Sun Damage

Geomagnetic storms and the limits of human experience.

On April 30, FERC held a technical conference to review scientific claims and policy arguments about geomagnetic disturbances, known as GMD—how some say that a once-in-a-century solar storm could induce a power surge on the interstate grid so destructive as to cook and fry as many 300 extra-high-voltage transformers, plunging much of the nation into a blackout lasting months or even years. Some researchers even harbor fears that GMDs could end life as we know it.

Solar Screen Test

Making room on the local grid for small-scale PV.

For the first time, perhaps, the electric utility industry may need to keep track not only of peak load, but also of minimum load, as the Federal Energy Regulatory Commission reviews a proposal by the Solar Energy Industries Association to employ a new definition of minimum load under a new, relaxed threshold test that would govern eligibility for fast-tracking of applications by generation developers to interconnect new, small-scale solar energy projects to the local utility distribution grid.

Killing the Goose

Second thoughts on transmission’s golden egg.

The electric utility industry offers up a wealth of ideas on how the Federal Energy Regulatory Commission might reform its policy, adopted under FERC Order 679 in 2006, of granting financial incentives for investments in transmission line projects that ensure reliability or mitigate line congestion so as to reduce the cost of delivered power. Fortnightly’s Bruce W. Radford reports.

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.

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.

Open Access on Trial

The old rules don’t always fit with new commercial realities.

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.

Treading Water

Despite market turmoil, state commissions refuse calls for an ROE boost.

(November 2011) Our annual survey of rate cases shows that despite volatility in financial markets, state regulators are holding utilities to a high standard for boosting their returns on equity (ROE). The latest data is added to Fortnightly.com's exclusive online ROE survey database, the largest free source of rate case information anywhere on the Web.

Yes, We Have No Negawatts

When you sell demand response back to the grid, how much capacity are you now not buying?

When customers sell demand response into a regional capacity market (such as PJM’s Reliability Pricing Model, known as the RPM), how much credit should they earn for agreeing to curtail demand and alleviating stress on the grid — that is, for reducing the market’s need for generating capability and capacity reserve margin? And further, should the amount of credit depend on whether the customer works with market aggregators, known both as CSPs (“Curtailment Service Providers”) or ARCs (“Aggregators of Retail Customers”)? One view would pay customers for the full extent of their curtailment of demand — known as its “Guaranteed Load Drop” (GLD). The other would limit capacity credit to the customer’s prior load history — “Peak Load Contribution,” or PLC. The answer may well dictate whether regulators continue to treat “energy” and “capacity” as two distinct concepts.

Bonneville's Balancing Act

In the Pacific Northwest, you either spill water or spill wind.

The wind power industry has been up in arms ever since the Bonneville Power Administration earlier this year announced its Interim Environmental Redispatch and Negative Pricing Policy. That policy, applicable during periods of high spring runoff and heavy water flow volumes on the Federal Columbia River Power System, calls for BPA to redispatch and curtail access to transmission for wind power generating turbines, and to replace that resource with hydroelectric power generated via BOA hydroelectric dams, in order to avoid having to divert water through dam spillways, which could threaten fish and wildlife by creating excess levels of Total Dissolved Gas (TDG), which can cause Gas Bubble Trauma. Yet the legal issue remains unclear: Does this practice imply discrimination in the provision of transmission service, or is it simply a matter of system balancing and generation dispatch? In fact, the FERC may lack jurisdiction over the dispute, as it pertains to the fulfillment of BPA’s statutory mandates.

The NOPR Was Late

But transmission planning, as we know it, may never be the same.

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.
