What is EWEC's new energy storage facility?

The planned facility is expected to provide up to 800 megawatt-hours (MWh) of storage capacity. Called Bess 1, the project will closely follow the model of Ewec's independent power project (IPP) programme, in which developers enter into a long-term energy storage agreement (ESA) with Ewec as the sole procurer.

What is a Bess Power Purchase Agreement (PPA)?

The project will involve the development, financing, construction, operation, maintenance and ownership of the BESS system and associated infrastructure, with EWEC then entering into a long-term power purchase agreement (PPA) for the project's offtake.

What is a solar power plant in South Sudan?
