Reducing transmission grid congestion with solar

RMI.org 22 Feb 2018 Distribution-scale solar avoids using the transmission grid because electricity is produced close to load. There is basically no use of transmission or transmission-level generation capacity. It’s like renting office space close to home, so that you can skip use of toll-road highways and limit yourself to local roads. You don’t use the toll road, and thus …

California regulators first to allow multiple revenue streams for energy storage. Also, Maryland Storage Tax Credit pays 30%

Feb. 13, 2018, Utility Dive The state has approved rules that increase the ways for energy storage systems to make money, for example, through frequency regulation, capacity or spinning reserve services.  The California Public Utilities Commission in mid-January became the first state regulator to issue revenue stacking rules for energy storage projects, but the rules could be more of a starting point …

Solar and batteries are edging out gas, and batteries are becoming bigger for Tesla too

Bloomberg, Feb 2018 Natural gas is getting edged out of power markets across the U.S. by two energy sources that, together, are proving to be an unbeatable mix: solar and batteries. In just the latest example, First Solar Inc. won a power contract to supply Arizona’s biggest utility when electricity demand on its system typically peaks, between 3 p.m. and 8 p.m. The panel …

Puerto Rico’s blackout, the largest in American history, explained: More than a million Americans are still without power in part because of the botched hurricane recovery

If customers can produce and store electricity more cost-effectively than utilities can deliver it, then the calculus of market structure change

If customers can produce and store electricity more cost-effectively than utilities can deliver it, then the calculus of market structure changes. Instead of granting monopolies to concentrate capital in a few hands to build large-scale power plants, the market instead needs a way for customers to transact with one another. It needs a reliable infrastructure manager to oversee a platform …

Game Over For Coal: Scientists Nail Down Pesky Perovskite Solar Cell Problem

February 1st, 2018 by Tina Casey on Clean Technica  Remember back when plastic was a new and exciting thing? That’s more or less where we are with that other p-word, perovskites. Legions of scientists around the world have been trying to tease a durable solar cell out of this optically-promising but fussy material, and it looks like a team from the National Renewable …
