  • Power system reserve - No need to build wind back-up
    written by Lyn Harrison and David Milborrow
    Addition of wind generation to a large power system does not require construction of back-up generating capacity.

  • Storing up trouble in Japan
    Wind power in Japan is taking a battering, but this time it has nothing to do with typhoons and tornadoes and everything to do with the government's willingness to swallow utility tales about the prohibitive cost of adapting the country's power system for greater uptake of wind energy without massive...
  • Transmission - time to wield a big stick
    The rapid growth of wind power has turned the business of transmission and distribution on its head. All of a sudden, where transmission is needed most, in remote windy areas, there is none. And market incentives work against new transmission for wind. In America it is the same problem. Should transmission lines be build in the expectation that generators will turn up to use them, or should generation be built in the expectation that new wires will follow? Policy needs a
    rethink. Global eyes are on Britain and the solution it adopts.

  • Puncturing the storage myth
    Wind power's detractors and supporters alike all too often refer to electricity storage as if it were the solution to an otherwise insurmountable problem, one that prevents wind energy from being a big league generator. But the idea that storage is needed for wind is a myth. This article tells you why.

  • Transmission there but access blocked
    While construction of major new power lines cannot be put off for ever, better management of existing transmission capacity and some modest line improvements would free the way for thousands of megawatts of wind development across the United States.

  • The Real Cost of Integrating Wind
    What happens to your electricity supply when the wind stops blowing? Nothing at all. Windpower Monthly argues that for a good few years yet there is no need for dedicated back-up capacity to cover for when the wind stops blowing, or blows too hard, as any modern system has the small level of reserve required. That fact is masked, however, by poorly structured market frameworks which need amending.

  • Forecasting for Scheduled Delivery
    Windpower Monthly's comprehensive look at wind forecasting shed some interesting, and unexpected, light on this neglected topic. With more push towards accurate forecasting, we found that wind power is busy disproving die-hard utility theory that it can never provide significant volumes of power economically because it is a fluctuating resource.
  • Trading rules trap wind in the balance
    Despite growing evidence that the introduction of wind into an integrated electricity
    network does not result in any substantial rise in operating costs, David Milborrow reports on the failure of Britain's policy makers to introduce fair electricity trading arrangements which reflect that. Instead, he argues, a system based on balancing charges has been developed resulting in market distortions which unfairly penalise wind power and instead benefit fossil fuels.

  • REserviceS (Economic grid support from variable renewables) is the first study to investigate wind and solar based grid support services at EU level. It will provide technical and economic guidelines and recommendations for the design of a European market for ancillary services, as well as for future network codes within the Third Liberalisation Package.
