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 …

Solar is now the cheapest source of bulk electricity in most sunny countries. We don’t need a technology breakthrough or subsidies to achieve massive adoption — just a grid connection and/or permission to sell electricity

Oct 2020: We’ll see solar & wind farms with capacity much larger than the grid connection, some with batteries…Solar curtailment is a feature not a bug. Solar’s probably the easiest source of generation to curtail quickly, so can really contribute to grid stability. And sometimes curtailment is a price worth paying for using a grid connection more fully. Hydrogen is …

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 …

Renewables are more reliable and offer more resiliency

Huffington Post: https://www.huffpost.com/entry/renewables-clean-energy-climate-disasters_n_5fad67d1c5b6cae94043c56b Wind and solar installations, while certainly not invulnerable, are less likely to be completely wiped out by extreme weather and can free people from reliance on a centralized source of power. Solar panels and wind turbines are effectively mini power plants in themselves, distributed across the landscape and able to be disconnected from the central grid, meaning that …

Idaho utility’s coal exit sparks NIMBY grid fight

Miranda Willson, E&E News, Nov 30, 2020 The interior of the Boardman Power Plant in Oregon, one of three coal plants from which Idaho Power previously sourced energy, is pictured. Idaho Power will stop burning coal by 2030 and plans to build a power line to bring new electricity sources to its service area. Ninjanabe/Wikipedia Following the moves of other electricity …

How Sweden Is Transforming Homes Into Power Stations

One example is in the city of Ludivika where 1970s flats have recently been retrofitted with the latest smart energy technology. 48 family apartments spread across 3 buildings have been given photovoltaic solar panels, thermal energy storage and heat pump systems. A micro energy grid connects it all, and helps charge electric cars overnight. The result is a cluster of ‘prosumer’ …

What is Transactive Energy and Why is it Important to Microgrids?

June 23, 2020 By Lisa Cohn The growing emphasis on using microgrids to generate revenue is leading to increased discussion of transactive energy…. The Monash paper, “Transactive Energy Market for Energy Management in Microgrids: The Monash Microgrid Case Study,” offers by way of example a microgrid being developed at the Australian university consisting of 20 buildings — a load of 3.5 MW …
