Colorado approves Xcel plan to retire coal, shift to renewables and storage

By Catherine Morehouse, Utility Dive

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.

Study: Using EVs Instead of Stationary Batteries Could Save Billions

Guest Post, Microgrid Knowledge

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.

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 more here.

NextEra expects storage to add half a cent to solar in mid-2020’s

By Christian Roselund, PV Magazine USA

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.

New ILSR Report & Q&A With John Farrell: A Solar Power & Energy Storage Revolution Is Upon Us

By Jake Richardson, CleanTechnica

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.

Energy Storage: A Critical Player in a Cleaner Grid

Expert Blog by Elizabeth Noll and Arjun Krishnaswami
Natural Resources Defense Council

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.
