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?
Has demand response hit an evolutionary dead end?
On March 18, the day after this issue went to press, FERC was scheduled at its decisional meeting to open a new formal inquiry on the role of demand response in regions that already have competitive wholesale power markets. In particular, how much money should grid operators pay to electric customers who promise not to buy wholesale power?
Siemens Energy has been awarded an 18-month, $300,000 R&D program by the Illinois Clean Coal Institute to study the effects of coal and coal-derived syngas combustion on the behavior of material and coating degradation in utility boiler and gas turbine environments. Focus areas of the research program will explore materials degradation modes in integrated gasification combined-cycle (IGCC) systems and utility boilers.
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.
A trio of eager tech startups confronts an industry intent on preserving the status quo.
In light of all the excitement created by smart-grid regulatory initiatives and stimulus funding, three clever tech startups have come forward with proposals for novel grid projects. In California, Western Grid Development proposes to install energy storage devices ranging in size from 10 to 50 MW at various discrete and strategic locations in PG&E’s service territory where the California ISO has identified reliability problems. Second, a company called Primary Power proposes to deploy a total of four advanced, 500-MVAR static VAR compensators (SVC) at three separate locations within the PJM footprint. Third, in Clovis, N.M., Tres Amigas plans to allow power producers to move market-relevant quantities of electric power and energy between and among the nation’s three asynchronous transmission grids: ERCOT and the Eastern and Western Interconnections.
Transforming DR and smart-grid policies into reality.
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.
Aligning renewable energy incentives with RPS compliance.
States’ green energy policies are being used to serve multiple agendas. Lawmakers should revisit their renewable incentive programs to better align them with policy goals. A regional approach will yield a more efficient portfolio.
The changing architecture of demand response in America.
Pilot projects are demonstrating the potential of smart metering and smart rates to make the most of supply and demand resources. But as empirical studies show, not all pricing designs are equally suited to every region.
