Battery dispatch authority is a core financing term for energy storage projects in Southeast Europe. It determines when systems charge and discharge, affecting revenue, degradation and compliance with market obligations. As storage fleets expand, the balance between short-term income and battery life can influence project cash flows and financing outcomes.
Storage projects may involve owners, lenders, EPC contractors, original equipment manufacturers, optimisers, aggregators and transmission system operators, with differing responsibilities and priorities. An owner may delegate daily dispatch to a trading house, while an optimiser may aim to maximise short-term gross revenue. Lenders and equipment manufacturers may instead prioritise preserving usable capacity and meeting warranty limits.
The issue concerns projects at different stages across the region. Bulgaria’s financed Tenevo project has a capacity of 246 MW and energy storage of 512.5 MWh. Romania had 55 storage units operating by 1 October, with total capacity of 1,162 MW.
Dispatch requirements and lender safeguards
Hungary’s 2026 rules require stationary storage above 2 kWh to be registered and remotely controlled. This places battery dispatch within regulated system operation rather than treating it only as a private trading decision. A bankable dispatch agreement should set clear limits on maximum daily or annual throughput, minimum state-of-charge reserves and balancing-service commitments. It should also specify warranty exclusions, how emergency instructions from the transmission system operator are handled, and how the optimiser can be overridden. Revenue-sharing arrangements should not reward cycling for short-term income when it accelerates 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 operates conservatively across several markets while the other is over-cycled for short-term arbitrage. Dispatch rights therefore act as a financial covenant expressed in operational terms, controlling both cash flow and degradation.
