Wind and Solar Costs Continue to Drop Below Fossil Fuels. What Barriers Remain for a Low-Carbon Grid?

           

Energy Innovation's Michael O'Boyle and Silvio Marcacci outline the barriers to high-penetration wind and solar in the least-cost era

The following is a viewpoint from Michael O'Boyle, electricity policy manager for Energy Innovation, and Silvio Marcacci, communications director for Energy Innovation

Wind and solar are now cheaper than virtually anyone predicted, and renewable technologies have reached an inflection point: Rapid cost declines made renewable energy the cheapest available sources of new electricity, even without subsidies, in 2017.  In many locations across America, building new wind energy projects is cheaper than running existing coal-fired power plants.

Microgrids as Resilient Energy Infrastructure

           

Microgrid at Princeton University

utilitydive.com - March 20, 2018

The National Academy of Sciences defines “resilience” as the ability to prepare and plan for, absorb, recover from, and more successfully adapt to adverse events.  Since the September 2017 DOE NOPR to FERC, the energy industry has been working overtime to better define resilience.  FERC unanimously set aside the “90 days on-site fuel storage” provision espoused by DOE and opened a new docket (AD18-7) to more fully examine the current state of grid resiliency, asking the nation’s seven RTO’s and ISO’s to provide their definition of resiliency relative to the bulk power system by March 9.  Those ISO/RTO comments reflected regional variances as expected while sharing a common thread of the paradigm shift underway from central station power plants to more distributed generation . . .

Summary: The United States could reliably meet about 80 percent of its electricity demand with solar and wind power generation, according to scientists.

The United States could reliably meet about 80 percent of its electricity demand with solar and wind power generation, according to scientists at the University of California, Irvine; the California Institute of Technology; and the Carnegie Institution for Science.

Valuing the Resilience Provided by Solar and Battery Energy Storage Systems

submitted by John Cooper

                                     

cleanegroup.org

Summary:

Researchers from NREL and Clean Energy Group found that placing a monetary value on the ability of solar+storage to avoid losses during grid outages can significantly impact project economics and system design. Using data from Southern California Edison, researchers analyzed the economic case for solar+storage for three customer types (school, office building, and hotel) in Anaheim, California. In each case analyzed, larger PV and battery storage systems were found to be economical when the value of resilience is accounted for.

Puerto Rico Energy Commission Opens Docket on Microgrids and Distributed Generation

Puerto Rico Gov. Ricardo Rosselló Nevares testifying on Capitol Hill this week.

microgridknowledge.com - by Elisa Wood - November 17, 2017

Puerto Rico’s energy commission has opened a docket to investigate ways to encourage microgrids and distributed generation to build an energy system with more fortitude against hurricanes.

Island officials described the docket this week in testimony before the U.S. Senate Committee on Energy and Natural Resources. Half of the island’s population remains without power two months after Hurricane Maria’s strike.

Utilities companies won't let you sell your own solar power. Why not?

The electric utility sector is broken – but the transformation we need will be virtually impossible so long as a handful of wealthy elites are calling the shots

theguardian.com - by Kate Aronoff - August 1, 2017

A new report from the US-based Energy and Policy Institute last week found that investor-owned utilities have known about climate change for nearly 50 years – and done everything in their power to stop governments from doing anything about it.

From their commitment to toxic fuels to their corrosive influence on our democracy to their attempts to price-gouge ratepayers, it’s long past time to bring the reign of privately-owned electric utilities to an end.

Why are Californian Solar Firms Paying to Give Away Power?

bbc.com - June 29, 2017

California companies are generating so much solar power that firms in other states are getting paid to take it.

The state has been forced into the arrangement to "avoid overloading its own power lines", according to the Los Angeles Times.

The situation doesn't necessarily mean we are "throwing money away", says economist Severin Borenstein, a professor at UC Berkeley's Haas School of Business.

"But it probably is an indication that there are some serious problems in the way we're running the grid and the way we're making investment decisions."

A new quarterly report from the folks who brought you '50 States of Solar' aims to chronicle grid modernization initiatives across the US

utilitydive.com - by Herman K. Trabish - May 31, 2017

Grid modernization is a hot topic in the power sector as utilities across the country replace aging infrastructure and upgrade their systems for new energy technologies.

But until now, there was no easily-accessible tool to track the myriad regulatory actions on advanced metering, non-wire alternatives, ratemaking reform and the like.

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

theconversation.com - by Joshua D. Rhodes, Michael E. Webber, Thomas Deetjen and Todd Davidson - May 11, 2017

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.
