Pre-approvals demand a new approach to managing risks and costs.
Proving the need for new infrastructure construction for energy purchases has become more complicated for utilities. State commissions reserve the right to revisit rate-base investments after the fact, even when they’ve been pre-approved.
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.
