Asset-Specific Renewable Forecasts That Strengthen Operations and Trading Performance.

Portfolio Power Forecasts give energy companies a sharper, site-specific view of how their wind, solar, and hydro assets will perform, enabling more accurate planning, tighter risk control, and better commercial results. Instead of relying on generic model output, you get forecasts calibrated to your actual assets, continuously refined with live operational data.

Energy One provides 24/7 or Out-of-Hours gas and power operations and dispatching services.

Our team of 40+ experienced gas and power operators works out of three control rooms based in Paris (France), Aalst (Belgium) and Adelaide (Australia) using a follow-the-sun approach. This means that we ensure you always have operators working in daytime hours to manage nominations, bidding, scheduling and portfolio balancing on your behalf. Several of our experts have moved from our European offices to Australia, where they are taking care of the European night shift, ensuring you always have a fresh pair of eyes watching over your portfolio.
