New York's Natural Gas Path

The state is diverging from the national trend.

New York is taking its own path and outlawing the use of high-volume natural gas fracking. Yet, the state will remain a voracious consumer of natural gas that is fracked elsewhere. What gives?

Tennessee Valley Authority and DuPont to Continue Cogeneration Partnership at Johnsonville

The Tennessee Valley Authority (TVA) and DuPont partnered to generate power and steam at TVA's Johnsonville site in Humphreys County, Tenn. The two companies recently agreed on a plan to convert an existing, limited-use combustion turbine at Johnsonville into a highly efficient combined heat and power, or CHP, plant. With TVA retiring the last four coal-fired units at Johnsonville by the end of 2017 under its clean-air agreement with the Environmental Protection Agency, a new steam source had to be found.

Energy Politics are Combustible

Many in business back EPA, but the new Congress has yet to weigh in.

The comment period closes on EPA’s Clean Power Plan, but Congress is holding its cards close to the vest.

From Coal to Gas

Regulatory and environmental challenges for power plant conversions under the EPA’s Clean Power Plan.

Converting a power plant from coal to natural gas triggers a host of environmental challenges and regulatory issues. Operators could be trading one set of regulatory obligations, liabilities, and costs for another, equally problematic, set of liabilities and costs.

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.

EPA's Clean Power Plan: An Unequal Burden

The Clean Power Plan's largest obstacle is how its cost is distributed disproportionately among the states.

How the Clean Power Plan introduced in June by the Environmental Protection Agency will produce widely differing compliance obligations among the states, in terms of emissions targets, likely carbon prices, and effects on wholesale power prices.

Coal After MATS

A strategy for completely removing mercury from environmental emissions.

Coal-fired power plants subject to EPA’s MATS rule can try a biological treatment option to remove mercury emissions from the environment.

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.

Reliability vs. Resiliency

Prevent problems, or wait and respond when something happens?

FERC holds conference on electric reliability, asks about standards for resiliency – not just to prevent problems, but how to respond once they occur.

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.
