Advancements in forecasting have improved the reliability of day-ahead and hour-ahead estimates of wind generation. Wind never will behave like a base-load power plant. But as system operators integrate wind forecasts into their planning and market processes, they’re transforming intermittent wind energy into a variable but reliable resource.

The one-day-in-10-years criterion might have lost its usefulness in today’s energy markets. The criterion is highly conservative when used in calculating reserve margins for reliability. Can the industry continue justifying the high cost of overbuilding?

Mandatory reliability standards put in place by NERC three years ago give reason for optimism concerning their success. But the organization struggles with standards development, compliance, enforcement and transparency.

The North American Electric Reliability Corp. (NERC) holds substantial enforcement powers as the nation’s electric reliability organization for bulk power transactions. Taking affirmative steps will help utilities and system operators to avoid or minimize NERC penalties.

These are challenging times for the electric and gas utilities. Reliability projects, renewable portfolio standards, greenhouse-gas emissions control, AMI, smart-grid investments, and conservation programs—all these things add to costs, but might bring in no additional revenue. Moreover, there will be unprecedented capital investment in transmission, renewable generation projects, and replacement of old facilities from the 1950s and 1960s. Thus, earnings likely will be more closely watched and traditional general rate cases might not be able to keep up.

Six weeks ago, FERC opened a notice of inquiry to invite industry comments on whether wind, solar, and other intermittent energy sources face unfair obstacles in wholesale power markets. Now assigned their own acronym—VERs, for “variable energy resources”—renewables make up a growing percentage of the nation’s energy supply portfolio. But as FERC notes, they present “unique challenges,” especially in terms of constraints on location and limits on the degree to which system operators can control or dispatch individual VER units. Thus, FERC suggests that certain common rules and practices, such as those for unit commitment, dispatch, and scheduling, might make it overly difficult to integrate VERs into the grid.

To realize the full potential of smart-grid benefits, utilities must undergo significant changes. They must learn to integrate information and operations differently, demonstrate adaptability and modify cultural tendencies.

Power delivery efficiency gains constitute a valuable utility asset that can offset or defer new generation and T&D investments. Enabling technologies, utility demonstration projects and supporting regulatory frameworks are needed to validate potential savings.

Regulatory policies are evolving to make demand response and smart-grid planning a reality across the country. Cooperation between federal and state lawmakers will allow local flexibility within a uniform national framework.

The U.S. power market consistently has displayed cyclical characteristics of boom and bust over the last two decades. Today’s market environment has been directly and significantly impacted by the recent economic recession. Decreases in load growth, declining commodity prices, and lack of accessible financing have caused challenges for the industry.
