  • Which Side of the Meter Are You On?

    Utilities have achieved success by supplying electricity from central station plants (the supply side) to a grid that carries electricity to customers (the demand side). One way to improve the efficiency of this supply chain is by adopting smart grid technology. The weak link in that chain is convincing customers to use, and regulators to invest in, the smart grid.

  • 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.

  • MIT Researchers Invent Self-Renewing PV Technology

    Scientists at the Massachusetts Institute of Technology (MIT) have a created a set of self-assembling molecules that can turn sunlight into power, and which can repeatedly be broken down and reassembled by adding or removing solution. The scientific breakthrough—inspired by a natural process used by plants to renew light-capturing molecules that have been degraded by the sun—could mean that researchers are closer to creating a self-healing photovoltaic (PV) technology that can keep repairing itself to avoid loss in performance.

  • GE Launches 9.5-MW Engine for Distributed Generation

    A 9.5-MW gas engine unveiled by GE this October for decentralized, independent power producers in remote, hot, or high-altitude regions features a 48.7% electrical efficiency and promises to reduce lifecycle costs by lowering fuel consumption.

  • Investigating the Sayano-Shushenskaya Hydro Power Plant Disaster

    The destruction of the turbines and auxiliary equipment at Russia’s Sayano-Shushenskaya Hydro Power Plant in August 2009 claimed the lives of 75 workers and wrecked an indispensable source of electricity that will take years to fully restore. The disaster, as this report explains, was predictable and preventable.

  • UK Cancels Tidal Barrage Plans, Approves Key Nuclear Sites

    The UK government in late October shelved plans to build the Severn barrage—a project that would have involved building a 10-mile dam across the mouth of the Severn River—after a two-year-long feasibility study failed to convince ministers to use public funds to build it. The Department of Energy and Climate Change instead gave its long-awaited approval to eight sites for new nuclear reactors, saying that private companies could begin building the country’s new fleet of reactors, provided no public subsidy is involved.
