Details

Expected Outcome:

Project results are expected to contribute to all the following expected outcomes:

  • Improved energy security of the energy system by offering cost-effective and efficient solutions for additional diverse and flexible energy storage capacities.
  • Improve the sustainability and circularity of energy storage systems.
  • Enhanced economic viability of energy storage by utilizing existing infrastructures.

Scope:

Demonstration of novel or improved technological solutions for cost-efficient, circular and sustainable energy storage, which contribute to grid flexibility and make use of existing obsolete or outdated energy or other infrastructures. Proposals should integrate the synergies between novel or improved energy storage technologies and retrofitting of obsolete or outdated infrastructures, like e.g. old hydropower dams and basins, decommissioned power plants, former industrial facilities, coal mines, fossil fuel infrastructure etc. by optimizing at the same time storage capacity and efficiency as well as circularity and socioeconomic and environmental sustainability, which should be addressed, e.g. by stakeholder outreach and consideration of possible environmental impacts. Furthermore, proposals should follow secure by design approach and integrate built-in security in the energy systems. Selected projects are expected to contribute to the BRIDGE initiative [1] and actively participate in its activities. null Activities are expected to achieve TRL 6-8 by the end of the project – see General Annex B. Activities may start at any TRL.

Context for bidders

We hold 219 notices from European Commission, going back to August 2026 — 219 of them still open. They buy mostly in Water & Environment, Healthcare & Pharma and IT & Telecom. There are 11 open space-satellite tenders in Global / multi-country. This one closes in 431 days.

Before you bid on this tender

A quick checklist to help you decide whether to bid and prepare a compliant submission for this space-satellite opportunity. Always verify the details on the official source.

  • Confirm the exact closing date and time (and time zone) on the official portal — deadlines are strict and can be revised by a corrigendum.
  • Read the full notice and every attached document, including the scope, specifications and any bill of quantities or terms of reference.
  • Check the eligibility criteria — prior similar experience, annual turnover, certifications and registrations — and make sure you qualify before investing effort.
  • Prepare any earnest-money deposit (EMD) or bid security and the required formats early; missing or wrongly-formatted documents are a common cause of rejection.
  • Note how bids must be submitted (online or physical), in what format, and whether a digital signature or portal registration is required.
  • Watch for corrigenda and clarifications right up to the deadline — requirements and dates can change.
