Lead acid battery storage project financing options in Czech 2026

Do hybrid batteries need long-term debt funding?

While long-term institutional debt funding of stand-alone and portfolio battery storage transactions has been relatively limited, there is a growing appetite for long-term nonrecourse debt funding of hybrids, which benefit from 20- or 30-year PPA offtake terms.

Are battery storage projects funded on a stand-alone basis?

KBRA has observed an important distinction in the funding tools for battery storage depending on whether batteries are being funded on a stand-alone basis or as part of a portfolio, versus those that are part of hybrid projects (utility-scale solar or wind combined with battery storage).

Do European and UK regulators support battery energy storage systems?

The success in recent capacity market auctions in Italy and the UK, as well as other European countries that are building large-scale battery energy storage systems (BESS) projects, signals that the European and UK regulatory environment is providing a degree of limited support to the technology.

How are battery storage transactions funded?

Funding techniques vary, but most battery storage transactions are funded on a short-term basis, taking into account corporate risk rather than on a pure stand-alone, nonrecourse basis. Regulation has a role in bridging the gap between inherent merchant exposure and long-term lenders’ needs for predictable cash flows.

How many MW of battery storage contracts were awarded in February?

The UK’s T-4 Capacity Market auction awarded 1,093MW of battery storage contracts in February. Around 60% of battery storage had a two-hour or longer duration, similar to the UK T-4 2024-25 results (storage duration is the amount of time storage can discharge at its power capacity before depleting its energy capacity).

Who is responsible for battery & portfolio storage revenue streams?

The principal counterparty in each case is typically the independent service operator (ISO), which is responsible for grid operation. A key characteristic of current stand-alone battery or portfolio storage revenue streams is that they are volatile and exposed to a high degree of price and supply/demand risk.
