This document discusses how the datacenter company Yandex recovered waste heat from its operations in Mäntsälä, Finland to provide district heating. The first phase of the project recovered 3.6 MW of heat, replacing 50% of the annual natural gas consumption and reducing CO2 emissions by 40%. This helped make district heating more competitive and the system will be almost CO2 emission free once the second phase is complete. The project was awarded the Finnish Climate Action of the Year in 2016 for this innovative cooperation between Yandex and the district heating company Nivos.

Technical Data (1st phase)
• Heat production 3,6 MW
• Replaces 50% of the annual natural gas consumption
• Reduces CO2-emissions 40% on annual level
• Equivalent to heating of 1000 single family houses
• Investment app. 2,5 M€ + the connection line to city centre app. 1M€
• Nominal Power input 1,2 MW
• COP: Between 4 and 2,7 depending on the drive
situation e.g. ambient temperature

13. 13 @NivosOy13
Significant positive impact
• We buy heat from Yandex based on normal commercial terms
• Reduced carbondioxide emissions
• First phase -40% less CO2-emissions,
this corresponds to the objective EU set for emission reductions in 2030
• Second phase -90 %,
district heating will be almost CO2-emission free in Mäntsälä
• District heating is more competitive
• In the future only peak heat load is covered with natural/bio gas
or wood pellets
• Yandex 2nd phaze is more optimized also from the heat
recovery perspective, leading to even better heat recovery and
higher output temperature
