Siemens to build giant battery storage
Germany Energy storage Siemens Smart Infrastructure and Zukunftsenergie Nordostbayern GmbH have signed a letter of intent for the turnkey construction of a 100 MW battery storage facility in the German town of Wunsiedel. The plant, with a storage capacity of 200 MWh, is intended to use surplus renewable energy and cover demand peaks in the power grid.
The 5000 square metre facility will be based on a lithium-ion battery storage system provided by Fluence, a joint venture between Siemens and AES, and will be able
to store and release large amounts of green power, including during periods of otherwise expensive peak load matching.
Siemens will handle project management, including a technical implementation concept, as well as the construction of a medium-voltage switchgear system and connection to the high-voltage grid. Among other things, the letter of intent also includes the development of a financing concept. “This [facility] also benefits upstream grid operators because it gives them more flexibility to compensate for voltage fluctuations, which are increasingly common
because of the expansion of renewable energy generation,” said Bernd Koch, head of Technology Performance Services at Siemens Smart Infrastructure Germany. For the network operator, the solution promises significant relief. “Switching on and off large industrial plants in the grid area requires a lot of electricity,” said Siemens’ project manager Andreas Schmuderer. “Up to now, the network operator has had to maintain considerable reserves. If these can be eliminated in the future, there will be great potential for reducing CO2
emissions in the local energy market.”
Plans for a zero carbon power plant
UK Emissions abatement HyNet North West and independent power producer InterGen have announced plans to collaborate to create a low carbon power station at InterGen’s Rocksavage power plant in Liverpool, UK. Expected to begin in the mid-2020s, the partnership could
reduce the carbon dioxide emissions from the power station by over 150 000 tonnes each year. HyNet North West intends to begin its part of decarbonising the North West UK and North Wales regions from as soon as 2025, replacing fossil fuels currently used for electricity generation, industry, heating homes and transportation with hydrogen. The project will also include CCS facilities. InterGen anticipates that by 2028, Rocksavage will have enough hydrogen produced by HyNet to move towards a 100% net zero power generation power station as the gas turbine technology becomes available. The project will also play a big part in supporting
Liverpool City Region in its commitment to reach zero carbon by 2040.
World bank to support Uzbekistan’s transition Uzbekistan T&D
A $380 million project to upgrade Uzbekistan’s grid (run by National Electric Grids of Uzbekistan) has been approved by the World Bank.
The Electricity Sector Transformation And Resilient Transmission Project is to ensure a reliable energy supply across Uzbekistan. It is supported by $380 million in credit from the International Development Association (part of the World Bank Group), and a $43 million loan from the Green Climate Fund (GCF) under the Sustainable Renewables Risk Mitigation Initiative Facility.
The government of Uzbekistan will receive this financing at very low interest rates and a
long repayment period, of up to 40 years. The GCF will also provide a $4 million grant to cover selected project activities.
The project aims to support Uzbekistan in its clean energy transition by improving the transmission network’s capacity to integrate renewable energy produced by the private sector, to contribute to Uzbekistan’s plans to decarbonise its electricity sector, directly support the integration of 1500 MW of renewable energy into the power grid, and mobilise private investment into the country’s renewable energy sector.
The country’s electricity demand is expected to grow to over 100 TWh by 2030, a significant increase from 61 TWh in 2018. It has over

250 000 km of electricity transmission and distribution lines, most of which were built during the Soviet era and are now past their useful economic life.
This project with the World Bank is one of several major projects being undertaken in Uzbekistan, to improve digital and telecoms technologies to improve monitoring, control, and operation of the power transmission system, and to support NEGU’s transformation by introducing new business processes covering financial, operational, and commercial performance, digitisation, operations and planning functions, corporate governance, cyber security, and the transition to a competitive electricity market.
