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.

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.

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.

Are the Feds at war with green power development? You might have thought so, if you had sat through the conference held March 15, 2011, at the Federal Energy Regulatory Commission, where the consensus seemed to be that FERC’s policy of granting open-access rights on electric transmission lines is problematic for green power projects. In short, when wind and solar developers choose to build their own local tie lines to link their projects to the larger grid, FERC policy forces them to make extra line capacity available to rival developers. That requirement doomed the novel Wind Spirit Project, and continues to complicate the job of project financing.

While it’s theoretically possible to keep the lights on with a much smaller reserve than the U.S. utility industry historically has maintained, the costs of doing so might be higher than some analyses suggest. As demand response plays a growing role on the grid—and as system planners reconsider reserve margins and reliability standards—quantitative risk analysis will guide resource adequacy decisions.

Generators and demand-response providers are reaping rewards in forward capacity auctions, causing suppliers to go shopping for the most lucrative markets. Now the Midwest ISO is trying to catch up, by proposing its own auction for years-ahead resource bids. But does RTO shopping serve the interests of customers, who are legally entitled to rates that are just and reasonable? Why are some state policy makers advocating a return to old-school RFPs for long-term contracts?

The case backlog of unprocessed electric reliability violations is growing out of control, threatening to “swamp” the industry — a sign, perhaps, that when Congress and FERC modernized the electric reliability regime to serve a more market-based industry structure, and for the first time gave enforcement authority to North American Reliability Corp. (NERC) as the nation’s official electric reliability czar, no one gave much thought, apparently, as to whether NERC’s very idea of what constitutes reliability might have needed modernizing as well.

Market rules could evolve to compensate gas suppliers for pressurizing pipelines when needed on short notice. Enhanced ancillary services will require innovative strategies using line pack in interstate pipelines and stepped up communication among gas and electric market participants to preserve reliability objectives in gas and electric markets.

Small coal-fired plants are particularly vulnerable to economic and environmental pressures, putting some plant owners in what seems like a no-win position. But an emerging option—biocoal from crop wastes—might give small coal units a new lease on life.
