Utilities are testing options for adding solar capacity to existing steam power plants. Concentrated solar thermal boosters increase plant efficiency and reduce emissions, while helping utilities to cost-effectively meet renewable mandates.

Asset owners in the Northwest cry foul as the Bonneville Power Administration struggles to reconcile FERC orders with its operational realities. The battle between wind and water has blown up into a regional conflict over transmission tariffs.

In competitive power markets based on locational marginal pricing (LMP), the facts sometimes conflict with popular belief. Most notably: 1. When there’s congestion, the books don’t balance, and ratepayers always pay more than the generators receive. The difference is sometimes called “congestion cost.” 2. Congestion in a competitive market doesn’t necessarily increase ratepayers’ costs; and 3. Reductions in LMP are incomplete and sometimes misleading measures of economic benefits of transmission upgrades. These three facts and their implications should be considered in transmission planning, market design, tariffs, and system operations.

The EPA’s new method for measuring the amount of methane that escapes from natural gas wells is based on flawed data. Oklahoma’s attorney general says this misguided policy decision treads on state regulatory authority and stifles resource development.

(July 2012) Thanks for your enlightening editorial about the problems of feed-in tariffs for photovoltaic installations and the distortions they are causing in cost responsibilities among electric utility customers. While these issues are an immediate and growing concern, an entirely different set of problems will emerge over the next decade as the share of renewables in total generation approaches the high levels being dictated by most regulatory authorities.

Southern Company announced changes in the company’s management team. Great Plains Energy and Kansas City Power & Light (KCP&L) appointed Scott Heidtbrink as executive v.p. and COO of KCP&L and greater Missouri operations. NV Energy announced two senior leadership appointments. Pacific Gas & Electric (PG&E) appointed Jesus Soto Jr. as senior v.p. of gas transmission, operations, engineering, and pipeline integrity. And others...

A growing wave of rooftop PV projects is starting to look ominous to some utilities. Will lawmakers accept utilities’ warnings at face value—or will they suspect they’re crying wolf?
