U.S. power-plant construction tends to follow fads. Identifying these trends is easier than determining the primary drivers and issues that contributed to them. Understanding how these drivers affect power-planning decisions can help utilities predict generation-construction trends in the future and avoid getting caught in a group-think trap.

Utilities can meet state renewable portfolio standards—and reduce greenhouse gases—by burning biomass fuel. Whether utilities are prepared to jump into the biomass game, however, depends on how effectively they can manage fuel risks.

The heavy investment required for new generation technologies clearly is a global phenomenon, but global-resource competition to build power plants is making power-plant development more expensive—and may even limit the number that any one utility in any one country can develop.

Utilities are eager to invest in new power capacity—in part to build rate base and in part because they recognize the danger of relying too much on a single fuel source. Environmental issues, however, are adding greater complexity to company strategies for achieving fuel diversity.

Renewable Energy:

Mandatory portfolio standards have different implications for different technologies.

The federal government and several state governments are considering programs to increase the share of electricity produced by renewable generation resources to 20 percent or more. If these programs are implemented and pursued successfully, they will trigger a dramatic change in the role of renewable generation and the requirements placed upon it by the market.

Editor's Note

Several of the sources for this article and accompanying sidebars are referenced numerous times.

SOME PEOPLE WANT TO KNOW WHAT "GREEN POWER" means (em and, by extension, "environmentally friendly." Does that mean low emissions, including nuclear energy? Is renewable energy automatically green? Should the simple fact of compliance with all standards imposed by the Environmental Protection Agency afford the right to advertise power generation as green?

Consumers, agencies and state and federal officials want truth in advertising. Proponents of alternative generation claim consumers are willing to pay more for cleaner, greener energy.

Minnesota has lots of drafts, but no final plan.

So you think your state has been busy? In Minnesota, the 1997 legislative session saw more than a dozen new bills introduced on electric, gas and energy issues.

At the start of the session many expected that electric deregulation would play a major part in the legislative program. However, Gov. Carlson reports now that legislators will defer work on the issue until the 1998 session. Several electric industry deregulation bills were introduced at the end of the session, but when last we checked no hearings had been held.
