DR design flaws create perverse incentives.
Demand response isn’t energy: It’s a separate product, traded in a separate market. Policy trends, however, are moving toward equal treatment for demand and supply resources in electricity markets. Does treating DR as energy inflate its value and create perverse incentives?
Increasing renewable generation threatens reliability.
An increased reliance on renewable energy could threaten reliability of the nation’s electric transmission grids by reducing the rotational mass and rotational inertia of on-line turbine generators, thus, reducing the capability of generators to respond to drops in voltage frequency. In fact, data collected from 1994 to 2009 for the Eastern Interconnection already reveals a drop in the grid’s capability (as measured in megawatts) to stop a very rapid drop in frequency — such as a drop of a tenth of a cycle per second.
Synchronizing networks to bring green power to market.
In order to fully integrate wind and other dispersed sources of energy into the system, America’s patchwork transmission networks need to be more closely interconnected and synchronized. An advocate for the Tres Amigas merchant transmission project explains how the proposed facility will integrate the grid.
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.
Zhen Zhang and Matthew Stern
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.
Daniel E. Frank & Caileen N. Gamache
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.
