The World Bank approved a £275m ($380m) loan facility for the construction of the Upper Cisokan pumped storage hydroelectric power station in September 2021. The Asian Infrastructure Investment Bank (AIIB) is also expected to approve up to £180m ($250m) of loan for the UCPS project in the fourth quarter of 2021,. . PLN launched the Upper Cisokan pumped storage (UCPS) scheme in 2008 after receiving key environmental permits from the government in April 2007. The World Bank approved a £388m. . The Upper Cisokan pumped storage hydroelectric power projectis located in West Bandung and Cianjur regencies in West Java, Indonesia The. . The Upper Cisokan pumped storage hydroelectric power plant will comprise a 156.6m-long, 26m-wide, and 51.15m-high underground powerhouse equipped with four vertical-axis Francis reversible pump turbine units of 260MW. . The lower reservoir of the project will be created with the construction of a 98m-high roller-compacted concrete (RCC) gravity dam with a 294m. [pdf]
The Indonesian Ministry of Finance has awarded a US$380m loan to the power utility PT PLN for the construction of the 1,040 MW Upper Cisokan pumped-storage hydropower project, to be located between Jakarta and Bandung in Indonesia. In September 2021, the project received a US$380m loan from the World Bank.

JERA has been working to support Indonesia’s energy transition, carrying out studies and providing other support aimed at drawing up a decarbonization roadmap for the country’s power sector (25 November 2021 press release).
One of the companies from the United Arab Emirates, Masdar, collaborated with PT PLN Nusantara Power to build a Floating Solar Power Plant in the Cirata Reservoir, West Java. “But they want a large-scale bidding block, so that economies of scale are achieved in sufficient capacity.
PLN launched the Upper Cisokan pumped storage (UCPS) scheme in 2008 after receiving key environmental permits from the government in April 2007. The World Bank approved a £388m ($640m) loan for the project from the International Bank of Reconstruction and Development (IBRD) in May 2011.
Indonesia’s state-owned power company, Perusahaan Listrik Negara (PLN), is developing the project with an estimated investment of £560m ($775m). PLN awarded contracts for the civil works of the project in the second half of 2015, while the construction was started in the next year, but later delayed due to financial issues.

A battery energy storage system (BESS) or battery storage power station is a type of technology that uses a group of to store . Battery storage is the fastest responding on , and it is used to stabilise those grids, as battery storage can transition from standby to full power in under a second to deal with . BESS are the power plants in which batteries, individually or more often when aggregated, are used to store the electricity produced by the generating plants and make it available at times of need. The fundamental components of a Battery Energy Storage System are the blocks formed by the batteries, but other elements are also present. [pdf]

The Moss Landing Energy Storage Facility, the world’s largest lithium-ion battery energy storage system, has been expanded to 750 MW/3,000 MWh. [pdf]

Battery storage power plants and uninterruptible power supplies (UPS) are comparable in technology and function. However, battery storage power plants are larger. For safety and security, the actual batteries are housed in their own structures, like warehouses or containers.
The Moss Landing Energy Storage Facility, the world’s largest lithium-ion battery energy storage system, has been expanded to 750 MW/3,000 MWh. Moss Landing is in Monterey County, California, on the site of a gas-powered plant.
Meet the 1,200 MWh/300 MW Vistra's Moss Landing Energy Storage Facility, which easily beats the nearby Tesla installation (730 MWh/182.5 MW) and the previous largest Hornsdale Power Reserve in South Australia - 150 MW / 193.5 MWh after expansion.
The Gateway and Moss Landing projects are just two of the battery energy storage installations being developed across California, a state that has ramped up its use of renewable energy in recent years while phasing out electricity from coal, nuclear, and natural gas-fired power plants.
Gateway Energy Storage is currently energized at 230 MW and is on track to reach 250 MW this month, according to McCarthy. The project was launched and connected to CAISO’s grid in June, with an initial 62.5 MW of storage. LS Power said the project reached 200 MW of capacity on Aug. 1, with an additional 30 MW added on Aug. 17.
