Pourquoi VoltWatt

An EPC partner you can trust on site

What sets VoltWatt apart on European renewable construction sites — self-performance, safety culture and multi-technology capability under one roof.

Self-performing EPC at heart

We are not a project manager subcontracting the work — VoltWatt directly performs civil, electrical and commissioning scopes, eliminating margin stacking and interface risk between trades.

Zero-incident safety culture

Comprehensive HSE training, daily safety briefings and strict adherence to international safety standards — protecting people on every site, every day, on every project we build.

Solar, wind, storage — one EPC

Multi-technology construction capability under one roof: utility-scale PV, rooftop C&I, onshore wind and battery storage — diversified portfolios delivered by one accountable EPC team.

Who we build for

Built for every kind of asset owner

Each construction programme we run is tailored to the governance, reporting and accountability requirements of the asset owner — institutional, industrial, EPC partner or public authority.

Investisseurs, fonds & IPP

Turn-key, lender-grade renewable assets built to specification — bankable performance proven at commissioning, warranties enforced, full operations & maintenance handover documentation delivered.

  • Lender-grade construction reporting
  • On-schedule debt drawdowns
  • Clean asset & warranty handover

Industriels & acheteurs corporate

Turnkey rooftop, ground-mount and storage installations on industrial sites — VoltWatt designs, builds and commissions, with the asset delivered ready to power your operations under a long-term PPA.

  • Rooftop and ground-mount C&I solar
  • Behind-the-meter battery storage
  • CSRD-aligned construction reporting

EPC Partners & Subcontractors

Structured work-package programmes across our European pipeline — clear scopes, fair risk allocation, prompt payment and a repeat-business pipeline for partners who deliver to specification.

  • Pre-qualified subcontractor framework
  • Standardised work packages
  • Repeat European project pipeline

Autorités publiques & collectivités

Public-asset renewable construction — schools, hospitals, social housing, municipal land — executed to public-procurement standards with full local-content reporting and community consultation.

  • Public-procurement compliant delivery
  • Local employment & supply-chain reporting
  • Consultation et engagement communautaires
