For years now we’ve seen the banter go back and forth between policymakers, businessmen, and the media in regard to the economic viability of wind power as a utilities-scale energy provider.  Technological advances and government subsidies will surely bring down the bottom line in wind power development, but let’s not forget how significant a role business partnerships can play in achieving the same goal.  Xcel Energy and NextEra Energy Resources have signed a contract to develop a new low-cost 200 MW wind farm in Colorado.

According to Xcel, the arrangement will allow for some of the cheapest wind power in the company’s portfolio. "Our contract with NextEra Energy Resources is one of the lowest we've ever seen and results in a savings of nearly 40 percent for our customers," says David Eves, president and CEO of Public Service Co. of Colorado, an Xcel Energy company.

He adds, "The addition of this 200-megawatt wind farm demonstrates that renewable energy can compete on an economic basis with more traditional forms of generation fuel, like natural gas, and allows us to meet the state's Renewable Energy Standard at a very reasonable cost to our customers."

The project was originally bid in January 2009, but 2010 saw an opportunity to rebid at a significant cost-reduction, which will offer a dramatic savings to customers.

The dramatic reduction in cost is the result of a slowing period in wind farm development resulting in a surplus of turbines in the American market.  The Colorado Public Utilities Commission’s confirmation of the market status ultimately led to the successful contract between Xcel and NextEra. 

The wind farm itself, dubbed the Limon Wind Energy Center, will consist of 125 turbines sitting atop 35,000 acres.  Construction will begin in early 2012 and completed later that year.  The addition of Limon will give Xcel Energy 1,943 MW of total installed capacity of wind power in Colorado.

Sungrow links Europe's largest energy storage plant to grid

Europe's largest energy storage project, the 100MWh Minety plant with Sungrow's 1500V energy storage system solutions, has connected to the UK grid

Europe's largest energy storage project, the 100MW/100MWh Minety plant featuring Sungrow's 1500V energy storage system solutions, has been successfully connected to the UK grid.

The UK experienced the most debilitating blackout in nearly a decade in August 2019. The incident exposed the serious lack of frequency regulation of the national grid and demonstrated that the construction of energy storage projects that can regulate the frequency of the grid in a timely fashion should be prioritised. The Minety project, which began at the end of 2019, considerably mitigates the problem and is designed for facilitating grid stability and maximising renewable energy utilisation.

Sungrow supplied both NCM and LFP battery energy storage system solutions featuring high integration, which minimise the footprint, slash the commissioning duration and significantly reduce the system cost by 5%. The solution well meets the latest UK frequency regulation requirement called dynamic containment - requesting the plant to respond to the power instruction of the grid within 1 second, making the project one of the rare 30% of the UK's storage plants equipped with this function.

"We are proud of being part of this landmark project, offering solutions with extreme efficiency and safety while in compliance with the stringent UK grid codes," said James Wu, Vice President of Sungrow, which shipped more than 800MWh of energy storage systems in 2020.

Battery storage capacity in the UK is likely to heavily increase as move towards operating a zero-carbon energy system. At the end of 2019 the GB battery storage capacity was 0.88GWh. National Grid forecasts it could be as high as 2.30GWh in 2025.

Global energy storage updates

TEVOCS has announced the launch of a powerful series of universal portable power stations that provide reliable power for off-grid situations, travel, home backup and more. With an impressive 2080WH capacity and 2000W output, the TEVOCS power station is billed as 'the ultimate power station for modern life' and is available here.

Enlight Renewable Energy has completed the acquisition of 90.1% of the holdings in Clēnera LLC, a leading and seasoned company in the field of initiation, development, construction and operation of solar energy and energy storage projects in the United States.

Last month Canadian Solar Inc. was awarded the first utility-scale battery storage project in Colombia of 45 MW/45 MWh. The project was awarded in the public tender launched by Colombia's Ministry of Energy and Mines, via its affiliate UPME, the Mining and Energy Planning Unit.
