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.

The nuclear renaissance requires safety as its central focus. Industry vigilance at all levels is key to accident prevention, but only favorable public opinion will allow the industry to realize its enormous potential.

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.

Historically, conservation has suffered from a fundamental challenge: it’s boring. But as efficiency becomes the first fuel, providers of efficiency services will begin to look more like businesses and less like government agencies—characterized by dynamic branding, with marketing strategies driven by customer science.

In 2006, the California legislature and governor positioned energy conservation and efficiency as the cornerstone of the state’s Global Warming Solutions Act. The Act mandates a 2020 statewide limit on greenhouse gas (GHG) emissions to 1990 levels. Compliance will be nothing short of Herculean: California will have to reduce per capita energy usage in a manner that accommodates continued brisk population growth and protects the state’s economy from economic dislocations and recessionary pressures.

Achieving the smart grid’s potential requires a revolution in electricity pricing. Smart metering and smart rates might yield surprising and beneficial changes in the U.S. utility industry. But capturing those benefits will require an intelligent and careful approach to implementing dynamic pricing.

The future of natural gas supplies in the United States looks promising due to rising projections of recoverable resources, including unconventional production. A strong supply outlook bodes well for using natural gas as a low-emission transportation fuel.

Many green power customers benefit from long-term fixed prices. The most effective programs recognize the value of this price hedge—and fairly exempt customers from fuel cost adders in utility rates.

Unconventional gas and LNG are changing the outlook for future gas prices.
