Rewards, challenges and options for rate-based investments.
Utilities traditionally have met renewable portfolio standards with power purchases from IPPs. But new approaches are allowing utilities to build their rate bases with investments in solar generation.
Technologies are scaling up quickly to meet industry needs.
Like other California electric utilities, San Francisco-based Pacific Gas & Electric (PG&E) has been scrambling to meet the state’s renewable portfolio standard (RPS), which requires suppliers to obtain at least 20 percent of their power from renewable energy sources by 2010. Though the RPS includes a variety of technologies, renewables developers are choosing utility-scale solar power more than any other resource, says Hal La Flash, PG&E’s director of emerging clean technologies.

With the administration and Democratic lawmakers in Congress pushing to enact greenhouse-gas (GHG) regulation, nuclear power has taken center stage as both a clean technology solution and a political bargaining chip. Consequently, the industry’s hopes for new construction projects have brightened considerably. Whether this policy momentum can usher in a sustainable nuclear renaissance, however, remains questionable at best.
