What Colenco does

COLENCO is a Germany-based (COLENCO GmbH, Lauchringen) consulting and engineering firm with its primary operating entity in Skopje, North Macedonia (COLENCO Ltd.), and additional wholly-owned subsidiaries in Bulgaria, Albania, and Kosovo. Founded in 2012 as AF-Consult Ltd. Skopje under ÅF Group before being rebranded to COLENCO, the firm provides full-lifecycle engineering and consulting services across energy, infrastructure, and industrial development. Its service catalogue is organized into four business units: Transmission & Distribution (including Power System Analysis), Heat & Power (thermal, hydro, energy efficiency, district heating), Renewable Energy/Policy & Regulations (PV, BESS, wind, floating PV, decarbonization, climate, policy), and Infrastructure & Industrial Development, supported by phase-gated project services spanning feasibility, design, procurement and tendering, construction supervision, FIDIC Engineer, Lender's Engineer, Owner's Engineer, and defect notification period support.

Technical execution relies on industry-standard power-system and renewable-engineering software—PSS/E, NEPLAN, DIgSILENT, ANTARES, PLEXOS for grid masterplans and market coupling studies; PVSyst, WAsP, and MARKAL/TIMES for solar, wind, and energy-economic modeling. The firm holds the full ISO management suite (9001, 14001, 45001, 27001, 50001) and design-supervision-construction licenses in North Macedonia, qualifying it for IFI-financed tenders.

Revenue is generated through professional-services engagements priced on a quote basis against scope, typically multi-year, and predominantly financed by EBRD, KfW, the World Bank, and EIB. The go-to-market is enterprise field sales targeting governments, ministries, regulators, transmission system operators (TSOs), utilities, and private renewable developers in Southeast Europe, with stated expansion into Sub-Saharan Africa, MENA, Eastern Europe/CIS, and Asia. Scale signals include 124 completed projects, 85 clients, presence in 52 countries, and a documented consulting footprint across 2,000MW+ of renewable installed capacity in the SEE region. Strategic distribution runs through direct enterprise engagements, IFI procurement channels, and joint venture/consortium partnerships with firms such as ILF, EKONERG, VITA Institute, Dornier Suntrace, and UTA.
