Middle Mile Moxie

Xcel Energy proposes to create America’s first fully functional intelligent grid, with communications and automation systems linking the network from end to end, power plants to meters. Although Xcel still is deploying the system, it’s shown that the early payoff from smart-grid investments won’t necessarily come from automated metering, but from automation in the distribution network—the “middle mile.” As chief architect of the Smart Grid City project in Boulder, Colo., Ray Gogel served on the front lines in the industry’s technology revolution.

New York Negawatts

Balancing risks and opportunities in efficiency investments.

In June 2008, the New York Public Service Commission (PSC) established the electric energy-efficiency portfolio standards for New York’s investor-owned utilities. In its order, the PSC directed utilities to file three-year energy-efficiency plans. Later that year, the PSC issued a supplemental order approving shareholder incentives for utilities successfully implementing their portfolios. If all goes according to plan, the six affected IOUs stand to earn about $27 million annually in performance incentives over three years. The structure of the incentive mechanism approved by the PSC presents risk factors that might affect utilities’ ability to realize the full earning potentials the mechanism offers.

Wellinghoff's War

FERC fights for the green-grid superhighway—even if Congress won’t.

The Senate’s deadlock over carbon cap-and-trade legislation has not deterred FERC Chairman Jon Wellinghoff from an agenda bent on promoting renewable energy and fighting climate change. Last fall, even as Congress dithered, FERC launched a landmark initiative that likely will lead to sweeping new rules for expanding the nation’s electric transmission grid, grounded on Wellinghoff’s belief in wind, solar, and green power resources.

LMP Works!

Locational marginal prices in PJM respond to demand and fuel costs.

The evolution of real-time locational marginal prices (LMP) in PJM Interconnection’s wholesale electricity markets demonstrates the characteristics of a well functioning and competitive market; prices are driven by supply and demand fundamentals. Although critics of wholesale electricity markets frequently have pointed to increases in LMP as proof that the wholesale markets aren’t working, in reality, the markets are working as they should. Increases in LMP are driven by higher demand for electricity or increasing fuel prices.
