Open-Source Software to Connect Different Energy Storage Systems and Increase Profits

energyPilotedTRL 7

Imagine trying to use a universal remote for every brand of TV and stereo in your house so you don't have to buy a new system every time you change brands. This project creates a similar 'universal translator' for energy batteries and storage tech. It lets different types of hardware talk to the same control system, making it easier to sell stored energy back to the grid.

The business problem

What needed solving

Energy storage hardware is fragmented, leading to vendor lock-in and high integration costs. This makes it difficult for operators to monetize their storage flexibility across different technologies.

The solution

What was built

An open-source middleware that virtualizes storage technology to make it hardware-independent. It includes testing software for interoperability certification.

Business applications

Who can put this to work

Energy Management
enterprise
Target: Virtual Power Plant (VPP) Operator

If you are a VPP operator dealing with fragmented hardware from different battery vendors — this project developed an open-source middleware that removes vendor lock-in. This allows you to integrate diverse storage assets into one platform to maximize flexibility sales.

Renewable Energy
mid-size
Target: Solar and Wind Farm Developer

If you are a farm developer dealing with the high cost of proprietary storage controllers — this project developed a technology-agnostic software layer. This enables you to switch storage hardware providers without replacing your entire management software.

Software Development
SME
Target: Smart Grid Software Vendor

If you are a software vendor dealing with the complexity of supporting 10 different storage protocols — this project developed a virtualized middleware. You can integrate this into your commercial platform to instantly support a wide range of storage technologies.

Frequently asked

Quick answers

What is the cost or pricing for this solution?

Based on available project data, the middleware will be released as a full open-source product, meaning the core software is available without a purchase price.

Has this been tested at an industrial scale?

Yes, the solution is being validated in 4 real-life living labs across Italy, Austria, Germany, and Portugal, as well as one laboratory in Spain.

What are the IP and licensing terms?

The project is developing an open-source product and intends to ensure software maintenance continues through the Linux Foundation Energy.

How does this integrate with existing systems?

The middleware is designed to be technology-agnostic and is being integrated into both open-source and commercial platforms, accounting for both new and legacy systems.

When will the results be available for business use?

The project period runs from 2023-01-01 to 2025-12-31, with the goal of ensuring adoption in commercial platforms by the end of the project.

Consortium

Who built it

The consortium is heavily industry-driven with a 62% industry ratio, comprising 8 industrial partners and 2 SMEs. This strong commercial presence, combined with 13 partners across 7 countries, suggests the project is focused on market adoption rather than pure academic research.
