AS Connecto Infra

What AS Connecto Infra does

AS Connecto Infra is a privately-held Estonian infrastructure engineering and construction group that designs, builds, and maintains electrical power networks, telecommunications networks, gas networks, and related infrastructure across the Baltic states and Finland. The company operates through five wholly-owned entities — AS Connecto Eesti and AS Connecto Infra (Estonia, with the split effective 2025), SIA Connecto Latvija, UAB Connecto Lietuva, and CONNECTO-OHLAS OY (Finland) — and employs over 600 technical specialists including high-voltage, medium/low-voltage, telecom, renewable energy, and geodesy/design engineers. Its service portfolio spans seven interconnected lines: 35–330 kV high-voltage networks, 0.4–35 kV low/medium-voltage networks, telecommunications/fiber networks, gas high-pressure pipelines, geodesy and engineering design, an accredited High Voltage Laboratory (EVS-EN ISO/IEC 17025:2017 and EVS-EN ISO/IEC 17020:2012), and renewable energy / green energy EPC for wind, solar, and hybrid parks. Notable technical capabilities include submarine HV cable installation (Väike väin 6.9 km / 110 kV; Suur väin 9.7 km) and turnkey delivery of 330 kV substations and overhead lines.

Connecto generates revenue primarily through large-scale project-based construction services for national grid operators (notably Elering AS in Estonia and Litgrid AB in Lithuania) and renewable energy developers (Enefit Green, Ignitis Renewable, Sunly, Metsagrupp), with contract values ranging from approximately €7M to €34M per project awarded via competitive public procurement tenders. A second revenue stream consists of recurring maintenance and managed-services contracts covering Elering's western-Estonia HV grid (2021–2025), Telia Eesti's external telecom network (2001–2022), ELA SA's 6,000+ km of fiber optic infrastructure, and Estonian Railway cable networks — providing a more predictable recurring base on top of the lumpy project revenue. Group turnover exceeds €200M annually. Customer segments are B2B only — transmission and distribution system operators, renewable energy developers, telecom operators, gas network operators, municipalities, and railway operators — with no consumer-facing pricing or channels. The go-to-market is enterprise field sales driven by public procurement tenders and direct negotiated EPC contracts.

The company's 2025 strategic posture is defined by an accelerating pivot toward renewable energy EPC (Vārme 94 MW solar in Latvia completed May 2025; Sopi-Tootsi 255 MW wind + 74 MW solar for Enefit Green; Raba 45 MW solar for Sunly/Metsagrupp), the operational split of Estonian activities into two legal entities for clearer focus, and continued multi-country execution on high-voltage transmission tenders including the Lihula 330 kV substation (first 330 kV substation in western Estonia) and the 63 km LN531-LN447 330 kV line for Litgrid in Lithuania. Competitive advantages rest on regulatory accreditation, deep multi-discipline technical talent, embedded long-tenure maintenance contracts that create switching costs, and the scale to self-execute and bond nine-figure utility tenders.
