Electric transmission and distribution fees have jumped about 50% in the last decade. Microgrids are changing the way electricity is made, delivered, and used.

June 8, 2021 By Ethan Howland, Microgrid Knowledge Microgrids — managed by sophisticated software — are part of a shift toward on-site power production, driven by businesses and organizations that want to control their own energy destiny, according to a group of panelists at the Microgrid 2021 conference. Growth in microgrids comes as customers increasingly look for solutions to various issues, such …

When VRE and storage are allowed to provide operating reserves, system-wide operating costs and curtailment levels decrease

June 2021 webinar – New research on the curtailment paradox—the surprising relationship between system flexibility and curtailment in high solar futures.  The Curtailment Paradox in a High Solar Future: NREL Study Uncovers Counterintuitive Relationship Between Flexibility Options and Curtailment in Power Systems with High Solar Penetration, April 28, 2021 Rising penetrations of variable renewable energy (VRE) in power systems are expected …

The cleanest, lowest cost grid has 273 GW of local solar plus storage, providing $453 billion in savings, and over 2 million jobs. 798 GW of utility-scale solar and 802 GW of utility-scale wind needed by 2050

NREL Marks Ongoing Cost Reductions for Installed Photovoltaic Systems, While Also Establishing Benchmark of PV-Plus-Storage Systems in U.S. Solar Photovoltaic System and Energy Storage Cost Benchmark: Q1 2020. This year’s study also This year’s benchmark report integrates PV-plus-storage costs, demonstrating that these also fell from the first quarter of 2019 to the first quarter of 2020. The new benchmark includes …

Vermont’s home batteries take on gas power plants

Canary Media, 24 May 2021 Grid futurists anticipate a world where small-scale energy equipment scattered across homes and businesses usurps the fossil-fueled, capital-intensive plants that currently run the grid. To make this happen, all those devices need to operate as reliably as today’s centralized, utility-run infrastructure. That’s not easy, and not guaranteed. But Vermont utility Green Mountain Power just proved …

Batteries double CO2 savings of households with PV systems: PV reduces electricity CO2 emissions by 45% and by up to 85% with batteries

FEBRUARY 26, 2021 PETRA HANNEN from pv magazine Germany Photovoltaic systems for single-family homes reduce electricity-related CO2 emissions of the households by 45%, according to EUPD Research. When a battery is added the CO2 emissions can be reduced by up to 85%. RESIDENTIAL PV GERMANY https://www.pv-magazine.com/2021/02/26/batteries-double-co2-savings-of-households-with-pv-systems/ Good for the climate: a photovoltaic system.

California’s Plan: Crowdsource Distributed Energy to Replace Grid Upgrades

The Partnership Pilot could start to enroll solar, batteries, EVs and other behind-the-meter assets as non-wires alternatives later this year. By Jeff St. John, GreenTechMedia, Feb 5, 2021 California regulators are planning a new approach to enlisting behind-the-meter batteries, solar, electric vehicles and other assets to replace grid upgrades. 1 California’s investor-owned utilities have argued against this approach. In comments …

A regulatory roadmap for Vehicle Grid Integration

SEPA, Dec 2020 As EV deployment expands, Vehicle Grid Integration will be essential toproviding benefits for all customers while avoiding unintended consequences. While EV penetration is currently low in much of the country, we know that the day is coming (and in areas of high penetration, may have already arrived) when a more sophisticated approach such as VGI will be …

How big utilities are impeding clean energy and what we can do about it

Let’s Talk About Solar, Equity, and Monopoly Power in 2021, by JOHN FARRELL | DATE: 22 DEC 2020 |  Since ILSR wrote about the Dawning of Solar Cells (pdf) in 1975, we’ve been fans of the potential to integrate energy production with the local economy. We provided early forecasts of the rooftop solar revolution and support for the first statewide value of solar policy. Recently, we analyzed how distributed solar …

States and PUCs requiring energy storage

Nov 2020 – https://www.energy-storage.news/blogs/what-the-us-energy-storage-industry-could-look-like-under-biden-harris Even in the midst of COVID19, this year has seen considerable state action on the clean energy front, both through the state public utility commissions, and with legislation. Arizona’s Corporation Commission voted earlier in November to advance rules that include a five percent of peak load energy storage target. Maryland’s Public Service Commission approved a number of energy storage pilot projects that each demonstrate multiple use and ownership models of energy storage. …

Road to lowest cost grid is paved with distributed solar+storage: 247 GW of local rooftop and community solar and 160 GW of local energy storage is most cost-effective path. Local solar can power 25% of US homes

What would the grid look like, and cost, if we stopped ignoring the benefits of DERs and optimized the integration of these resources through a better modeling process? We found that when you use better planning models and scale both local solar and storage, as well as utility-scale solar and wind, you maximize cost savings and unlock the path to …
