Midwest ISO

Congestion on Trial

PJM and the crisis over FTR underfunding.

PJM’s latest crisis—the underfunding of financial transmission rights that we’ve seen over the last few years—pushes regulators right to the edge. How far do they trust wholesale power markets? Do they accept the idea, proven by a famous economist, that freely traded financial instruments can work just as well—better even—than firm, physical contract rights?

In PJM’s case, we are told, the problem occurs when too much negative congestion shows up in real-time balancing. But if congestion is bad, shouldn’t negative congestion be good?

No Fuel, No Power

Lessons from New England on electric-gas market coordination.

Despite the hype about cheap gas, pipeline constraints are creating new risks. New England’s wholesale power prices ran three times as high this past February compared to the same month in 2012.

A Pricey Peninsula

Michigan chafes over regional grid planning, providing a policy lesson for the feds.

High prices have turned Michigan against regional planning -- a possible foretaste of what to expect under FERC Order 1000.

RTO Tango

PJM and MISO ran from the altar once before. Now there’s talk of a shotgun wedding.

Utilities in the Midwest ISO want greater access to sell into PJM’s lucrative market. But that might require a virtual merger of the two RTOs — a move rejected seven years ago as too costly, and perhaps still impractical today.

The CAPX2020 Model: Part II

One of the most ambitious transmission projects in America today is CAPX2020. In this second of two exclusive interviews, Fortnightly's Spark talks with Teresa Mogensen, Xcel Energy’s vice president of transmission, about how the investor-owned utility collaborated with public-power utilities to develop a complex set of lines and a solid investment for shareholders.

FORTNIGHTLY  What’s Xcel Energy’s role in the CAPX2020 project, and how does it fit into the company’s overall transmission plan and resource plan?

MOGENSEN CAPX2020 is very important for Xcel and the region.

The CAPX2020 Model - Part I

One of the most ambitious transmission projects in America today is CAPX2020, a series of lines in Minnesota and surrounding states. In this first of two exclusive interviews, Fortnightly's Spark talks with Will Kaul, Great River Energy’s v.p. of transmission, about how the project managed to succeed where others have failed.

Recently electricity started flowing through a new power line between Monticello and St. Cloud, Minn. This 28-mile, 345-kV segment represents a major milestone for one reason: it’s the first wire to go live in the 700-mile CAPX2020 transmission venture.

Transmission's True Value

Adding up the benefits of infrastructure investments.

Allocating the costs of new transmission investments requires accurately assessing the value of those new lines, and identifying the primary beneficiaries. But formulaic approaches rely too much on the most easily quantified cost savings, and reject benefits that are dispersed across service areas—or that might change over the course of time. Brattle Group analysts J.P. Pfeifenberger and D. Hou explain that comprehensive valuation produces a more accurate picture.

Baghouse Bottleneck

EPA, mercury and electric reliability.

The energy industry has known for decades that federal regulators eventually would set rules under the Clean Air Act to govern emissions of mercury and other air toxics from coal-fired power plants. However, with the U.S. Environmental Protection Agency now having issued a final mercury rule, along with guidelines for possible extensions of the compliance deadline, utilities and power plant owners finally have a clear idea what they are up against. And the outlook isn't pretty. The challenge is to retrofit many hundreds of generating plants across the country--and all on the same three-year compliance schedule. Yet two wildcards remain in play: what deference the EPA will give to electric reliability needs, as it "consults" with the Federal Energy Regulatory Commission (FERC) and the North American Electric Reliability Council; and how effective FERC Chairman Jon Wellinghoff will be as Republican leadership in Congress works to derail the new rules.

Partners in Power

Complex problems call for collective measures.

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.

FERC's Full Plate

A look at issues facing the commission for the coming year.

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.
