Answers to your questions

How to describe Re-Twin Energy in one sentence?

Re-Twin is your AI-powered digital energy analyst for evaluating, simulating, and optimizing risk vs. return for battery assets.

What is Re-Twin Energy's platform?

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.

What makes Re-Twin Energy a one-stop-shop?

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?

What is a digital twin?

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.

Who can benefit from the Re-Twin Energy platform?

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.

What energy storage systems are included?

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.

What does the Investment Analysis module do?

It assesses project viability and profitability using historical and forecast data, helping users explore different asset configurations and market strategies before making investment decisions.

What is Live Benchmarking?

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.

What type of data does Re-Twin Energy deliver?

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.

In which format is the data downloadable?

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.

For which countries is the platform available?
