Unleashing Energy Efficiency

The Best Way to Comply with EPA’s Clean Power Plan

A framework for measuring the resource value of energy efficiency – touted as the best way for states to comply with the EPA’s Clean Power Plan.

Triggering & Tailoring

What the Supreme Court said, and didn’t.

Justice Scalia saw the need for tailoring as proof that EPA’s Triggering Rule was mistaken.

The Politics of Carbon

Supreme Court may ultimately clarify EPA’s authority under Clean Power Plan.

The Supreme Court questions federal agency authority over greenhouse gas emissions in the recent case of Utility Air Regulatory Group v. EPA.

Minnesota Power Finalizes Environmental Agreement with EPA

Minnesota Power, a utility division of ALLETE, reached a settlement agreement with the Environmental Protection Agency (EPA) and the Minnesota Pollution Control Agency that resolves alleged violations of the new source review provisions of the Clean Air Act. The agreement does not include any admission of wrongdoing on the part of the company Minnesota Power is one of many utility companies in the U.S. whose investments in electric generation facilities were reviewed as part of the EPA's Coal-Fired Power Plant Enforcement Initiative that began in 1999.

Complying with 111(d)

Exploring the cap-and-invest option.

EPA is expected to provide states with latitude in meeting Clean Air Act GHG standards. The Regional Greenhouse Gas Initiative (RGGI) demonstrates an effective and economical approach: “cap and invest.”

Putting a Price on Carbon

How EPA can establish a U.S. GHG Program for the Electricity Sector.

With the Environmental Protection Agency’s proposed greenhouse gas (GHG) emissions standards expected in June 2014, many states are considering their own approaches to provide flexibility in meeting compliance requirements. Experience in North America to date provides policy guidance.

Catching Fire

Climate policy heats up after the Great Recession.

GHG rules are coming soon. What happens next will depend on how states react.

Game Changers

State regulators address transformative forces.

In Fortnightly’s Regulators’ Roundtable, commissioners from Idaho, Illinois, and Minnesota consider transformative forces and the regulatory response.

Energy Disconnect

Misguided policies threaten resource adequacy.

Resource planning is grinding to a halt. From EPA regulations to irrational markets, today’s policy missteps threaten tomorrow’s reliability.

Montana Says Federal GHG Rules Prohibit New Coal Plants

The Montana Public Service Commission (PSC) told the U.S. Environmental Protection Agency (EPA) that it believes proposed rules restricting greenhouse gas emissions for new power plants would make it impracticable to construct any new coal-fired electric generation plant in the United States. The commission urged withdrawal of the EPA’s proposed carbon pollution standards under the Clean Air Act, noting that the EPA had recently delayed issuance of its draft New Source Performance Standards, first proposed in March 2012.
