Sustainable Power Supply Alternatives for the Residence area of the ALMA Observatory/ FCFT-PR133689 -FLA

Request for information (RFI) to identify companies that are interested in and capable of developing and implementing a sustainable (including renewable) power generation system to supply the electricity demand of the Residence area of the ALMA Observatory, located 3,000 meters above sea level, and 18 kms south of San Pedro de Atacama, Chile. The objective of the RFI is to gather information from companies with proven technical and operational experience in sustainable energy solutions suitable for remote environments. Along the technical development of the solution, the participating companies shall identify the possible commercial and financial schemes for the project, indicating alternative contracting models , including the possibility of a mid-term agreement (for example Power Purchase Agreement PPA, or other), allowing ESO to evaluate the potential technical approach and commercial frameworks for the project. The RFI will be released in Q3/2026 to potential suppliers in the ESO Member States and in Chile. The scope of the potential contract includes the supply and on-site installation of the system. Both must be provided locally, i.e. either by the contractor if present locally, or through a recognized partner in Chile. Based on the outcome of the RFI, ESO will assess the technical and commercial viability of the project and, subject to this assessment, define the appropriate implementation strategy and required timeframe for the required solution. ESO will also define the list of eligible countries before releasing the Call for tender. ESO plans to issue the Call for tender during Q1/2027 and will inform the interested suppliers of their eligibility in advance.
