ROUNDUP: Habitat Energy in Texas, FlexGen EMS updates, Nuvve’s new subscription service

Energy-Storage.news reported on Eni’s announcement of completing construction of the project. At that time, and at the time of reporting on the sale of the BESS from BayWa r.e. to Eni New Energy US, the BESS capacity was noted as 200MW/400MWh.

ESN asked Habitat Energy for clarification; the company noted that the system is 200MW/200MWh.

The BESS is located in Webb County, Texas, alongside Eni Plenitude’s Corazon solar farm, and is expected operational mid-2025.

Habitat will work to maximise revenue across wholesale and ancillary service markets using what it describes as:

“A combination of advanced algorithmic price forecasting and dispatch optimisation, expert human trading team oversight and extensive real-world experience of managing the physical performance and reliability of the asset.”

Headquartered in the UK, Habitat Energy is part of Quinbrook Infrastructure Partners. Habitat Co-founder and director Ben Irons talked to Energy-Storage.news about the challenges facing optimisation firms like it in a 2023 interview (Premium access article).

In the interview, Irons spoke about being transparent and, more importantly, generating revenue for project owners.

Habitat claims to provide optimisation services for over 1.2GW of battery storage and renewable energy assets in the Electric Reliability Council of Texas (ERCOT) region.

Recently, the company signed an agreement with Octopus Energy US to optimise its 50MW/100MWh BESS, also located in ERCOT.

Habitat also emphasises that it is not a software-only solution, but involves what it calls ‘Human-in-the-loop’ trading and operations for real-time monitoring, position and asset management.

Also from the Southern US, North Carolina-headquartered System integrator FlexGen Power Systems has announced its new battery health feature as part of its HybridOS energy management system (EMS).

FlexGen says the State of Health (SOH) feature will give customers a more reliable view of battery degradation to allow for long-term site planning through battery management system-reported SOH and proprietary FlexGen-calculated SOH.

SOH compares a battery’s current capacity to its originally expected capacity to measure the remaining capacity. This helps to identify when the cell has diminished and needs to be replaced.

Vendor-reported battery health is often based on test conditions while FlexGen says its EMS uses on-site conditions to better reflect the degradation of the battery.

The company claims that its new feature is continuously evaluating the amount f energy fow during charge and discharge events to estimate the rate of degradation, it then computes a degradation curve that is site-specific.

In 2024, FlexGen signed a joint development agreement (JDA) with Eos Energy Enterprises to create fully integrated BESS using Eos’ zinc-based batteries and FlexGen’s EMS.

Earlier this year, FlexGen secured a revolving credit facility (RCF) with J.P. Morgan for US$75 million.

While speaking with ESN, about the RCF, FlexGen CEO Kelcy Pegler said that the company will “lean into research and development,” focusing on emerging hardware and use cases for its technology.

US vehicle-to-grid (V2G) technology company Nuvve has announced the launch of its ‘Battery-as-a-Service’ (BaaS) programme.

While Nuvve is a sort of pioneer in the V2G space, it has a fairly low profitability, as revealed in its Q4 and full year 2024 financial results, where the company’s total revenue was “US$1.79 million for the three months ended 31 December, 2024.”

The BaaS solution may help the company to increase profits. It is a subscription-based service designed for electric cooperatives and other load-serving entities.

Utilities can deploy scalable BESS, also at the substation level, without a significant upfront cost. It is delivered through 10 to 12-year service agreements.

Nuvve explains that the BaaS platform is built to be scalable and application-flexible, with capital expenditure ranging from US$1 million to US$10 million.

The company provides procurement, installation, operation, maintenance and grid integration services.

Nuvve says deployments are expected to begin in late 2025.

In 2024, Nuvve entered a strategic partnership with Chinese battery and energy storage solutions manufacturer Guangzhou Great Power, which saw Nuvve pairing its energy management and aggregation platforms for electric vehicles with Guangzhou battery products.

Earlier this year, utility ComEd began a vehicle-to-grid (V2G) pilot programme in northern Illinois with Nuvve and integrated energy solutions company Resource Innovations.
