The Jwaneng Solar Power Station is a 100 MW (130,000 hp) , under development in . Two companies and one Botswana (IPP) formed a that owns the project. (BPC), the national electricity utility company is the power off-taker, under a 25-year . The World Bank Group has approved plans to develop Botswana’s first utility-scale battery energy storage system (BESS) with 50MW output and 200MWh storage capacity. The World Bank will support the 4-hour duration BESS via a loan of US$88 million. [pdf]
In July 2021, the Botswana Energy Regulatory Authority (BERA) also approved the project, and issued a generation license. The power station is under development by a consortium comprising Shumba Energy Limited from Botswana and Solarcentury Africa, based in the United Kingdom.
Botswana is home to several power stations, including Morupule Power Stations B (600 MW) and A (132 MW), Orapa Power Station (90 MW), and Phakalane Power Station (1.3 MW).
In a few years Botswana could be generating enough power internally to supply all of its domestic needs General electrification is the main objective of the Government. The feed-in tariffs (FITs) are yet to be developed by the government. The National Development Plan (NDP) 11 places an emphasis on self-sufficiency.
In November 2018, BPC issued a Request for proposals relating to the development, financing, construction, operation and maintenance of 12 solar PV power projects. In a few years Botswana could be generating enough power internally to supply all of its domestic needs General electrification is the main objective of the Government.

The energy storage owners transfer the use right to users for additional income, which avoids the waste of energy storage resources; the energy storage operators reasonably allocate energy storage resources according to the demand of users, and earn service fees via professional management and control of energy storage resources; users utilize the energy storage resources by signing contracts with operators to save the cost of self-built energy storage devices.

Community shared energy storage (CSES) is a solution to alleviate the uncertainty of renewable resources by aggregating excess energy during appropriate periods and discharging it when renewable generation is low. CSES involves multiple consumers or producers sharing an energy storage system.
In fact, shared energy storage systems can be an effective way to increase the efficiency and reliability of the energy system, regardless of whether consumers have their own PV systems or not. Comparing Figs. 4 and 5 demonstrates that CSES decreases the injecting power of consumers into the local grid.
In this model, the operator of the shared storage system sets the energy prices based on the expected demand and supply conditions in the market. The community members then use this pricing information to determine the time of consumption and the amount of energy [ 19, 20 ].
Simulation results show that the flexibility of shared energy storage could improve the performance of virtual power plants in joint markets. The optimal bidding strategy for energy storage operators depends on the strategy of other community members.
To use the shared energy storage system, community members can lease the capacity of the CSES. In other words, the maximum purchased power from or sold power to the shared storage is limited by the leased capacity. The leased capacity represents the share of the CSES' capacity that each consumer can use.
The model found that one company’s products were more economic than the other’s in 86 percent of the sites because of the product’s ability to charge and discharge more quickly, with an average increased profitability of almost $25 per kilowatt-hour of energy storage installed per year.
