Tackling 111(d): Could Regional Approaches Rule?

By Ken Colburn
States have a long history of collaborating to achieve energy and environmental goals at lower cost and with greater efficiency than they could achieve alone. Collaborating to implement EPA’s forthcoming 111(d) rule may once again offer across-the-board benefits to the power sector, EPA, and the states themselves. Better for the Electric Power Sector Reli... Read More

Tackling 111(d): Where to Begin?

By Ken Colburn
Lately, it seems as if everyone associated with the power sector or an environmental organization is opining on whether EPA will allow this approach or that mechanism to count toward compliance in its proposal to regulate greenhouse gas (GHG) emissions from existing power plants under section 111(d) of the Clean Air Act (CAA). Rather than listening to these progn... Read More

RAP Profiles EU Member State Power Sectors

In a new series of reports commissioned by the Agora Energiewende, RAP is preparing high-level profiles of the electricity sector in several European Member States. The reports provide an expert summary of the structure of the electricity industry, regulatory framework, power markets, and policy and political developments in each of the Member States profiled. Th... Read More

PV Proliferation: Rays of Opportunity

By Richard Sedano
There are several ways to view the big changes underway in the US power sector. One is through the lens of the dramatic success of net metering. In 2003, before the Energy Policy Act of 2005 created a federal net metering standard, fewer than 7,000 customers in the entire country were net metered. By the end of 2011, less than ten years later, 43 states adopted n... Read More

Teach the Duck To Fly: Integrating Renewable Energy

An unlikely animal is the new face of renewable energy in the US. The “duck” curve illustrates the load shape some grid operators expect to contend with as increasing levels of wind and solar resources create ramping challenges for conventional generation. Join just about any industry conference or conversation about integrating renewables, and the duck s... Read More

Standby Rates for Combined Heat and Power Need a Fresh Look

Combined heat and power (CHP) installations offer industrial and commercial owners stable energy prices, lower overall energy costs, and reliable power during grid outages. Under some electricity rates, CHP customers face confusing and potentially contradictory tariff conditions, leading to excessive costs for the back-up electricity and grid services provided by...

Practical Solutions for Energy, Climate, and Air Quality in China

China’s power sector accounts for about a quarter of global coal consumption. The Chinese government’s economy-wide energy and environmental plans outlined in the 12th Five-Year Plan (2011–2015) and the new Air Pollution Prevention and Control Action Plan (2013–2017) call for large improvements in air quality and caps on coal consumption. Many polic... Read More

Energy Efficiency and the Energiewende

Although Energiewende policies focus primarily on the nuclear phase-out, ramping up the share of renewables in the power mix, and corresponding grid infrastructure needs, many people are looking for solutions to the “affordability” challenges of the Energiewende due to rising concerns over transition costs. Removing market barriers to energy efficiency and es... Read More

Increasing System Flexibility in Germany Through Demand Response

The Energiewende targets for increasing renewable energy resources in Germany to at least 50% by 2030 will require increased demand-side flexibility to ensure system reliability. Incorporating dispatchable demand response resources into the energy market can increase system flexibility and ensure reliability at lower cost. As described in RAP’s Demand Respons... Read More
