C3S2_412_bis Lot 2 Enhanced C3S Energy Service

ECMWF, as the Entrusted Entity for the Copernicus Climate Change Service (C3S), invites Tenders to enhance the C3S Energy Service. The requirements are split into two Lots: co-development of online seasonal demonstrators and tools with champion energy users (Lot 1), and maintenance of operational services for the energy sector (Lot 2).

For each Lot, ECMWF intends to award a single Framework Agreement for a period of maximum 33 months, which shall be implemented via a single multi-annual Service Contract expected to commence in April 2026. Tenderers are invited to submit their Tenders for either one or both Lots. Note that the expertise required for each Lot strongly differ. In cases where a Tenderer opts to submit Tenders for the two Lots, it is mandatory that each Tender is presented as a separate submission, with its own set of documents, including but not limited to, technical proposals, pricing tables and any required supporting documents. Tenderers must ensure that the submissions for each Lot are independently viable and stand on their own merits.

Lot 2: Maintenance of Operational Services for the Energy Sector

Lot 2 aims to maintain and further develop selected climate and energy products, as well as related C3S reports. Two ongoing contracts are currently delivering datasets, Jupyter Notebooks, software, and web applications to the CDS and C3S users. This new activity is intended to ensure the continued maintenance and, where necessary, the updating of those outputs.
