What Encon Services International does

Encon Services International is a private energy consulting firm founded in 2003 in Bethesda, Maryland, with a European operational headquarters in Sofia, Bulgaria established in 2004. The firm provides consulting services across the full project lifecycle for energy efficiency and renewable energy initiatives, including energy audits, feasibility studies, pre-feasibility studies, project business plans, technical and financial due diligence, implementation monitoring, and verification of energy savings and emissions reductions for lenders and investors. Encon's portfolio spans industrial and commercial facilities, municipal and central government clients, and — distinctively — international financial institutions (EBRD, EIB, KfW, World Bank) and bilateral aid agencies (USAID), for which the firm designs and administers sustainable energy credit line facilities. Its proprietary BEERECL model, developed for the EBRD between 2004 and 2014 and replicated across multiple subsequent facilities, is a notable technical asset, alongside ISO 9001:2008 and ISO 50001 certifications and Bulgarian Energy Efficiency Agency licensing for energy audits.

The company operates a B2B and B2G professional services model, generating revenue through project-based consulting fees on quote-based engagements. Its go-to-market is sales-led and relationship-driven, relying on direct engagement with IFI program managers, prime contractors on donor-funded frameworks (notably Tetra Tech on USAID projects), municipal procurement processes, and enterprise clients. Over 20 years, Encon has completed more than 600 sustainable energy projects across 12 countries in Eastern Europe, Southeast Europe, and Central Asia, mobilizing over EUR 247 million in client project investments through the BEERECL program alone. The firm operates as a small specialist consultancy (11-50 staff) with a multilingual, multinational team and no external institutional ownership.

Encon's core technology is its codified methodology and project preparation expertise rather than a software or hardware platform. The company has expanded from traditional energy efficiency and renewable energy (biomass, biogas, wind, solar, small hydropower) into emerging areas including green hydrogen (2024 VEI Invest engagement for a 30 MW electrolysis plant) and water utility efficiency (2021-2022 EBRD engagement across seven Bulgarian regional water operators). It holds no patents or proprietary technology products, and there is no evidence of AI/ML capabilities embedded in its service delivery.

Scale indicators6 records

Recent moves6 records

Expansion highlights4 records

Emerging players

• Carbon Trust: UK-based non-profit consultancy advising companies and governments on energy efficiency, decarbonization, and climate finance. Comparable in offering (advisory, M&V, financing support) though geographically weighted toward Europe and the UK.
• EcoAct (Carbone 4 group): Carbon and energy consultancy within Carbone 4 group offering advisory, carbon finance, and project development support; competes in adjacent donor-funded energy advisory mandates in Europe and emerging markets.

Others

• Schneider Electric Energy & Sustainability Services: Global energy management and industrial automation major. Documented as the contracting prime for which Encon executed building energy audits in Sofia Business Park; broader energy advisory adjacent to Encon's auditing work.

Broad incumbents

• DAI Global: International development company implementing USAID energy and climate programs in Eastern Europe and Central Asia, prime contractor on many of the same types of projects Encon supports as a technical sub.
• Tetra Tech ES: Global engineering and development consulting firm that holds USAID Power the Future and MESA prime contracts and subcontracts Encon. Operates a far broader portfolio, but is the relevant comparison for IFI/donor-funded energy assignments.
• Mott MacDonald: Global engineering consultancy whose energy and climate teams deliver EBRD/EIB/World Bank energy efficiency and renewable energy advisory mandates across Eastern Europe and Central Asia, directly comparable IFI footprint.
• ICF International: US-based advisory and digital services firm with a large energy and climate practice that competes for similar energy efficiency, renewable, and policy advisory contracts with USAID, EPA, and utility clients.

Direct peers

• Allplan GmbH: Austrian engineering consultancy that co-delivered OeEB and NEFCO-funded energy efficiency programs in Southeast Europe and the Caucasus alongside Encon, with overlapping mandates in financial sector EE studies.
• Econoler: Canada-based energy efficiency and renewable energy consulting firm that has jointly delivered GIZ/KfW/USAID-funded programs. Documented as consortium partner with Encon on a Green for Growth Fund study in Moldova and Macedonia.

Regional players

• Glocal Foundation / Regional Environmental Center: Regional environmental and sustainability organization active in the same Eastern European and Central Asian markets, frequently partnering with the same IFIs and USAID on municipal/energy programs.
