Dispatch authority is a core financing term for battery projects in Southeast Europe because it determines when systems charge and discharge, affecting revenue, degradation and compliance with market obligations. The party controlling dispatch can therefore influence both project cash flow and the battery’s usable capacity.
Large storage projects bring together owners, lenders, engineering, procurement and construction (EPC) contractors, original equipment manufacturers, optimisers, aggregators and transmission system operators. Their priorities can differ: an owner may delegate daily dispatch to a trading house, while an optimiser seeks to maximise short-term gross revenue. Lenders and manufacturers may prioritise preserving usable capacity and meeting warranty limits. As fleets scale, the tension between near-term revenue and battery life becomes material.
The issue spans projects at different stages across the region. Bulgaria’s Tenevo project is financed, with a capacity of 246 MW and energy storage of 512.5 MWh. 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 dispatch as part of regulated system operation, not solely as a private trading decision.
A bankable dispatch agreement should specify maximum daily or annual throughput, minimum state-of-charge reserves and balancing-service commitments. It should also define warranty exclusions, how emergency transmission system operator instructions are handled, and how the optimiser can be overridden. Revenue sharing should not reward cycling for near-term income when that cycling 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 is operated conservatively across several markets and the other is over-cycled for short-term arbitrage. Dispatch rights function as a financial covenant expressed in operational terms: they control cash flow and degradation, making dispatch authority a core finance term.
