DeltaE Inseneribüroo

What DeltaE Inseneribüroo does

DeltaE Inseneribüroo (legal entity: DeltaE Insenerid OÜ) is a Tallinn-based engineering firm founded in 2013 (originally as Hoiame Kokku Grupp, rebranded in 2018) that delivers end-to-end energy and resource efficiency solutions to Estonian industrial and commercial clients. Its service portfolio covers energy and resource audits, reactive-energy compensation and electrical-quality analysis, building automation, HVAC design and inspection, measurement systems, compressed-air audits and ultrasonic leak mapping, professional lighting design and automation, and solar station design, construction and maintenance. Technical work is supported by a proprietary Dynamic Energy Monitoring System for ongoing consumption tracking. The firm's clients are predominantly Estonian manufacturing enterprises — wood, metal, food, electronics, cement, steel, recycling and printing — and commercial real estate operators, with named engagements spanning from small audits (€10K–20K) to multi-hundred-thousand-euro solar and resource-efficiency capex projects. Operational track record cited by the company includes ~3,000 energy-saving projects, 1,100+ industrial sites, 600+ commercial real estate assets, 1.5+ MW of solar capacity built generating ~1.5 GWh/year, and >€22M in grant applications filed with a 100% success rate.

Revenue is generated through project-based professional services (audits, design, installation) priced on custom quotes, hardware pass-through as exclusive Estonian importer of SITECO luminaires and SDT ultrasonic devices, and recurring managed services for monitoring and maintenance. The go-to-market is enterprise field sales with expert-led free consultations, supported by content marketing, training sessions for sustainability representatives (~500 trained annually), and an ecosystem referral network via The Green Tiger, EVEA, LHV Bank and Swedbank. Distribution is domestic Estonia plus selective regional expansion into neighbouring countries via existing client footprints. DeltaE operates without disclosed external funding, M&A activity, or parent-company ownership, and is led by board member and energy expert Marti Arak alongside construction manager Kristjan Kookmaa and HR manager Pille Juhkov.

• Ramboll: Denmark-headquartered global engineering consultancy with a large Energy practice spanning energy efficiency, district energy, and renewables. Overlaps with DeltaE on energy audits and efficiency engineering but serves a much broader portfolio of services and geographies.
• AFRY: Swedish engineering and design consultancy formed from the merger of ÅF and Pöyry, with substantial energy, infrastructure, and industrial engineering capabilities. Competes with DeltaE for industrial efficiency mandates in the Nordics and Baltics at a much larger scale.
• Stantec: Global engineering, architecture, and environmental consulting firm with energy and sustainability practices. Comparable to DeltaE in delivering energy assessments and resource-efficiency advisory for industrial and real-estate clients, though at vastly greater scale and geographic reach.
• WSP: Global engineering professional services firm with a dedicated Energy and Property & Buildings segment delivering energy audits, MEP design, and decarbonization advisory — competing for the same large-enterprise efficiency mandates that drive DeltaE's audit pipeline.
• Schneider Electric: Global energy management and industrial automation company whose EcoStruxure platform and energy-advisory services target the same building-automation, monitoring, and efficiency outcomes that DeltaE delivers through its Dynamic Energy Monitoring System and BMS offering.

Others

• Elering: Estonian transmission system operator responsible for the high-voltage grid. Not a direct competitor, but a closely adjacent infrastructure player whose grid-investment and balancing-market decisions shape the demand environment for DeltaE's electrical-quality and reactive-energy services.

Regional players

• Eesti Energia: Estonian state-owned integrated energy company offering energy production, sales, and increasingly energy-efficiency and solar services to Estonian industrial customers — the dominant domestic counterparty whose own efficiency initiatives overlap with DeltaE's addressable market.
