StellarBlue and Meteogen have entered a strategic partnership to deliver renewable production forecasting directly inside the ATLAS ETRM platform. Meteogen's PV and wind forecasts are now available as a native data source in ATLAS, giving asset owners, aggregators, and traders a single environment for forecasting, bidding, and portfolio operations.

The two companies have already worked together through shared clients, where Meteogen forecasts were integrated into ATLAS on a project basis. This partnership formalises that cooperation and makes the capability available to ATLAS customers through a specific integration license billed through StellarBlue.

About Meteogen

Meteogen is a Greek company specializing in production forecasting for wind and photovoltaic renewable energy assets. By combining numerical weather prediction, from global sources and models it operates in-house, with machine learning trained on asset-level operational data, Meteogen delivers accurate forecasts to producers, aggregators, and market participants across European energy markets.

About StellarBlue

StellarBlue is a specialised provider of advanced Energy Trading and Risk Management (ETRM) systems and fundamental optimisation modelling. Born out of deep academic and industrial expertise, we design the core technical architecture and strategic bidding algorithms made available by the ATLAS ETRM platform, enabling energy companies to navigate complex wholesale market structures with precision.

How the Integration Works

The integration runs as a closed loop between the two platforms. ATLAS retrieves forecasts from Meteogen through scheduled API calls configured per park, so every asset is mapped individually and each forecast lands against the correct portfolio position. In the other direction, ATLAS pushes SCADA measurements back to Meteogen in real time. That feedback allows the models to recalibrate against live plant behaviour and sustain refresh rates of up to 24 updates per day.

Where You Find It in ATLAS

Data Room and Math Editor

Every Meteogen forecast is maintained as a time series per park, alongside market prices, volumes, forward curves, and asset measurements, with the latest run always current. Each series is directly addressable in the Math Editor, so teams can build derived signals, blend providers, apply availability or curtailment adjustments, and construct custom accuracy metrics without writing code.

Back Office

The asset view brings Meteogen forecasts together with competing forecast providers, raw SCADA, and certified metered data on a single screen. Analysts can assess forecast quality per asset over any period and see exactly where deviations originate.

Scheduling

Forecasts feed directly into bidding and balancing workflows. Selected series drive day-ahead and intraday offer construction and imbalance position management, moving through the same approval workflows, volume controls, and fat-finger protections as any other input.

Dispatching

Intraday forecast refreshes drive optimal dispatch across the portfolio in real time. As updated forecasts arrive, ATLAS combines them with live SCADA measurements to recalculate asset schedules and correct imbalance as it develops, surfacing the adjusted dispatch directly to operators.

What the Two Teams Say

Forecast quality sits at the foundation of every bidding decision our customers make. Partnering with Meteogen lets us put proven renewable forecasting directly into the workflows our users already run in ATLAS, rather than asking them to stitch together another data feed. It is a natural extension of the platform and a strong fit between two Greek engineering teams.

— StellarBlue Founding Team
Great forecasts only create value when they reach the people making decisions with them. Integrating with ATLAS means our models plug directly into the workflow traders and analysts already trust, instead of sitting in a separate tool. We built Meteogen on the belief that forecasting should be judged by how it performs inside real market decisions. This partnership is exactly that test, at scale.

Looking Ahead

Renewable production forecasting is the first stage of the partnership. Both teams are exploring further forecasting capabilities to be delivered through ATLAS as customer requirements develop.

Partnership focus: Combining Meteogen's renewable forecasting expertise with the ATLAS ETRM platform to give energy companies accurate, high-frequency production forecasts inside the system they already use to trade.

Access and Licensing

Meteogen forecasting is available through a dedicated integration license billed through StellarBlue. Contact us to discuss the licensing and integration process and gain access to the complete solution: the Meteogen dashboard and API together with the Meteogen integration within ATLAS.

Our team coordinates activation and setup, giving you a clear path to bring renewable forecasts into your scheduling, bidding, and portfolio operations.
