Renewables

Although today microgrids serve a tiny fraction of the market, that share will grow as costs fall. Utilities can benefit if they plan ahead.

The U.S. Treasury cash grants for new renewable power projects expired at the end of 2011. These incentives, which were implemented under Section 1603 of the American Recovery and Reinvestment Act of 2009, helped to support continued capacity additions throughout the recession. The impending expiration of these grants caused a wave of merger and acquisition (M&A) activity during 2011 as developers and financiers rushed to get deals done and to begin construction in order to meet the Section 1603, 5-percent safe harbor threshold by the Dec. 31, 2011 deadline.

Notwithstanding some past difficulties, trash-fired power plants represent an increasingly attractive opportunity for future clean generation investment. Waste fuel offers a green source of baseload power that’s competitive with fossil fuels. The technology is proven and mature, and it enjoys public policy support. Additionally, waste fuel will help utilities meet diversity goals and environmental mandates.

Where wind integration has been most successful, state authorities developed and adopted basic transmission planning and cost allocation principles before FERC issued Order 1000. Experiences in Texas, California, and Hawaii demonstrate what it takes to overcome permitting and cost allocation barriers—namely, a coherent policy framework and close coordination among stakeholders.

New technologies—and new expectations—require taking a fresh look at the institutions and practices that have provided reliable electricity for the past century. Collective action is needed to define the key attributes of a future grid and then to take the more difficult next step—adapting our processes and institutions to align with that future vision. A thoughtful approach will allow America to capture the potential value that’s offered by sweeping changes in technologies and policies.

Policies aimed at promoting one good thing can diminish a better thing, for a net loss to the overall public welfare. Raising prices to promote renewables, for example, makes electricity less affordable and hurts the economy. But artificially low prices can themselves create social ills — by preserving an unsustainable status quo.

With large solar arrays and wind farms being proposed to connect to transmission and sub-transmission systems, are utility companies sufficiently prepared to handle the challenge of integrating these large intermittent resources? The industry now must decide whether transmission reliability factors — most notably dynamic voltage support and system frequency management — need to be resolved by renewable generators, or whether they should become a cost of doing business for transmission providers and reliability coordinators.

Some of the key policy mechanisms and market factors that triggered the boom in renewable energy development have weakened in the face of one of the most severe economic downturns in modern history. In some ways, though, the renewables sector is richer and more dynamic today than when the boom began. A shakeout might be coming among renewable power players, and those that survive will strengthen their capabilities, hone their strategies, and take advantage of industry consolidation to build scale.

The remedy for America’s gravest economic woes may lie in a smart grid that can deliver vast amounts of clean, renewable energy while enhancing our energy security and democratizing our energy system. Although regulatory questions and technical challenges might dominate the industry’s short-term focus, the smart grid’s driving forces parallel America’s long-term national interests — a fact that should guide ongoing technology strategies and investment decisions.
