TriGranit has signed a Power Purchase Agreement (PPA) with UNIMOT for the supply of electricity from renewable sources to the Signum Work Station office building in Warsaw for the next three years. Westbridge Advisory Poland advised on the negotiation of the agreement for the property located in the Mokotów district.
A PPA is a direct long-term contract between an energy producer and an end user that provides fixed pricing and traceability of the energy source. Such agreements are typically used to stabilise energy costs and reduce exposure to market price fluctuations.
Under the contract with UNIMOT, electricity supplied to Signum Work Station will come from wind and photovoltaic installations located in Poland. The total volume of electricity covered by the agreement is expected to exceed 12 GWh over three years. According to estimates provided by the parties, the new procurement model may generate savings of more than PLN 300,000 compared with previous arrangements due to more predictable pricing and lower exposure to CO₂-related charges.
The agreement is also expected to reduce CO₂ emissions by approximately 8,750 tonnes over the contract period, based on Poland’s emission factor.
Marta Zawadzka, Head of Leasing and Asset Management at TriGranit, said: “Entering into a PPA for Signum Work Station forms part of our long-term strategy to strengthen the building’s value and resilience – both operationally and as an investment asset. We focus on solutions that tangibly enhance cost stability, reduce exposure to energy market volatility, and at the same time support the energy transition. Direct access to renewable energy from traceable sources is now one of the key factors driving the competitiveness of modern office developments. For our tenants, this translates not only into predictable and lower energy costs, but also into measurable support for achieving their ESG objectives. The PPA provides assurance that they are using genuinely green energy, enhancing the credibility of reporting and stakeholder trust. It is a solution that increases the building’s attractiveness today while safeguarding its value over the long term.”
Preparation of the agreement and negotiations were coordinated by Westbridge Advisory Poland, which provides energy and sustainability advisory services to the real estate sector.
Tomasz Kwiatkowski, Senior Consultant at Westbridge Poland, commented: “By signing the PPA for Signum, TriGranit has secured the majority of the building’s electricity demand with green energy sourced from farms located in Poland. This demonstrates a highly conscious approach to the energy transition, where stability, cost security and a tangible reduction of the carbon footprint were of paramount importance. We are pleased to have advised on this pioneering transaction, which sets a new benchmark for the commercial real estate sector.”
Signum Work Station is located on Domaniewska Street in Warsaw’s Mokotów business district. The office building comprises seven above-ground and three underground floors and offers more than 32,400 sq m of leasable space, along with approximately 870 parking spaces. In addition to office areas, the property includes retail, service and storage units. The building holds a BREEAM “Excellent” certification and is undergoing further certification processes. Recent upgrades include the installation of two independent power sources intended to improve operational reliability.
The property is situated around 15 minutes by car from Warsaw city centre and approximately 10 minutes from Warsaw Chopin Airport, with access by public transport, car and bicycle. Current tenants include Ringier Axel Springer, enel-med, Mondelez International, Columbia and PPD.
Signum Work Station was acquired by DRFG in December 2024. The current owners are the CREIF fund and DRFG Investment Group, acting through DRFG Assets. TriGranit, part of DRFG Investment Group, is responsible for leasing and asset management of the building.
