SIG pumps cold water from Lake Geneva through a planned ~30 km hydrothermal network to heat and cool buildings across the city
clm-8394fad0985ebec8
quantitative
It grew from GLN (Genève-Lac-Nations), a 5 km network with a lakeside pumping station born in 2008; UN Geneva was its first customer, connecting in 2009, with the WHO, ITU, WTO and WMO following

descriptive
GeniLac now runs as two loops — an open one into the city centre as far as the Rhône, and a closed one reaching the airport and the Quartier de l'Etang — with further loops planned for the PAV district, the Gare des Eaux-Vives and the university hospitals

quantitative
SIG says the installation runs on 100% renewable electricity and cuts the electricity a connected building uses for cooling by 80%, and its heating CO2 by 80%
clm-2137f63874c6db2f
quantitative
SIG reports that GeniLac produced 33 GWh of cooling and heat in 2021, nearly 30% more than in 2020, with 68 customers connected
clm-e6f2db2fd0955e12
quantitative
by 2045, once 350 buildings are connected, SIG expects 70 GWh of electricity saved a year — the annual consumption of 27,000 households — and 70,000 tonnes of greenhouse gases avoided a year for the Canton of Geneva

quantitative
A visiting reporter was told in 2022 that the network would be finished by 2024
This layer records what is known about each source, what is still missing, and the exact snapshot this page is rendering. A missing date, archive or hash stays visible as missing.
Awaiting operator and domain-expert review; publication of this revision implies neither.

src-378b9aa9d8a652a0SIG's own account of the GeniLac deployment. Source for the two loops and their reach, the 80% reductions, the 2045 projection, the delivered 2021 output (33 GWh of cooling and heat, nearly 30% up on 2020) and the 68 customers then connected, and for the prehistory: 'GLN, Genève-Lac-Nations, est né en 2008, composé d'une station de pompage au bord du lac et d'un réseau de 5 km', with UN Geneva connecting first in 2009 and the WHO, ITU, WTO and WMO following. The page carries no date of its own; its content describes 2022. The page states no publication date.
src-0f174226b3545185Published 7 November 2019. Gives the cost with a dollar equivalent — 'A CHF800 million ($805 million) new pumping station is under construction north of Geneva as part of the Genilac project' — attaching the figure to the pumping station rather than the whole network. Its separate 80% cooling figure refers to a hotel in Lucerne, not to GeniLac.
src-f5ce48a071f0be05Published 5 August 2022, from a Heidi.news site visit. Source for the 30 km extent, the Vengeron pumping station, pipes submerged at 45 metres drawing water at about 7 degrees, the 68 customers, and two figures worth keeping apart from SIG's: 'The project is expected to be completed by 2024 for a total outlay of around CHF 800 million.'
