Dispatch authority is a core financing term for battery storage projects in Southeast Europe because it determines when systems charge and discharge, affecting revenue capture, degradation and compliance with market obligations. As storage fleets scale, the allocation of control can shape cash flows and the operating limits that lenders and equipment providers seek to protect.
Large battery projects can involve owners, lenders, engineering, procurement and construction contractors, original equipment manufacturers, optimisers, aggregators and transmission system operators. Their responsibilities and priorities may differ. An owner may delegate daily dispatch to a trading house, while an optimiser may seek to maximise short-term gross revenue. Lenders and original equipment manufacturers may instead prioritise preserving usable capacity and meeting warranty limits. That tension between near-term revenue and battery life becomes material as fleets grow.
Examples across the region include Bulgaria’s Tenevo project, a financed battery storage project with 246 MW of capacity and 512.5 MWh of energy storage. In Romania, 55 storage units were operating by 1 October, with total capacity of 1,162 MW. Hungary’s rules in force in 2026 require stationary storage above 2 kWh to be registered and remotely controlled. Those requirements treat battery dispatch as part of regulated system operation, not solely a private trading decision.
A bankable dispatch agreement should set explicit maximum daily or annual throughput and minimum state-of-charge reserves. It should also define balancing-service commitments, warranty exclusions, how emergency transmission system operator instructions are handled, and the process for overriding the optimiser. Revenue sharing should avoid rewarding an optimiser for cycling that produces near-term income while accelerating long-term degradation.
Lenders should assess the battery controller as carefully as the hardware when underwriting a project. Two otherwise identical batteries can produce different debt outcomes if one is optimised conservatively across several markets while the other is over-cycled for short-term arbitrage. Dispatch rights therefore function as a financial covenant expressed in operational terms: they control cash flow and degradation, as well as how a battery meets its market obligations.
