Energy performance & decarbonisation
The integrated partner for your energy transformation.
SEM OPM ENERGIE supports public and private organisations across the full energy lifecycle: audit, strategy, procurement, engineering, project delivery, compliance, monitoring and long-term performance optimisation.
Who we are
Advisory, engineering and project delivery within a single model.
SEM OPM ENERGIE structures and steers ambitious energy trajectories for complex assets — from the initial diagnostic through to operational performance, with no handover gaps between the disciplines mobilised.
Our integrated approach brings together strategic advisory, technical engineering and project coordination, securing every trade-off and every execution decision in service of our partners' long-term objectives.
Audit
Assess asset performance and identify energy efficiency opportunities across the portfolio.
Strategy
Build decarbonisation trajectories aligned with your commitments, constraints and investment horizon.
Delivery
Steer projects from design through commissioning, with rigorous control of cost and schedule.
Performance
Measure, optimise and sustain energy performance throughout the operational lifecycle.
Service ecosystem
An integrated capability chain for your energy transformation.
Eight coordinated expertise areas, orchestrated through a single strategic lead — from initial audit to continuous optimisation.
Energy audit & diagnostics
Establish an objective baseline of asset performance and structure a credible improvement roadmap.
Energy strategy & decarbonisation
Frame a long-term low-carbon trajectory aligned with regulation, financing and operational reality.
Renewable energy solutions
Structure the integration of solar, geothermal and biomass at site, multi-site or portfolio scale.
Project management & works coordination
Coordinate all stakeholders under a single lead — securing timelines, quality and energy performance commitments.
Compliance & certifications
