What we do

Five disciplines.
One delivery model.

Engineering, procurement, construction, storage, and the agrivoltaic work that comes with it. Each one self-performed, we do not subcontract the load-bearing engineering or commissioning.

01 / Capabilities

End-to-end, load-bearing engineering kept in-house.

01

Engineering & feasibility studies

Bankable site selection, yield modelling, grid-integration studies, IFC/EBRD-grade ESIA, delivered by an in-house team of 64 engineers across electrical, civil, geotechnical, and environmental disciplines. We don't outsource the work the lenders are going to read.

02

Procurement & supply-chain control

Tier-1 OEM relationships negotiated from inside the supply chain, our Qingdao HQ removes the middlemen. Multi-currency hedging, bonded warehousing in three regional hubs (Qingdao, Marseille, Basra). We don't lose six months at a port-of-entry permit because we have already cleared the next 60 containers.

03

Construction & site commissioning

Self-perform civils and electrical for sites above 50 MW. Locally trained crews everywhere we build, over 2,400 local engineers and technicians trained to date. Commissioning under IEC 62446, every string tested before energization, every test result in the lender's report.

Battery energy storage integration (BESS)

AC- and DC-coupled BESS up to 400 MWh, designed for arbitrage, capacity firming, and ancillary services. We dispatch our own SCADA stack and provide a 10-year performance warranty on round-trip efficiency, not just on availability, which is what most counterparties offer.

05

Agrivoltaic systems & land-use integration

Elevated arrays designed in consultation with regional agronomists, preserve cropland yield while generating power above it. Eight years of operating data across three climatic zones, including our Iraq greenhouse pilot. Co-revenue models for landowners as standard.

02 / Methodology

Four phases. Each one ends in a signed transfer.

The delivery model is deliberately linear. Each phase is contractually independent, investors can engage at any stage and exit at any phase boundary.

PHASE 013–9 months

Feasibility & bankability

Site selection, ESIA, yield modelling, grid-integration study, financial modelling. Output: bankable due-diligence package.

  • Geotech + topographic surveys
  • P50/P90 yield
  • IFC ESIA
  • Financial model · IRR / DSCR
PHASE 029–18 months

EPC delivery

Detailed engineering, procurement, construction. Single-counterparty EPC contract, fixed price, date-certain, performance-guaranteed.

  • Detail design freeze
  • Procurement & logistics
  • Civil works
  • Electrical install
PHASE 032–4 months

Testing & commissioning

String-level testing, energization, grid synchronization, performance-ratio acceptance. PR-guarantee threshold met before sign-off.

  • IEC 62446 acceptance
  • Hot commissioning
  • 30-day PR test
  • Lender's engineer sign-off
PHASE 04Ongoing · O&M optional

Operator handover

Asset transfer to the owner-operator. Optional 5–10 year O&M contract with availability and PR guarantees attached.

  • Final as-builts
  • O&M handbook
  • Local crew handover
  • Performance bond

“The Wattrex EPC contract reads like a project-finance lawyer wrote it, because they made sure one did. We have not needed a parent-company guarantee on a Wattrex job since 2021.
