Bess in solar Tanzania

Is Bess a viable bridging technology for solar power off-grid sites?

The BESS technology, at current and forecasted costs are commercially viable for bridging the, more-or-less daily, variability and adverse weather events for solar energy to power off-grid sites at this scale. However, they are not yet cost effective at bridging the load supply for sustained periods (> 1 day) of limited solar resource availability.

Are solar PV and Bess a viable option?

Solar PV and BESS are increasingly becoming a viable option in the face of volatile fuel costs and declining renewable energy and battery costs. More details on cost reductions are presented in the appendix. The high upfront costs of BESS, and especially that of small-scale Li-ion batteries, influences the uptake of BESS in different industries.

What is a Bess model?

The model makes the conservative assumption that this energy is curtailed (similar to PV and wind energy exceeding demand/required dispatch), though in practice part of this energy can be charged to the BESS, or the BESS discharge for that hour can be reduced to use the excess thermal output.

How many kW is a Bess power plant?

BESS energy capacity kWh 6 72 160 BESS power capacity kW 2,5 20 35 Solar plant kWp 2,5 20 36 Wind farm kW - - - Thermal plant kW - 15 50 BAU thermal plant

When will Bess be deployed in South Africa?

The World Bank is also targeting the deployment of further BESS in South Africa, as well as in the West African Power Pool. These systems are likely to utilise Li-ion technology with deployment in the coming 5 to 10 years.

What are Bess operational technology parameters?

BESS Operational Technology Parameters: • Defines, for each energy storage system included in the model, the roundtrip efficiency, maximum and minimum state of charge (during operations), auxiliary load, self-discharge, and spatial requirements.
