Sunservice Ltd, a Bulgarian developer of large-scale solar power plants, is commissioning its first photovoltaic power plant, which will include SolarMax inverters, produced by Sputnik Engineering. The plant will be located in the town of Ihtiman, in western Bulgaria. The system generates a total output of two megawatts. The company, based in Sofia, has an additional six central SolarMax 330C-SV inverters installed. The devices have a rated output of 330 kilowatts each, achieving a maximum efficiency of 98 percent.

The company was dedicated to selecting the right inverter supplier for the plant. Rumen Christov, CEO of Sunservice, stated, "Sputnik has a lot of experience with central inverters." Christov expects the solar plant to generate 1,250 kilowatt hours, per kilowatt, annually. Based on the present Bulgarian infeed rate for power, the plant operator will be paid 37.2 euro cents for every kilowatt hour produced.

Because of the good irradiation conditions and the attractive price, Christov expects rapid growth in the Bulgarian solar market. "At present, in Bulgaria, less than 10 megawatts of photovoltaic capacity is installed,” said Christov. "This year, new plants with an overall capacity of 10 to 50 megawatts will be built. By 2015, in Bulgaria, plants will be producing a total output of 500 to 1,000 megawatts of solar power. By 2020 this figure will rise to 2.5 to 4 gigawatts.”“

Sputnik Head of Sales and Marketing, Daniel Freudiger, stated, “Bulgaria is a very important growth market for us. We have already signed several excellent partnerships and will continuously expand our network.” This past March, for example, in eastern Bulgaria the Swiss inverter manufacturer commissioned the country's largest solar plant with an overall capacity of 2.4 megawatts fitted with SolarMax central inverters.

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.
