Romanian renewable developer Enexus plans to install 50 MWh of battery storage alongside two solar projects in Titu, Dâmbovița county, extending its cooperation with LONGi beyond photovoltaic modules.
The two hybrid sites will combine 55 MW of solar generation with battery storage. Enexus has already installed more than 200 MW of LONGi solar modules in projects developed since 2025.
LONGi will supply 10 utility-scale battery units using liquid cooling and integrated medium-voltage skids. The equipment is intended to simplify construction and reduce the additional infrastructure required at the project sites.
Liquid cooling should maintain more stable battery-cell temperatures, supporting operating performance and reducing thermal stress. The medium-voltage integration can also shorten installation and commissioning schedules.
The batteries will allow Enexus to move part of its solar production from lower-priced daytime periods into higher-value hours. They may also provide balancing, frequency and other grid-support services, depending on market access and final operating configuration.
Romania’s rapid expansion of solar generation is increasing the need for flexible assets. High photovoltaic output can depress midday electricity prices, while evening demand continues to require thermal generation or imports.
Hybrid projects can improve the commercial profile of solar assets by reducing curtailment exposure and creating additional revenue streams. Their economics will nevertheless depend on connection terms, balancing-market rules and the size of intraday price spreads.
The Titu projects mark Enexus’s first battery order with LONGi and reflect a broader shift in Romania from standalone renewable development towards integrated generation and storage.
