Cornerstone Laid for the Utilitas Paljassaare Heat Pump Plant

KMG Infra OÜ is pleased to participate in the construction of Utilitas’ Paljassaare heat pump plant. Last Tuesday, the official cornerstone was laid on-site – a significant milestone marking the progress of the project.

The 110 MW plant currently under construction will, in the future, cover a substantial share of the heat demand of Tallinn’s district heating network and will contribute to a notable reduction in CO₂ emissions. This environmentally sustainable and technologically innovative infrastructure project is an honour for KMG Infra to oversee as the main contractor.

KMG Infra extends its gratitude to all cooperation partners for their trust and excellent collaboration.

At the beginning of the month, the Rail Baltica Alliance Market Dialogue took place at the Öpiku Conference Centre in Tallinn in a B2B speed-meeting format.
The event provided more than 40 suppliers and companies with the opportunity to meet the Alliance members face-to-face.

During the meeting, participants were introduced to the upcoming scope of works and the planned start of construction activities. In addition to the general overview, “speed dating” sessions were held in technical workgroups — 15-minute focused discussions on specific topics, allowing for direct exchange of information and contacts.

Participants gave very positive feedback on the format, confirming strong cooperation and a shared commitment to the project’s success.
Similar information sessions are planned to continue in the near future to ensure that expertise and innovation are fully integrated during the development phase.

On May 22, 2025, AS Utilitas Tallinna Soojus and KMG Infra OÜ signed a contract for the design, general and specialized construction works, and project management of the Paljassaare wastewater and seawater heat pump plant and the seawater pumping station. This contract forms a part of AS Utilitas Tallinna Soojus’ major development project.

The execution deadline for this procurement contract is December 2026, and the contract value exceeds EUR 23.5 million (excluding VAT).
This is an extremely complex and high-responsibility project.

About Utilitas’ Major Development:

Utilitas is building the country’s first large-scale heat pump plant in Paljassaare, Tallinn, that will produce clean thermal energy from wastewater and seawater. The plant, with a total capacity of 110 MW, will start supplying heat to the district heating network in 2026.

The emission-free heat pump facility will utilize heat extracted from treated wastewater and seawater, upgrading it to district heating temperatures using green electricity. The integration of Tallinn Water’s Paljassaare wastewater treatment plant, seawater, heat pumps, and the district heating system represents an innovative and environmentally sustainable solution, being implemented in Estonia for the first time.

Under this contract, the following will be constructed:

Paljassaare põik 14 – Heat Pump Plant:

  • The heat pump plant will provide an energy-efficient and environmentally friendly district heating solution.
  • It will use natural sources (treated wastewater and seawater) for heat production.
  • The facility will consist of two tall machine halls, with a three-story section containing technical rooms between them.
  • The northwest part of the building will include a basement level (approx. 7 meters underground) housing a seawater reservoir and technical rooms.
  • The building will be constructed on pile foundations.

Paljassaare tee 1 – Seawater Pumping Station:

  • A seawater intake filtering system and pumping station.
  • The facility will use seawater as an energy input source, allowing for the stabilization of input flow rates and increasing heat output.
  • The building will consist of one underground level (approx. 9 meters deep) and one above-ground level (with parapet height approx. 9 meters above ground).
  • The structure will also be built on pile foundations.

Specialized construction works include:

  • Technological piping and equipment
  • HVAC
  • Electrical works
  • Low-voltage systems
  • Commissioning and testing of the station

The technological portion of the pump stations, including procurement and installation of pipes and equipment, will be carried out by KE Infra.

Last Friday, on May 16, 2025, a major step was taken toward the realization of Estonia’s largest infrastructure project to date: two alliance contracts were signed, one of which – covering the Pärnu–Ikla section – KMG Infra is honored to be a part of.

“This groundbreaking initiative supports connectivity and sustainable mobility across the region.”

In April 2023, we signed a contract for the railway facility for the Rail Baltica Ülemiste terminal constructions. The total duration of the work is almost 4 years, and the work is divided into two stages. We started the construction of stage I in October 2023 and handed it over to the customer in December 2024.

The construction of stage II is planned to start in the summer of 2025 and to be completed by the end of 2026.

The construction is in consortium with Merko Ehitus Eesti AS.

Phase I summary video

KMG Inseneriehituse AS board member, Mr Indrek Pappel, stated that building such a unique bridge presented a serious challenge and required very high level project management both in communications with partners from abroad as well as in solving cross border logistical issues, in order to complete the bridge in its current configuration. The technical solution employed allows the closing and opening of the bridge within a few minutes and by doing so provides the fastest route between A and D terminals of the Old Port of Tallinn.

The design and construction works took a total of 16 months. KMG Inseneriehituse AS wishes to thank all its cooperation partners for their efforts to make this unique structure a reality.

Biggest stormwater pumping station in Estonia was designed and built by KMG Inseneriehituse Ltd.

The pumping station is one of the most technologically sophisticated facilities that has been built in Estonia recent years. The pumping station was built on the sea border and has a depth of up to 12.9m below the ground (-10.5m below sea level). The bottom area of the pumping station is 750m2 and the volume is over 6300m3. It took more than 2,700m³ of concrete and more than 440 tonnes of reinforcing steel to build the pumping station.

6th of Aprill a new contract between KMG Inseneriehituse AS and AS Tallinna Sadam was signed for designing and building a new movable pedestrian bridge to Tallinn Old Harbour. New bridge will connect A- and D terminal for easier connection between them. Because the bridge connects to quay´s and the boat-traffic remains there, then the bridge will be built as first movable bridge in Estonia.

Contract includes all the design and construction works with 5 year warranty and maintenance period.
Project period is 16 months and the total cost is 4,22 mln EUR (VAT excluded).
