Are Solar and Wind Really Killing Coal, Nuclear and Grid Reliability?

           

Lessons from the Lone Star State: A surge in wind power on the Texas grid didn’t cause reliability problems (and brought down electricity prices) because regulators improved the efficiency of wholesale electricity markets. Sarah Fields Photography/Shutterstock.com

U.S. Secretary of Energy Rick Perry in April requested a study to assess the effect of renewable energy policies on nuclear and coal-fired power plants.

Some energy analysts responded with confusion, as the subject has been extensively studied by grid operators and the Department of Energy’s own national labs. Others were more critical, saying the intent of the review is to favor the use of nuclear and coal over renewable sources.

So, are wind and solar killing coal and nuclear? Yes, but not by themselves and not for the reasons most people think. Are wind and solar killing grid reliability? No, not where the grid’s technology and regulations have been modernized. In those places, overall grid operation has improved, not worsened.

Solar Experiment Lets Neighbors Trade Energy Among Themselves

 . . . In a promising experiment in an affluent swath of the borough, dozens of solar-panel arrays spread across rowhouse rooftops are wired into a growing network. Called the Brooklyn Microgrid, the project is signing up residents and businesses to a virtual trading platform that will allow solar-energy producers to sell excess-electricity credits from their systems to buyers in the group, who may live as close as next door.

The project is still in its early stages — it has just 50 participants thus far — but its implications could be far reaching.

Beyond simply contracting for solar, utilities are increasingly investing in the sector to ‘position themselves to be the utility of the future'

Solar energy is becoming a generation resource so ubiquitous that utilities are looking beyond simply contracting for new capacity and are increasingly moving into the sector themselves.

Solar added a record-breaking 14,762 MW of capacity in 2016, nearly doubling its 2015 growth. The resource added 39% of all new U.S. generation capacity in the year, making it the leader among all resources for the first time.

Growth was dominated by utility investment in 2016, a trend that’s expected to continue, according to a new report from the Solar Energy Industries Association and GTM Research.

Will a New Glass Battery Accelerate the End of Oil?

Electric car purchases have been on the rise lately, posting an estimated 60 percent growth rate last year. They’re poised for rapid adoption by 2022, when EVs are projected to cost the same as internal combustion cars. However, these estimates all presume the incumbent lithium-ion battery remains the go-to EV power source. So, when researchers this week at the University of Texas at Austin unveiled a new, promising lithium- or sodium-glass battery technology, it threatened to accelerate even rosy projections for battery-powered cars.

How California Utilities Are Managing Excess Solar Power

news.morningstar.com - by Cassandra Sweet - March 4, 2017

California utilities including PG&E Corp., Edison International and Sempra Energy are testing new ways to network solar panels, battery storage, two-way communication devices and software to create "virtual power plants" that manage green power and feed it into the power grid as needed.

The Golden State is ramping up renewable energy as it pledges to be a bulwark against the Trump administration's pro-fossil fuel policies. But first, it has to figure out what to do with all the excess power it generates when the sun is shining and the wind is blowing.

As rooftop solar costs drop, utility attempts to raise barriers may not work

tampabay.com - November 13th 2016 - Mary Ellen Klas

Florida's utility industry steered more than $20 million of their profits into a failed constitutional amendment to impose new barriers to the expansion of rooftop solar energy generation, but developers say that as the cost of installing solar panels drops, the state could quickly become a leader in private solar energy expansion no matter what the energy giants do.

The Florida Solar Energy Industry Association estimates that over the next five years, Florida homeowners, businesses and utilities are projected to take advantage of the falling prices and install 2,315 megawatts of solar electric capacity — 19 times more than the amount of solar installed in the last five years.

The myth of renewables threatening grid stability?

bnef.com - October 31st 2016

Germany’s power grid outage averaged 12.7 minutes last year, 41% less than in 2006, even though renewables have grown to account for as much as a third of power generation in the country, according to data released by the federal regulator last week.

This put to rest concerns about intermittent sources of power threatening grid stability. The country is weaning itself away from nuclear power and embracing renewables generation, providing a working model of transformation of the energy sector for many other countries.

Energy Secretary Moniz and Interior Secretary Jewell Announce New National Offshore Wind Strategy to Drive Deployment

CLICK HERE - NATIONAL OFFSHORE WIND STRATEGY: FACILITATING THE DEVELOPMENT OF THE OFFSHORE WIND INDUSTRY IN THE UNITED STATES

energy.gov - September 9, 2016

BOSTON - U.S. Secretary of Energy Ernest Moniz and U.S. Secretary of the Interior Sally Jewell today announced the publication of a collaborative strategic plan to continue accelerating the development of offshore wind energy in the United States, the National Offshore Wind Strategy: Facilitating the Development of the Offshore Wind Industry in the United States, which could help enable 86 gigawatts of offshore wind in the United States by 2050. The strategy details the current state of offshore wind in the United States, presents the actions and innovations needed to reduce deployment costs and timelines, and provides a roadmap to support the growth and success of the industry.

PG&E to close Diablo Canyon, California's last nuclear power plant

latimes.com - June 21st 2016 - Ivan Penn and Samantha Masunaga

One of California’s largest energy utilities took a bold step in the 21st century electricity revolution with an agreement to close its last operating nuclear plant and develop more solar, wind and other clean power technologies.

The decision announced Tuesday by Pacific Gas & Electric Co. to close its beleaguered Diablo Canyon nuclear plant within the next decade runs counter to the nuclear industry’s arguments that curbing carbon emissions and combating climate change require use of nuclear power, which generates the most electricity without harmful emissions.
