Berkeley Lab Examines State-level Renewables Portfolio Standards Policies

15.04.2008
Renewable electricity is being supported by a growing number of states through the creation of renewables portfolio standards (RPS). A report released by the U.S. Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) provides a comprehensive overview of the early experiences with these state-level RPS policies.
“State RPS policies require utilities to buy a certain amount of renewable energy, and these programs have emerged as one of the most important drivers of renewable energy deployment in the U.S.,” notes Ryan Wiser, of Berkeley Lab’s Environmental Energy Technologies Division (EETD), who was one of two primary authors for this report. “But, as the popularity and importance of these RPS’s have increased, so too has the need to keep up with the design, early experience, and projected impacts of these programs. Our report is designed to meet that need.”

Collectively, the RPS policies that are in place today in 25 states and Washington D.C., apply to nearly 50-percent of total U.S. electricity load. In addition, four new states joined the RPS roster in 2007.

“Many of these policies have been established recently and each is designed differently,” says Galen Barbose, the report’s other primary author and also a member of Berkeley Lab’s EETD. “As a result, the experience has been decidedly mixed.”

Some of the key findings of the study include:

More than 50-percent of non-hydro renewable capacity additions in the U.S. from 1998 through 2007 occurred in states with RPS policies, and 93-percent of these additions came from wind power.

Existing state RPS policies, if fully achieved, would require roughly 60 GW of new renewable capacity by 2025, equivalent to 15-percent of projected electricity demand growth.

Solar set-asides in state RPS policies are becoming more common, and these policies have supported more than 165 MW of new solar capacity so far; a total of roughly 6,700 MW of solar capacity would be needed by 2025 to fully meet these set-asides.

The early-year renewable energy purchase targets in the majority of state RPS policies have been fully or almost-fully achieved, with overall average compliance at 94-percent in 2006.

Nonetheless, a number of states have struggled to meet even their early-year RPS targets, and many states have been reluctant to penalize non-compliance.

Renewable energy certificate (REC) tracking systems continue to expand, and all but four states allow unbundled RECs to count towards RPS compliance.

The cost of RPS policies varies by state, but in most states, these programs have, so far, increased electricity rates by one-percent or less; in several states, the renewable electricity required by RPS policies appears competitive with fossil generation.

The market for renewable energy is changing rapidly, and states are increasingly hoping to support that growth. “Given the major role that state RPS policies are playing, we hope that this report will help improve the next generation of these programs,” concludes Wiser.

Berkeley Lab’s contributions to this report were funded by the Office of Energy Efficiency and Renewable Energy and by the Office of Electricity Delivery and Energy Reliability of the U.S. Department of Energy.

Berkeley Lab is a U.S. Department of Energy national laboratory located in Berkeley, California. It conducts unclassified scientific research and is managed by the University of California.

Im Focus: A “cosmic snake” reveals the structure of remote galaxies

The formation of stars in distant galaxies is still largely unexplored. For the first time, astron-omers at the University of Geneva have now been able to closely observe a star system six billion light-years away. In doing so, they are confirming earlier simulations made by the University of Zurich. One special effect is made possible by the multiple reflections of images that run through the cosmos like a snake.

Today, astronomers have a pretty accurate idea of how stars were formed in the recent cosmic past. But do these laws also apply to older galaxies? For around a...

Im Focus: Visual intelligence is not the same as IQ

Just because someone is smart and well-motivated doesn't mean he or she can learn the visual skills needed to excel at tasks like matching fingerprints, interpreting medical X-rays, keeping track of aircraft on radar displays or forensic face matching.

That is the implication of a new study which shows for the first time that there is a broad range of differences in people's visual ability and that these...

Im Focus: Novel Nano-CT device creates high-resolution 3D-X-rays of tiny velvet worm legs

Computer Tomography (CT) is a standard procedure in hospitals, but so far, the technology has not been suitable for imaging extremely small objects. In PNAS, a team from the Technical University of Munich (TUM) describes a Nano-CT device that creates three-dimensional x-ray images at resolutions up to 100 nanometers. The first test application: Together with colleagues from the University of Kassel and Helmholtz-Zentrum Geesthacht the researchers analyzed the locomotory system of a velvet worm.

During a CT analysis, the object under investigation is x-rayed and a detector measures the respective amount of radiation absorbed from various angles....

Im Focus: Researchers Develop Data Bus for Quantum Computer

The quantum world is fragile; error correction codes are needed to protect the information stored in a quantum object from the deteriorating effects of noise. Quantum physicists in Innsbruck have developed a protocol to pass quantum information between differently encoded building blocks of a future quantum computer, such as processors and memories. Scientists may use this protocol in the future to build a data bus for quantum computers. The researchers have published their work in the journal Nature Communications.

Future quantum computers will be able to solve problems where conventional computers fail today. We are still far away from any large-scale implementation,...
