Publication of two major new versions of the GAP and DAP in 2026: focusing on storage, geothermal energy, net metering and e-mobility

February 2026. The energy sector takes a new step forward in 2026 with the publication of two enhanced versions of the strategic tools GAP (Generation Analysis and Planning) and DAP (Demand Analysis and Planning). These updates mark a significant advance in energy planning, integrating technologies and uses that have become essential in modern electrical systems.

The new version of GAP 2026 introduces, for the first time, modules dedicated to energy storage and geothermal energy, two key levers for strengthening the flexibility, resilience, and sustainability of the energy mix. Storage now allows for more precise modeling of the supply-demand balance, particularly in the face of the increasing reliance on intermittent renewable energies. The integration of geothermal energy, meanwhile, paves the way for better utilization of this still under-exploited resource in the region, offering stable and low-carbon production.

For its part, the 2026 version of the DAP is enhanced with highly anticipated features, in line with current industry trends: net metering, which facilitates the integration of decentralized producers, and e-mobility, now essential in energy transition strategies. These additions allow for a more precise assessment of the impact of residential photovoltaic installations, charging stations, and new consumption patterns on distribution networks.

With these developments, the GAP and the DAP reinforce their central role in modern energy planning. They offer decision-makers, operators, and regulators more comprehensive, more flexible tools, better suited to the technological and environmental challenges of the decade. These 2026 versions are thus fully aligned with the dynamic transformation of electricity systems, where flexibility, decentralization, and electrification are becoming the key principles.
