$VirtuPlan™. Energy Tuned. VirtuPlan™ turns distributed energy assets into dispatchable capacity for virtual power plants. 8 million assets are already connected worldwide, and the grid will need 3× more flexibility by 2030. Generation capacity is not the constraint. Coordination is. VirtuPlan™ sits between physical assets and operational control, combining AI with deep grid engineering, and scales to thousands of assets. Plug it into an existing VPP control stack or deploy it as a turnkey solution. Normal asset operation stays untouched. Unlock energy markets and ancillary services: frequency response, congestion management, standby capacity. Every dispatch decision respects regulatory, operational and technical constraints, optimized across all of them at once. VirtuPlan™ is part of HMAX™ Energy. Built on a proven foundation, then customized to your systems behavior and your defined objectives. Faster than building new grid infrastructure, at a fraction of the cost.
