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.

Four years ago, Congress made its wishes known: it tabbed the National Institute of Standards and Technology to develop a set of standards for the smart grid, and then instructed FERC, the Federal Energy Regulatory Commission “adopt” those standards, but only after finding a ”sufficient consensus,” and only “as may be necessary” to assure “functionality and interoperability.” Yet what is known is not necessarily clear. Who decides if consensus prevails? What does “interoperability” mean? Should FERC’s “necessary” finding extend to retail smart grid applications, arguably outside its purview? And the biggest dispute — must standards be mandatory? — finds PJM at odds with much of the utility industry.

A wave of coal-fired plant retirements presages a possible crisis in the New England market. As load-serving utilities in ISO New England become increasingly dependent on natural gas-fired capacity and large-scale renewable generators, the region might be forced to rely on expensive cost-of-service reliability contracts to keep the lights on. Stakeholders are considering alternative approaches to encouraging power plant development, including special rate incentives previously reserved for transmission projects. Paul J. Hibbard, former Massachusetts DPU chairman and now vice president with the Analysis Group, analyzes how resource constraints are blurring the lines between competitive markets and integrated resource planning in New England.

Despite the variable nature of the resource, wind can be managed so that it will not impair the reliability of a utility system. The Federal Energy Regulatory Commission proposed a rule that would require changes to the way transmission service is scheduled, which would enhance the ability of balancing authorities to integrate wind.

With budget battles heating up in Washington, Congress and the Obama administration are squaring off to debate energy policy legislation. While Democratic leadership favors a clean energy standard, Republican lawmakers are focused on blocking administration initiatives to regulate greenhouse gas emissions. A compromise approach might bring substantial changes to America’s national energy strategy.
