 . . . 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.

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.

This was supposed to be America’s nuclear century.

The Three Mile Island meltdown was two generations ago. Since then, engineers had developed innovative designs to avoid the kinds of failures that devastated Fukushima in Japan.

Threats to U.S. electrical grid are more sophisticated - Increase in smart grid technology increasing vulnerability

CLICK HERE - STUDY - Transforming the Nation’s Electricity System - The Second Installment of the Quadrennial Energy Review - January 2017

bloomberg.com - by Ari Natter and Mark Chediak - January 6, 2017

The U.S. Energy Department says the electricity system "faces imminent danger" from cyber-attacks, which are growing more frequent and sophisticated, but grid operators say they are already on top of the problem.

In the department’s landmark Quadrennial Energy Review, it warned that a widespread power outage caused by a cyber-attack could undermine "critical defense infrastructure" as well as much of the economy and place at risk the health and safety of millions of citizens.

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

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.

New York Unveils New Way to Price Distributed Energy Resources

microgridknowledge.com - October 28th 2016 - Elisa Wood

New York energy advisors unveiled a new, more granular way to price distributed energy resources and transition away from net metering, in a proposal released yesterday.

The report, issued by the Department of Public Services staff, said that current pricing methods fail to take into account the full value of distributed energy.

State regulators had called for the report as part of Reforming the Energy Vision (REV), New York’s strategy to create a decentralized power grid.

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.
