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

Overcoming Barriers to Distributed Resources Through Education and Dialogue

The Mid-Atlantic Distributed Resources Initiative (MADRI) identifies and remedies retail barriers to the deployment of distributed generation, demand response, and energy efficiency in the Mid-Atlantic region. Consistent with RAP’s vision for a clean, flexible electricity system, MADRI is guided by the belief that distributed resources should compete on equ... Read More

Applying “Beyond Capacity Market” Thinking to Energiewende Reliability Challenges

At the heart of the challenge for the Energiewende will be to continuously balance consumer demand with fluctuating electricity production from variable renewable resources, such as wind and solar. This will require flexibility on both the supply side and the demand side. New thinking about market design and investment incentives for flexible capabilities, not ju... Read More

Making Germany’s “Energiewende” (Energy Transition) a Reality

Germany’s Energiewende represents a national commitment to meet aggressive economy-wide decarbonization targets and to transform the German power sector from a reliance on nuclear and coal to renewable resources within the next four decades. Germany is unique in the European Union in arriving at a consensus among ruling and opposition parties for a full nuc... Read More
