A testimonial from Groupe E, one of Switzerland’s largest grid operators

In this webinar replay, Ana Nazaré, Strategic Asset Manager at Groupe E, shared how Groupe E uses Cosmo Tech AI-Simulation software to optimize its long-term grid investment strategy. She explained how, by accounting for uncertainties from asset aging to smart grid flexibility scenarios, the AI-Simulation software helps the company identify the renewal plan and assess the reinforcement projects showing the best trade-off. This approach balances CAPEX, asset value, service quality, and energy transmission costs — validating up to –30% CAPEX optimization in the process.

Maxime Le Pendeven, Key Account Director at Cosmo Tech, presented how simulation supports stakeholder alignment for strategic investment planning, while also enabling short-term prioritization of projects — as Groupe E also shared its first learnings on its extended use of Cosmo Tech for Investment Portfolio Management in 2025.

This 45-minutes session was moderated by Stephanie Kidder, Chief Marketing Officer at Cosmo Tech.

Key takeaways from the session:

• Explore all possible strategies, anticipate risks and outcomes over time
• Assess smart grid flexibility with full KPI visibility 
• Optimize trade-offs and synergies between renewal and reinforcement plans
• Strengthen investment portfolio prioritization and execution under constraints

This case study is part of a five-year collaboration between Groupe E and Cosmo Tech. From strategic investment planning to portfolio-level decision-making, Groupe E uses AI Simulation to manage the cost and risks of grid transformation.
