Wind

Following the money invested in projects is a viable way to compare growth trends for power projects using the four major generation types: coal, natural gas, nuclear, and renewable.

Harvard Business School Professor Clayton Christensen coined the term "disruptive technology" in his best-selling 1997 book, The Innovator’s Dilemma. According to Christensen, a disruptive technology unseats a dominant technology by creating products that are so much cheaper or better in one or more ways that they quickly become the new mainstream standard, transforming an entire […]

Safeguarding coal-handling assets;
Giant wind turbine hard to bear

Utility resource planners are used to viewing new generation in terms of firm, dispatchable capacity. Dispatching a renewable resource such as wind requires a different perspective. Wind capacity can serve as a hedge against fossil fuel price risks and perhaps future emissions restrictions, but it requires a much more structured planning horizon. Integrating wind farms into their portfolios may be the most difficult challenge utilities face today.

The wind energy business is beginning to look as frenetic as the merchant gas-fired power business in the late 1990s—with some critical differences. If the 10 issues listed here are addressed soon, wind power may avoid a crash and burn similar to the one that beset the gas turbine business.

The length of term allowed for power sales contracts is a critical determinant of the ability of states to meet their increasingly ambitious renewable power targets. Many utilities advocate limiting terms to 10 or perhaps 15 years for renewable energy contracts, emphasizing the "flexibility" that shorter terms offer. In contrast, contract terms of 20 or […]

U.S. wind power is on a roll, with wind farms sprouting like weeds. But in the near future, utilities may end up paying higher prices for wind capacity because state regulators are, in effect, imposing an artificial floor on national demand for generation fueled by renewable resources. At last count, at least 20 states had […]
