Reliability

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.

(March 2011) TVA and EPRI demonstrate solar-assisted EV charging station; Ford unveils the all-electric Focus; Central Maine Power awards substation contracts; ERCOT deploys ABB software in nodal market; FirstSolar starts up PV plant for Southern Company and Ted Turner; plus contracts and announcements involving Open Systems International, Verizon, Suntech Power, Alcatel-Lucent, Siemens, Cisco, Elster, Sensus, Silver Spring Networks and others.

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.

Policy makers in the E.U. and the United States are taking different approaches to facilitating smart grid development. While both regions are setting standards that the rest of the world likely will follow, they also face difficult challenges in resolving issues around cost recovery, customer engagement and workforce preparedness.

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?

New Jersey Gov. Chris Christie in February signed into law a bill that will have the state commissioning construction of 2,000 MW of new gas-fired power capacity and dumping it into the PJM capacity market at a $0 price. Maryland is considering a similar capacity-dumping scheme. What’s behind these efforts to manipulate capacity auctions — regional constraints or local politics?

Smart grid is a global phenomenon, but different countries are taking different approaches—for different reasons. For instance, utilities in Europe are more focused on laying the foundation for distributed generation and microgrids, while the United States is more concerned about creating standards for interoperability and security. Understanding the differences can help decision makers deploy smart grid technology effectively and economically.

Customer value is a key factor in any smart grid business case. But not all customers are created equal. In particular, commercial and industrial (C&I) customers have greatly different needs, considerations and sensitivities, compared to residential customers. As a result, demand response and efficiency programs won’t produce the same results across customer classes. Getting the most from the C&I market will depend on integrating smart grid with smart building technologies.

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.
