The Midwest Independent Transmission System Operator (MISO) on Thursday approved 215 new transmission infrastructure projects as part of the grid operator’s Transmission Expansion Plan 2011 (MTEP11). The projects include 17 transmission line projects that are estimated to cost as much as $5.2 billion to manage a “severe drop in planning reserve margins” that MISO has forecast could occur in the next years if pending environmental regulations proceed as planned.

An agreement reached between LS Power and environmental groups on Monday ends a decade-long legal battle, but it will force the company to ditch plans to build the 1,200-MW coal-fired Longleaf Energy Station near Blakey, Ga.; shelve plans for at least five years to build the 665-MW Plum Point II coal-fired plant near Osceola, Ark.; and limit pollution from the 900-MW pulverized Sandy Creek plant in Riesel, Texas.

Entergy Corp. last week agreed to divest and then merge its electric transmission business with the nation’s largest independent electric transmission company, ITC Holdings Corp. If the merger is completed, and ITC integrates Entergy’s 15,700 miles of interconnected transmission lines, that company could become one of the largest transmission companies in the U.S. with more than 30,000 miles of transmission lines from the Great Lakes to the Gulf Coast.

Toronto-based Bruce Power on Monday officially abandoned plans to build a new nuclear power plant in Alberta that has been under consideration by the company since 2007, saying it would instead focus investments on increasing reliability and safety at its existing Bruce Power nuclear generating station in Ontario.

The Federal Energy Regulatory Commission (FERC) last week ruled that the Bonneville Power Administration (BPA) discriminated against wind generators when it used its transmission market power to curtail wind power after high river flows and high wind last May and June caused generation on the BPA system to exceed power demand.

NRG Energy brought development of a key offshore wind project off the coast of Delaware to a screeching halt on Monday. Saying the development of a new domestic offshore industry was ridden with “monumental challenges,” the Princeton, N.J., company cited its inability to find an investment partner, a lack of federal loan guarantees, and the looming expiration of wind tax incentives as key reasons behind its decision.

A report released by the Government Accountability Office (GAO) last week finds that the Tennessee Valley Authority’s (TVA’s) financial condition could hamper its ability to fund capital improvements—including a 20-year plan to meet power demand with more natural gas generation, three new nuclear reactors, and expanding energy efficiency programs.

Vattenfall last week scrapped a much-awaited €1.5 billion ($2 billion) carbon capture and storage (CCS) demonstration project it planned to build and begin operating by 2015 in the German federal state of Brandenburg, blaming “insufficient will in German federal politics.”

Rules proposed by the U.S. Environmental Protection Agency (EPA) that could require operators of new and existing boilers burning coal, oil, natural gas, and biomass to install a “maximum achievable control technology (MACT)” and limit air pollutants were revised on Friday to offer more flexibility.

Days after the North American Electric Reliability Corporation (NERC) warned in a new assessment that new federal air quality rules could stress the nation’s power grid, the Department of Energy (DOE) released its own report examining the potential impact of two standards on electricity reliability. Those rules would prompt the closure of 29 GW of coal-fired capacity, but they should not create resource adequacy issues or unmanageable reliability challenges, the DOE finds.
