Asset · Portfolio · Zonal

Solar forecasting at the level you make decisions.

Forecast a single plant, the portfolio you trade, or the market around you. The commercial object comes first; the modelling approach follows.

01 · Asset

Your plants

Forecast each solar plant on its own terms.

Use Asset Forecasting when the performance of the individual plant matters. Each site is modelled independently using its location, technical characteristics and operational conditions.

Best for: Asset managers, operators and trading teams managing plant-level positions.

Explore Asset Forecasting
02 · Portfolio

Your position

Forecast the position you actually trade.

Use Portfolio Forecasting when multiple solar assets are managed as one commercial position. The portfolio is modelled jointly to capture diversification, changing composition and shared market exposure.

Best for: Utilities, aggregators, IPPs and trading desks managing multiple assets.

03 · Zonal

Use Zonal Forecasting to estimate total solar production across a bidding zone or control area for trading, fundamental analysis and intraday market decisions.

Best for: Power traders, analysts and market participants looking beyond their own portfolio.
