure such as peak reduction, contribute to […]

Your Guide to the White House Climate Action Plan

President Obama’s highly anticipated Climate Action Plan (CAP) released today outlines a wide variety of executive actions founded on three pillars: slashing U.S. carbon pollution through stringent rules for new and existing power plants while doubling renewables deployment and promoting fuel switching from coal to natural gas; preparing the U.S. for impacts of climate change; and leading international efforts to combat global climate change.

CORRECTED: Challenges to Order 1000 Filed in Federal Court as President Acts on Grid Modernization

Several power companies, state commissions, and trade groups have filed briefs with the U.S. Court of Appeals for the D.C. Circuit challenging parts of the Federal Energy Regulatory Commission’s (FERC’s) Order 1000, a rule they argue will lead to high costs for consumers and diminish the authority of state and regional regulators. Meanwhile last week, the White House issued a memo directing federal agencies to improve siting and permitting process to help modernize the nation’s grid.

Germany’s Energy Transition Experiment

Germany has chosen to transform its energy system within a few decades—an ambition that has evoked equal admiration and confusion. Has Europe’s largest economy embarked on a rational path to an energy future that will make it the bellwether for global acceptance of renewables, or will the complex array of current challenges encumber its grand transformation?

Distributed Generation: California’s Future

Once you synthesize all the elements of the Golden State’s clean energy strategy and extrapolate current trends, it’s easy to see that an impending break with the traditional power generation paradigm is coming, intended or not.

Emerging Technologies Enable “No Regrets” Energy Strategy

Achieving a balance between affordable and sustainable electricity while improving reliability is a challenge unlike any the electricity sector has faced since its inception. Technology innovations in key areas such as energy efficiency, smart grid, renewable energy resources, hardened transmission systems, and long-term operation of the existing nuclear and fossil fleets are essential to shaping the future of electricity supplies.

Improving Grid Resiliency After Superstorm Sandy

For the power generation and delivery industry, the lesson of Hurricane Sandy was how fragile much of the grid is. Distributed generation, smart grid technology, and combined heat and power offer cost-effective ways to improve grid resiliency.

Feds and States Join Forces to Push CHP

Though subsidies and incentives for wind and other renewables have grabbed the headlines, federal and state initiatives are quietly building some momentum behind combined heat and power.
