Answers to your questions
Re-Twin is your AI-powered digital energy analyst for evaluating, simulating, and optimizing risk vs. return for battery assets.
Re-Twin is a one-stop SaaS platform with three tools: Data & Insights, Investment Analysis, and Live Benchmarking. Built to make battery storage decisions faster, smarter, and more profitable.
We support the full asset lifecycle from planning to operation with scenario analysis, trading simulations, and performance benchmarking. Re-Twin answers key questions like:
- Which markets should my battery target?
- How do I balance returns and asset health?
- What profit can I expect from different strategies?
A digital twin is a 1:1 virtual copy of your battery asset (real or planned). It mirrors all changes of your set-up, helping you optimize performance and strategy without risk.
Stakeholders in energy storage (developers, asset owners, and financiers), especially in the battery storage space, use Re-Twin for project planning, strategy testing, and operational performance benchmarking.
We focus on battery energy storage systems (BESS), including stand-alone assets and co-located setups like BESS+PV, BESS+Wind, and BESS+Own Consumption.
It assesses project viability and profitability using historical and forecast data, helping users explore different asset configurations and market strategies before making investment decisions.
Live Benchmarking is a new performance measuring concept, that shines where generic indices fail to capture your assets unique set-up. It’s a live trading simulator where users test and improve strategies in a risk-free environment to balance returns, risks, and asset degradation. Results act as benchmarks for your trader or asset against real outcomes. This can further be applied to validate assumptions and provide third-party verification.
Re-Twin provides historical market data and long-term forecast market data (based on FFE & MAON), trading simulations, market-specific revenue projections, cashflows and scenario results tailored to your asset. This data also incorporates degradation, based on your inputs. Project specific parameters can be set to tailor the output.
The Re-Twin Optimizer itself is trained on various data sources incl. price data for spot & ancillary markets from different countries, weather and much more. This means we are also able to generate a PV Generation Profile based on your chosen location.
Data and results can be exported in CSV, Excel, or PDF formats (based on your use case and plan). Downloads are in 1 hour granularity, PRO users get the additional option to download in 15 min granularity.
The platform currently supports Germany, Belgium, Austria, Netherlands and Spain with expansion to other European markets underway. Interested in bringing Re-Twin to your country? Get in touch! We are always looking for pilot partner’s to expand to new countries.
