Which countries have a guidance document on Bess?

ADB, IRENA, and IFC have all issued guidance documents and handbooks on BESS, but the case material for economic and financial analysis is limited, again draws mostly in practice in the market-based systems of the developed countries or focuses on estimating the levelized cost of energy storage.

How can a first-mover country achieve 5 GW of Bess commitments?

Through the BESS Consortium, these first-mover countries are part of a collaborative effort to secure 5 gigawatts (GW) of BESS commitments by the end of 2024. In order to achieve the estimated 400 GW of renewable energy needed to alleviate energy poverty by 2030 and save a gigaton of CO2, 90 GW of storage capacity must be developed.

What is the Bess consortium?

The BESS Consortium is a multi-stakeholder partnership set up to ensure these BESS benefits transform energy systems across low- and middle-income countries (LMICs). The Consortium is on track to meet its target of securing 5 GW of BESS commitments by the end of 2024 and deploying these by the end of 2027.

How much power does a Bess need?

It follows that one would need a BESS with a power capacity of 120 kW with a duration of 3.17 hours (or 380 kWh of storage), to avoid the 500 kW threshold. Obviously in practice one would need to look at more than one day of load, and in more than one season, which will likely increase both the power and duration requirements.

How much would a Bess cost?

The analysis then asked at what investment cost would the BESS be economic, and determined that the breakeven point (NPV=0 at 10% discount rate) was 1,602 $/kW for 4 hours duration ($401 kWh), a price at which, in 2015, it noted would be expected to be achieved by 2020.

What are the benefits of a Bess project?

It should be emphasized that while a BESS project may be deployed with one of these primary applications in mind e.g. for peak load shifting or T&D deferral or integration with VRE, it is more usual that the BESS will provide multiple benefits.
