Everyone loves efficiencies. Combining generation technologies can create a plant that’s more than the sum of its parts, but engineering challenges mean these projects are not for the faint of heart. When you think of “hybrids” these days, your first thought is probably of automobiles. But hybrids—hybrid power plants, that is—are starting to emerge in […]

Stacking perovskites, a crystalline material, onto a conventional silicon solar cell may dramatically improve the overall efficiency of the cell, scientists from Stanford University concluded in a new study. “Right now, silicon solar cells dominate the world market, but the power conversion efficiency of silicon photovoltaics has been stuck at 25% for 15 years,” explained […]

Though offshore wind is becoming increasingly important in Europe, with many hundreds-of-megawatts projects in service, the sector has stagnated in the U.S., with no operational facilities—and some

While developers in the U.S. celebrated financial closing for the 15-MW Block Island Wind Farm off Rhode Island—the would-be first offshore wind farm in the U.S.—Germany said this month that it expects to commission about 2 GW of new capacity in 2015, adding to its total of 1,048 MW at the end of 2014. Though […]

Rooftop solar company SolarCity on Mar. 2 filed suit in federal court in Arizona seeking to overturn a new rate structure approved by the Salt River Project (SRP) that levies additional charges on customers with rooftop solar panels. On Feb. 26, the SRP board voted to approve a change in how it bills customers who […]

After decades of potential but limited deployment, fuel cells are beginning to carve out a role in grid-scale generation (see “59-MW Fuel Cell Park Opening Heralds Robust Global Technology Future” in the

Sometimes, circumstances have a way of developing in such an unexpectedly serendipitous way that they practically force one to take notice. So it is with Cuba and its power sector. Coincidence It all started

TIC to Build First U.S. J-series GT Plant. The Industrial Co. (TIC), a wholly owned subsidiary of Kiewit Corp. ,was recently awarded an engineering, procurement, and construction contract to build a gas

Contact Energy fully commissioned New Zealand’s largest geothermal power plant last year, nudging installed geothermal capacity to a shade over 1 GW. Nearly 80% of the country’s electricity is sourced from

Google and rooftop solar company SolarCity announced on Feb. 26 that Google is contributing $300 million to an investment fund that is expected to finance $750 million in rooftop solar installations, the two companies said in a statement. The investment is structured as a tax equity deal that will allow Google to reduce its tax […]
