Texas is leading the nation—and the world—in wind energy. After setting wind power generation records in October, Texas is swiftly getting to work on a massive $6.8 billion transmission project that will more than double its total installed wind power by 2013. Who knew the oil-centric state would become such a leader in renewable energy?

As of now, about 8 percent, or 10,000 MW, of Texas' power comes from wind, expected to jump up to 16 percent in the next year. While some Texas landowners are not happy about the lines set to cross their property, they will receive a onetime payment for hosting them. Texans will pay an approximate $5 more on monthly electricity bills to finance the project for years to come.

In the long run, wind is making electricity cheaper. Texas experienced intervals where wholesale electricity dropped to $0.00 in October due to wind power, siting more gains for the project. Part of the drop was caused by high winds at night, followed by a low energy demand on an early morning, but mostly, wind is just cheap—the cheapest form of renewable energy.

Another reason for the sudden demand to ramp up wind power generation is the growing concern of rolling blackouts caused by extreme weather, like the drought Texas experienced this summer, and its effect on power plants. Since power plants use water for cooling, the lower the water levels get, the bigger and more unpredictable the problem could be.

That's one of the advantages of wind farms—they don't use water. However, wind is not a total solution. It can be extremely variable from the coast to turbine farms in western Texas. The more the state increases wind capacity, the harder it will be for the Electric Liability Council of Texas (ERCOT), the state's electric grid operator, to maintain stability of the grid. There will also have to be a backup that can be readily available when wind is down.

What about solar? Donna Nelson, chair of the Public Utility Commission, notes in an interview with the Texas Tribune that solar energy is even more variable than wind. Although it hasn't been a viable option yet, according to Donna, recent dropping prices of solar panels may open up another avenue for renewables for the sunny state.

Despite the variability of wind power, Nelson sees an overall positive outcome of the large-scale project. “You're basically changing the way electricity has historically been measured, and you're changing the customers' interaction with it... So we're ahead of everybody else—Texas is,” Nelson told the Texas Tribune.

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.
