Transmission

Among all of the investment priorities in the U.S. electric power industry, one stands out as having the greatest momentum: transmission. This is interesting because transmission is perhaps the most difficult type of power infrastructure to develop, and has been for decades. Editor Michael T. Burr talks with executives at Xcel Energy and Great River Energy to learn how the CAPX2020 consortium has managed to succeed where others failed.

From the Fukushima disaster and its repercussions, to the raging battle over new EPA regulations, 2011 was one of the most volatile years on record for the electric power business. Will 2012 be better or worse than 2011? Cost factors make this a great time to invest, but overhanging uncertainties might bring another year of fear.

Price-Responsive demand, EPA regulations, and merger policy will be on the agenda for the coming year as the Federal Energy Regulatory Commission works its way through the list of key cases that were pending at FERC as of January 2011.

A pair of myths is driving many investments today—i.e., America’s T&D system is falling apart, but the smart grid will save the day. A new MIT study reveals a more nuanced truth about reliability, efficiency, and plans for new technologies. The most effective policies and investments will focus on solving real problems and delivering tangible benefits.

To encourage billions of dollars of investment into America’s transmission grid over the next several decades, the Federal Energy Regulatory Commission (FERC) is restructuring its regulatory policies to bring market-based solutions into the framework for planning, construction, and operation of new transmission lines. The recent Order 1000 is the most dramatic example of this effort. But as FERC has learned before, one set of rules doesn’t serve the financial and commercial needs of all market participants.

Six years after Congress granted FERC “backstop” siting authority for electric transmission projects in the Energy Policy Act of 2005, the regulatory landscape is still evolving as a result of federal court decisions and new FERC orders. But despite a lack of certainty at the federal level, project sponsors have filed numerous applications at the state level for new transmission projects. Can these projects proceed without greater certainty at FERC?

New technologies—and new expectations—require taking a fresh look at the institutions and practices that have provided reliable electricity for the past century. Collective action is needed to define the key attributes of a future grid and then to take the more difficult next step—adapting our processes and institutions to align with that future vision. A thoughtful approach will allow America to capture the potential value that’s offered by sweeping changes in technologies and policies.

The recent landmark ruling on transmission planning cost allocation, known as “Order 1000,” and issued by the U.S. Federal Energy Regulatory Commission in late July 2011, could well produce an unintended side effect — the formation of regional compacts among states to identify needs and plan for development of new power plant projects.

Smart grid technologies bring a host of cyber security considerations that need to be addressed throughout the T&D domain—and even into the customer’s home. In this exclusive report, Department of Energy authors team up with industry experts to examine how to deal with the changes and challenges of securing the smart grid.

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.
