  • Smart Grid 2011: More than Meters

    The concept of a smart grid may have been born in the U.S.A., but it’s hitting an adolescent growth spurt just about everywhere else first. Meanwhile, in the U.S., both the regulators and companies that see great potential in a smarter grid are realizing that making substantial smart grid progress will first require making both people and policies smarter. There’s one exception, one piece of the smart grid, that could face fewer obstacles to adoption, and that’s because it offers more obvious and visible benefits to its users: electric vehicles (EVs).

  • Coal Plants Challenged as Gas Plants Surge

    European carbon trading is gradually pushing down coal-fired capacity factors, and operating costs are rising. The U.S. may not have a carbon market, but increasing regulatory requirements are having the same effect on coal-fired generation capacity factors and operating costs. In the meantime, gas-fired assets are enjoying increased usage and lower unit costs.

  • A Winning Combination: Government and Utilities Partner on Renewable Energy Projects

    Recent mandates require government facilities to develop energy policies that enable energy conservation, increase the use of renewable energy, and improve energy security. Utilities with government facilities in their service territory may have opportunities to develop solar and other renewable energy projects that help them meet state renewable portfolio standards while increasing a government facility’s usage of renewable energy. The key to such a win-win proposition is careful structuring of the project agreement to leverage each party’s assets.
