Co-located BESS Optimisation – Facts and White Paper

Prepared by Quantum Optima

Executive Summary

PV+BESS co-location reduces curtailment losses and enables solar plants to participate in energy markets more profitably.

Why It Matters

Curtailment of PV generation leads to direct financial loss.

A co-located BESS absorbs excess PV, discharges at higher-value hours.

Optimisation ensures maximum revenue and reduced grid stress.

Mathematical Formulation

Decision variables: P^pv_t, P^curt_t, P^ch_t, P^dis_t, SoC_t.

Constraints: PV balance, SoC dynamics, curtailment limits, grid balance.

Objective: Maximise Σ_t [ P^grid_t·price_t + λ_curt·P^curt_t − degradation cost ].

Case Study

A 50 MW PV plant in Greece facing 10% curtailment could regain revenues by installing and optimising a 20 MWh BESS.

Quantum Optima Positioning

Quantum Optima uniquely integrates quantum optimisation methods to co-optimise curtailment management and market arbitrage.
