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 Generating Station in Pueblo and invest $2.5 billion in renewable energy and battery storage. The utility expects the plan to save ratepayers $213 million. In January, the utility solicited notably low bid prices for wind-plus-storage, $21/MWh, as well as $36/MWh for solar-plus-storage, some of the lowest bids for renewable energy plus storage on record.

Colorado trades away coal and gas for solar+wind+storage, PV Magazine The Colorado PUC has voted to provide initial approval of a plan to retire 660 MW of coal early, and not build any new gas, instead constructing over 1 GW of wind, 700 MW of solar pv and
275 MW / 1.0 GWh of energy storage.
Falling Renewables Prices Present ‘Unprecedented Opportunity’ For Western Co-ops, North American Windpower. To illustrate the importance of this broad regional trend, RMI produced a case study of Tri-State Generation and Transmission Association, a nonprofit, member-owned cooperative utility that provides power to more than 1 million consumers in Colorado, Nebraska, New Mexico and Wyoming . . . According to RMI, the results of the study are consistent with the broader market trends illustrated though publicly available contract prices for new renewable resources in the Mountain West.
NRDC’s Pamela MacDougall and Vignesh Gowrishankar report on new energy storage research that indicates that using EVs for grid storage instead of stationary batteries could save electricity customers billions of dollars.
A study recently published by researchers at the Lawrence Berkeley National Laboratory (LBNL) shows that the electric vehicles (EVs) expected in California in 2025 could be used to meet the majority of the Golden State’s energy storage mandate that calls for 1.3 gigawatts (GW) of battery capacity by 2024. In fact, EVs can accomplish this both reliably and at about one-tenth the cost of stationary energy storage approaches. This level of storage could power nearly one million average homes, at least for a short while. That EVs can be this valuable to the grid is a hugely significant finding. Read morehere.

The South Sioux City Council has applied to the State of Nebraska for funding that would go toward a two-megawatt energy storage unit to ensure lower rates on the utility bills of residents. Here’s how it all works: Read more here.
1.5 cents per kilowatt-hour. That’s how much NextEra Chief Financial Officer (CFO) Jim Ketchum estimates that batteries have added to the cost of solar and wind projects that the company has built over the last six to 12 months, as revealed in the company’s second quarter results call yesterday. But that’s not all. Ketchum further added that he expects this cost to fall to around half a cent per kilowatt-hour in the middle of the next decade. Read more here.

NextEra is developing OPPD’s 5-megawatt solar project in the Fort Calhoun area. Would adding storage be an economical option in the near-term? Omaha World-Herald news stories about the solar project:
A new report from the Institute for Local Self-Reliance describes some of the implications of the growing solar power and energy storage trend as it relates to the current, centralized utility-based electricity distribution model. Because solar and energy storage can be cost competitive with grid electricity prices in some places, consumers now have an alternative to only using utility-based electricity. Report author John Farrell answered some questions for CleanTechnica.
When it comes to truly transformative energy technologies, energy storage should be on the short list. While it feels like there is never any good news these days, energy storage is shattering records, meeting milestones, and writing its own good-news story.
Because of its many benefits, states, utilities, and even big corporations are increasingly interested in investing in energy storage. Lawmakers are also interested in the opportunities energy storage presents. The U.S. House of Representatives Energy and Commerce committee has announced the latest installment in their “Powering America” hearing series: The Role of Energy Storage in the Nation’s Electricity System for Wednesday July 18. Members of Congress will examine the growth of large-scale energy storage in the United States, the unique reliability attributes energy storage provides for the electric grid, and the use and impacts of energy storage within wholesale electricity markets.

A much heralded report shows solar and wind will lower wholesale prices, but it also shows a coming evolution in the pricing profile of the grid. These shifts in timing, shape, regularity and length will drive energy storage demand. Read the entire articlehere.
Solar-Plus-Storage Microgrids Installed in Santa Rita Schools, Renewable Energy Magazine Solar PV plus Sharp SmartStorage® energy storage systems have been installed at six sites within the Santa Rita Union School District in Salinas, California. The systems will provide up to seven hours of power at each school during a grid outage and are expected to offset the school’s energy and demand usage resulting in savings on its utility bills.
Pennington, N.J., Dept. Of Public Works Adopts Solar-Plus-Storage, Solar Industry It is one of four similar projects that are in service as part of PSE&G’s Solar 4 All program, 158 MW DC solar initiative that uses rooftops, parking lots, utility poles and landfills/brownfields for large-scale, grid-connected solar projects.
