GWh-scale liquid-air battery offers storage at half cost of lithium, Recharge News
A UK technology company has unveiled a “cryogenic” energy storage system that it says can store gigawatt-hours (GWh) of renewable energy at half the cost of lithium-ion batteries. Highview Power says its scaleable zero-emissions CRYOBattery technology, which uses liquid air as its storage medium, could potentially replace natural-gas peaker plants that help to balance the grid. A 10-hour, 200MW/1.2GWh system offers a levelized cost of storage of $140/MWh, the company says. By comparison, analyst Lazard puts the price of a similar lithium-ion gas-peaker replacement facility at $285-581 per MWh.

South Sioux City to add 1.5MW battery to store solar power

By Mason Dockter, Sioux City Journal

SOUTH SIOUX CITY — The city of South Sioux City will become a “demonstration site” for the storage of electric power generated by the city’s 1,200-panel solar installation. A large-scale battery with the capacity to store 1.5 megawatts of power will be installed by Florida-based NextEra Energy Inc. this winter, City Administrator Lance Hedquist said.

The unit carries a price tag of about $1.8 million, but Hedquist said the cost will be whittled down by state funds and tax credits. He said the battery will probably have the appearance “of a semi trailer without wheels,” and will be located by the city’s 21-acre, 2.3 megawatt solar panel site . . . Hedquist has said the city plans to fully phase out of its wholesale power contract with NPPD by 2020. Read more here.

Dawson Public Power proud to be publicly owned

By Brian Neben, Lexington Clipper-Herald

LEXINGTON — Nebraska is the only state to be served entirely by public power and the Dawson Public Power District is proud of this fact and to serve their region of Central Nebraska. Dawson Public Power District, DPPD, held their annual customer tour of their facility south of Lexington on Tuesday, June 25. During the tour DPPD electrical services and policies were explained, safety demonstrations held and people could ask questions about public power. “An informed customer is our greatest asset,” said DPPD general manager Gwen Kautz. DPPD was organized in February 1937 as a part of the Rural Electrification Act passed by President Franklin Roosevelt as part of an effort to electrify rural farmsteads.

Looking to the future Kautz said “renewable energy is late coming to Nebraska, but it is coming and it will grow.” Changes will have to be made to the grid as wind, solar, batteries and stored hydro become more prevalent and traditional sources like coal, nuclear and natural gas are slowly phased out. “I predict the marriage of solar power to storable batteries will take over for the traditional energy sources,” said Kautz. She said 10 years ago she doubted the impact of renewable energy, today she has rethought that position. Read more here.

Sol Systems Photo: In 2017, Sol Systems and GenPro Energy Solutions partnered with the City of Lexington to develop, finance, and construct a 3.9 MW solar farm. The array produces enough energy to power 700 homes each year. By locking into a Power Purchase Agreement (PPA), the City of Lexington will have 25 years of price certainty against volatile wholesale electricity rates.

Tesla signs on to utility’s peak shaving program, American Public Power Association
National Grid recently signed Tesla on to programs in Massachusetts and Rhode Island that use batteries to reduce the utility’s peak loads. Falling battery costs and declining net metering incentives have resulted in a rise in pairing the two technologies. In addition, there are several financial incentives available for pairing batteries with solar systems, including the Federal Solar Investment Tax Credit and the Solar Massachusetts Renewable Target (SMART) program. A February report from consulting firm Wood Mackenzie Power & Renewables projected that 50% of annual storage deployments in the United States will be paired with solar power by 2023.

Senate Bill Would Set Nation on Course for 50 Percent Renewable Energy or More by 2035

Environmental Working Group News Release

Currently, 30 states have renewables standards that require utilities to generate a set percentage of electricity that ramps up from year to year. The Renewable Electricity Standard Act, by Sen. Tom Udall (D-N.M), would require the remaining 20 states without renewables standards to get on board. A number of states with enormous solar and wind generation potential, like Florida, Georgia, Nebraska and Wyoming, have so far not adopted renewables policies. The proposal would more than double the pace of solar and wind development seen over the past decade, according to an analysis of Udall’s legislation by researchers with the Union of Concerned Scientists, or UCS.

The city’s two-year-old solar park provides roughly 5 percent of the city’s 45 megawatt electricity usage. That electricity costs roughly two-thirds the cost of electricity purchased from elsewhere, Hedquist said. Hedquist has said the city plans to fully phase out of its wholesale power contract with NPPD by 2020. Read more here.

Drinking Buddies: How to pair a beer with your next solar farm (and why)

By Chris Crowell, Solar Builder

So, a solar developer and a beekeeper walk into a craft brewery … have you heard this one before? No? Then you need to chat with Rob Davis. He’s the director of the Center for Pollinators in Energy at Fresh Energy, a non-profit that promotes better vegetation on solar farms and pulls together partnerships to include bee apiaries as well.

“Whenever a solar farm is built on arable land, we want to make sure that we make productive use of that land,” Davis says, whose team has developed solar farm vegetation programs for more than 3,500 acres of projects in 10 states. “We want solar farms treated like rich soil that we’re borrowing from our grandkids, who will be inheriting it after that solar asset hits its end of life in 30 or 40 years.” Continue reading here.

How to Combine Solar and Geothermal Energy Sources

By Holly Welles, Blue and Green Tomorrow

In terms of energy expenses, you can expect to save as much as 80% each year on hot water, heating and cooling when you switch from an HVAC system to a geothermal heat pump. Recent trends in these heat pumps — like smaller, modular “mini-split systems” — have made them an even more appealing option. As context, mini-split systems are a newer generation of geothermal heat pump which enables a homeowner to heat and cool a few rooms at a time, selectively. A zoned approach to heating and cooling and a solar energy system is often less expensive than central air conditioning and natural gas heat. Read more here.
