World’s largest li-ion battery and 707 MW of solar power in Colorado proposal

Xcel Energy’s 120-day report to Colorado regulators includes an additional 1.1 GW of wind at 1.1-1.8¢/kWh. Solar power bids have come in at 2.2-2.7¢/kWh, and solar+storage at 3.0-3.2¢/kWh. June 7, 2018John WeaverBack in the quaint days of late 2017, the world was awoke by a batch of bids of momentous size – and shockingly low pricing – in a solicitation by Xcel Energy. In fact, the median bid on 16 GW of solar+storage came in at only 3.6¢ per kilowatt-hour (kWh). This price was only 0.65¢/kWh more than the 30 GW of solar-only bids. For perspective’s purpose – according to…

SDG&E to build 334 MWh of energy storage to support renewables

San Diego Gas & Electric has received approval by the CPUC for five energy storage projects totaling 83.5 MW of instantaneous power output, with a four hour rating. June 6, 2018John Weaver Fluence Energy StorageAs of the filing of the 2017 California RPS Annual Report, San Diego Gas & Electric (SDG&E) was already getting 43% of its electricity from renewable resources. The state expects to hit 50% renewables by 2020 – a full ten years ahead of the state’s 2030 target.In order to better maximize the intermittent nature of solar power and to meet state energy storage guidelines, SDG&E has is…

Residential energy storage grows 9x in Q1 2018

The 36 megawatt-hours of residential energy storage installed in the United States during Q1 is the latest in a year of accelerating growth rates, driven by policies in California and Hawaii. June 6, 2018John WeaverAs reported by EnergySage, 74% of residential solar power customers have an interest in energy storage. And while one can always debate whether expressing interest in a poll will ever turn into actual money being spent, this is not the only data point. In May, Arizona’s Salt River Project Water and Power launched a residential energy storage incentive with 4,500 spots available. With only one month elapsed…

Residential time of use pilot program coming to Minnesota

A two-year pilot program will be rolled out to roughly 10,000 Xcel Energy residential customers in early 2020. June 5, 2018John WeaverThe Minnesota Public Utilities Commission has approved a time of use (TOU) pilot for approximately 10,000 residential customers of Xcel energy, starting in 2020.The program will define a peak demand period from 3 PM until 8 PM. During weekdays and during this period, the price of electricity will be 92% higher than the standard rate. Simultaneously the ‘off peak’ rate – 12 AM till 6 AM, will be 54% lower than the standard rate.This means the peak afternoon/evening weekday…

Tesla and Panasonic to kill cobalt curse

Panasonic announced an aim to produce batteries for Tesla without using cobalt, much of which is sourced from the unstable and conflict-ridden Congo. June 5, 2018John WeaverOnly a few years ago, there were popular predictions that we would run out of oil, whereas today it, appears more likely that oil markets will suffer from peak demand, not supply. Similar arguments about resource scarcity have surfaced widely in anti-renewable propaganda, with concerns expressed about rare earths, lithium and other materials as easily debunked reasons why solar, wind and energy storage cannot scale.Some of these concerns could have been valid, were it…

LG Neon Bifacial spec page – 500W on a white membrane roof!

This spec page has been out for a bit, but this is the first I've seen it. This seems a utility scale panel versus standard commercial - note the 1500V notation, but the bifacial information is probably applicable to a residential or any other version panel. Notice that, in some wonderful perfect world, you can get a 25.4% output boost. I really want to get a database of roofing companies that have installed white roofs, so I can call on the customers.
