iON+ and ACCURE partner to simplify BESS data access for owners and operators

iON+ will provide data services and support to ACCURE customers, via a comprehensive data bridge which supports extraction and recording of high-frequency data points from the BESS system. This will help unlock new insights for owners.

iON+ can be used to facilitate the transfer of comprehensive data from BESS assets to the ACCURE platform in near real time. The data bridge can also return corrected values such as State of Energy (SoE), which owners can use in dispatch and trading decisions. iON+ data services is just one part of the modular asset performance management and dispatch solutions it offers to BESS and other renewable assets owners.

The partnership will save end-customers valuable time on data integration, with iON+ bringing high-frequency data from across their entire portfolio into ACCURE’s analytics. Correcting SoE using ACCURE’s analysis releases tradable MWh that would otherwise go unsold, and prevents the mis-delivery penalties that follow when available energy is overstated.

The value of correcting SoE is already proven in live operation with ACCURE’s client Gore Street Capital. At their 75 MW Dogfish site, a 1-hour BESS active in Texas, operating data projected an annual benefit above US$110 000, roughly a 5% uplift against average BESS trading revenues in ERCOT. Corrected values went live at the site in July 2026, delivered with no new hardware.

Capacity that sits offline earns nothing. ACCURE's platform gives owners and operators a continuous, independent view of every asset down to cell level, and its performance engineers work alongside their teams to act on what it finds. Issues such as imbalance are caught and fixed early, before they spread and pull capacity out of the market. That combination keeps capacity available, lowers maintenance costs and extends asset life, so batteries earn the revenue they were built for. Leading insurers, including Aviva and HDI, also recognise ACCURE’s continuous monitoring as part of their underwriting.

Rhys Kirk, Chief Technology Officer at iON+, said: “We are delighted to have formalised this mutually beneficial partnership with ACCURE. We have been working with ACCURE for some time and know from first-hand experience the breadth and quality of their analytics. We expect the partnership to help ensure that we and ACCURE continue to provide the highest quality of service to our customers.”

Yannick Gindroz, Head of Partnerships at ACCURE, added: “The iON+ team’s experience in extracting and transferring high-granularity data made them an obvious partner for us. In our industry, visibility is everything, and so we are always looking for ways to show our customers more of what their assets are doing. Working in partnership with iON+, who can provide our customers with a straightforward and efficient way to access their data, does exactly that.”
