Battery Energy Storage
BESS is the missing link of the energy transition — essential to integrate variable renewables, monetise ancillary services, and avoid curtailment. Grid-scale storage is the fastest-growing infrastructure asset class of the decade.
Why storage matters now
Duck-curve dynamics, coal retirement, and EV adoption have made dispatchable capacity a system-critical service. Falling Li-ion prices and improving cycle life have collapsed BESS LCOS below diesel and OCGT peakers.
Revenue structuring
Standalone contracted (tolling), merchant (energy arbitrage plus ancillary), solar-plus-storage hybrid, and virtual capacity products. QSL structures the right mix to be bankable in each jurisdiction.
Where we work
REIPPPP BESS bid windows in South Africa, ERCOT and CAISO merchant markets in the United States, Chile's stability of supply auctions, and Colombia's emerging reliability charge.
