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.

The Trouble with Freeriders

The debate about freeridership in energy efficiency isn’t wrong, but it is wrongheaded.

In any conservation or efficiency program, some market participants will reap benefits without paying their share of the costs—i.e., the “freerider” problem. Some freeriders are unavoidable and generally not a problem. But as Cadmus Group analysts Hossein Haeri and M. Sami Khawaja explain, avoiding excessive freeridership requires careful program structuring, as well as ongoing measurement to accurately evaluate outcomes.

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.

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.

Green Gridworks

Case studies on integrating renewable resources.

Where wind integration has been most successful, state authorities developed and adopted basic transmission planning and cost allocation principles before FERC issued Order 1000. Experiences in Texas, California, and Hawaii demonstrate what it takes to overcome permitting and cost allocation barriers—namely, a coherent policy framework and close coordination among stakeholders.

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.

Frequency Regulation

In a recent order, the Federal Energy Regulatory Commission (FERC) said that by paying the wrong price for the ancillary service known as frequency “regulation,” system operators have encouraged too many gas-fired turbines and other conventional fossil power plants to supply regulation service.

Putting market economics ahead of reliability, the Federal Energy Regulatory Commission (FERC) has told regional transmission organizations (RTOs) and other grid system operators (ISOs) to rethink the prices they pay for the ancillary service known as frequency “regulation.”

In short, FERC wants all power plants to do what they do best — recognizing that some may be well adapted to providing regulation service, but others perhaps not.

Trusting Capacity Markets

Does the lack of long-term pricing undermine the financing of new power plants?

The PJM Interconnect’s Reliability Pricing Model generally has succeeded in attracting and retaining low-cost generation and demand resources to maintain resource adequacy. But sluggish demand and low prices have weakened the market for long-term capacity contracts. Suppliers aren’t willing to lock in current low prices, and buyers don’t want to pay more for future certainty. Is the market dysfunctional, as some state lawmakers suggest, or does the lack of long-term contracts indicate a rational balance of supply and demand?
