There are numerous ways to add flexibility to the grid

An excerpt from David Roberts, vox.com  There are numerous ways to add flexibility to the grid. In one direction, toward more local solutions, you can “intensify” the grid, adding more storage and other distributed energy technology, creating more microgrids, and bringing more demand under control so it can be shifted to meet variable supply. All these solutions allow existing grids to …

Colorado approves Xcel plan to retire coal, shift to renewables and storage. Xcel still plans to buy 383 MW of gas plants

Source: Catherine Morehouse, Utility Dive, Aug. 28, 2018,  Colorado’s Public Utility Commission (PUC) voted unanimously on Monday to give preliminary approval to Xcel Energy’s Clean Energy Plan, which would see the utility close 660 MW of coal-fired generation a decade earlier than scheduled and shift to renewable resources. Under the plan, Xcel will close units 1 and 2 at the Comanche …

Clean Heating and Cooling: Ground Source and Air Source Heat Pumps

Ground-Source Heat Pump Ground-source heat pump  (GSHP) — also referred to as geothermal heat pump — systems provide space heating and cooling, and, in some cases, hot water for residential and commercial buildings. The technology uses an indoor heat pump unit and a heat exchanging ground loop buried underground (or underwater) to transfer thermal energy between and among the ground …

In all clean electric California generation would only take 39% of the land area fossil fuels do today

Mark Jacobson on Clean Technica, 26 Aug 2018 SB 100, a bill now pending in the California legislature, would transition California to 100% zero-carbon, effectively all renewable, electricity by 2045. Our studies provide a way to do this for all energy sectors (electricity, transportation, heating/cooling, and industry). Robert Bryce, a Senior Fellow of the Manhattan Institute, a think tank that …

Investor-owned utilities in California forecast that by 2025, 85 percent will leave their systems for renewable energy through community choice aggregation

Microgrid Knowledge, Aug 2018 Quickly growing community choice aggregations (CCA) are expected to play a significant role in drawing 85 percent of customers away from California’s investor-owned utilities by 2025, according to a new report. Provided by Wang An Q/Shutterstock.com The community aggregation report was one of three on grid disruption released by Next 10, an organization with a goal of improving …

Clean energy portfolios are economically attractive alternatives new gas-fired power plants, beating operating costs of efficient gas-fired power plants. How do we maximally use least-cost portfolios of distributed energy resources (DERs) to complement traditional electric grid infrastructure or to defer or avoid investments in it?

How do we maximally use least-cost portfolios of distributed energy resources (DERs) to complement traditional electric grid infrastructure or to defer or avoid investments in it? These combinations, also known as clean energy portfolios (CEPs), consist of resources like utility-scale and distributed wind and solar generation, battery energy storage, energy efficiency, and demand-response technologies used in place of new power …
