Local communities welcome new reactor projects.
Visitors to Waynesboro in northeast Georgia might be surprised at local residents’ opinions about two new nuclear energy plants planned for that site; namely, they’re giving the reactors a warm welcome.
Shaping long-term smart-grid strategy.
Making the business case for the smart grid is an important utility goal. It provides the justification for making or deferring required investments. Utilities might find it necessary to engage in a cycle of continuous strategic planning.
Forecasting brings wind energy under control.
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.
Has the one-day-in-10-years criterion outlived its usefulness?
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?
Living in the new world of mandatory reliability standards.
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.
Mitigating enforcement penalties in NERC hearings and appeals.
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.
Tools to facilitate changing utility economics.
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.
How merchant funding is remaking the rules for renewables.
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.
Strategies for surviving the industry’s transition.
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.
The most economical energy savings might be found in grid efficiency.
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.
