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.

One year ago, in the midst of the financial crisis, one industry—energy utilities—continued accessing the capital markets. Since then, interest rates and terms have improved dramatically, inviting utilities to refinance billions of dollars in debt that won’t mature for another year. Despite the current rosy picture, however, economic trends might cast a shadow over the industry’s capital-investment plans.

Renewable generation resources have become the rallying cry for policymakers and developers alike as the movement grows to generate electricity in a more climate-friendly manner. Pending federal legislation creating a carbon cap-and-trade market and a national renewable portfolio standard (RPS), together with existing state requirements, is spurring utilities that lack renewable generation to acquire some—no matter the federal legislative outcome—and causing utilities with sizeable renewable generation to expand their existing portfolios.

In light of coming GHG legislation, price transparency is the key to achieving cleaner generation through the dispatch of lower-carbon sources.

New federal policies have opened the gates to utility investments in renewable generating plants. Some states, however, still make it difficult for utilities to put such assets into the rate base. Executives at Duke, OG&E, PG&E and Xcel Energy discuss challenges and opportunities affecting their renewable investment strategies.

Utilities are leaving no stone unturned in their search for ways to save electricity. Federal incentives will support new technologies and projects, but can those incentives overcome structural barriers that stand in the way of major efficiency improvements? editors explore challenges and opportunities arising from the new efficiency mandate.

Photovoltaic technologies are beginning to appear more attractive than concentrated solar thermal plants. PV’s competitiveness is improving from technical and operational advancements, as well as significant commitments made by such utilities as Southern California Edison. In the long run, distributed central PV plants likely will gain a strong market position.

Perceval’s sagas are largely forgotten today, but at least one of them serves as a useful metaphor for an industry seeking the proverbial Holy Grail of clean-energy technology—specifically, the tale of Perceval and the Fisher King.

Fast forward to today’s partially deregulated electric power markets. Wholesale electric energy often is traded in various central markets, as well as among individuals in bilateral transactions. Wholesale electric energy prices largely are deregulated, and clearly, over the past decade, market participants have become adept at routinely charging much more than their variable production costs. This “rent extraction,” as economists commonly call it, can take various forms, and while the mechanism for achieving it can be complicated, the evidence is quite clear that today’s wholesale electricity prices typically are higher than the variable costs of most or even all suppliers.
