The potential for a federal renewable energy standard (RES) and carbon regulation, considered with the effect of state-imposed renewable energy standards, is fueling a strong, but challenging, market for renewable energy. Utilities are competing to sign up the best new projects, the types of renewable technologies available are increasing, and there are various government stimulus programs for energy; yet, the financial markets still are hesitant. Against this backdrop, how should contracts for power from new renewable resources be shaped so that those deals will look as good five, 10 and 15 years after execution as on the day the ink dries?

23 million square miles of tropical oceans daily absorb solar radiation equal in heat content to about 250 billion barrels of oil. Ocean thermal energy conversion technologies convert this solar radiation into electrical power by exploiting the thermal gradient temperature differences between the surface and the depths. This enormous resource merits a closer look as policy makers consider alternative technologies for serving future energy demands.

With public opposition rising against almost any kind of utility project or investment, collaboration among stakeholders with widely divergent points of view never has been more critical. Three recent utility cases demonstrate how a formal stakeholder collaboration process can build support for otherwise contentious decisions.

The utility industry tends to think about smart-grid development as a technical challenge. However, smart-grid technology will fall short of its promise if utilities don’t obtain buy-in from customers. Successful utilities will actively engage customers at every stage of implementation, customizing their approach to the sensitivities and opportunities in each customer segment.

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.

As utilities announce new smart-grid programs, they need a strategic method for quantifying benefits. Analytical models generate baseline benefit estimates and reveal big-picture trends. Decision makers need the best resources available to mitigate risks in choosing a smart-grid strategy.

Who will oversee the industry’s cyber standards? Effective security calls for a single organization to set standards that will protect the smart grid. The industry is struggling to reach consensus over authority, scope and funding for its new security apparatus.

While much has been written about the intelligent grid of late, little attention has been focused on the role of energy storage in achieving its expected benefits. Energy storage is an essential component of the intelligent grid. Energy storage provides greater grid integration of variable renewable energy resource output (e.g., wind, solar); improved system reliability via the provision of grid regulation services; and peak demand reductions and, in turn, deferred capital spending on new and upgraded transmission and distribution assets.

A once-in-a-lifetime confluence of forces is re-shaping the business models of America’s electric utilities. Rising costs, combined with technological advancements and shifts in regulatory policy, are putting unprecedented pressure on companies that depend on market conditions. Those that adapt to the new realities will be better positioned for success in the future.
