- Authorization to perform specific activities or tasks: 9.1.1.

The Bidder shall confirm this participation condition by submitting a statement in Chapter IA of the ToR "Offer Form."

The Contracting Authority will verify fulfillment on a "meets/does not meet" basis based on the submitted statement in Chapter IA of the ToR "Offer Form."

If submitting an Offer as a Consortium, this condition must be met by each Consortium member.
- Knowledge and experience: 9.2.1. Authorized to use and offer substantive and technical solutions applied to the Contract subject, which will not infringe third-party rights.
The Bidder confirms this condition by submitting a statement included in Chapter IA of the ToR "Offer Form."
The Contracting Authority will verify fulfillment on a "meets/does not meet" basis based on the submitted statement in Chapter IA of the ToR "Offer Form."
For Consortium Offers, this condition must be met by each member.

9.2.2. The Bidder possesses the necessary knowledge and experience to perform the Contract, in particular, within the last 36 months before the Offer submission deadline, or if the business period is shorter – during that period, the Bidder has completed for independent external clients:

9.2.2.1. Delivery and participation in commissioning at least 6 energy storage units, each with a capacity of at least 10 MW, executed using LFP technology, with one-, two-, or four-hour systems, or delivery and participation in commissioning at least 1 energy storage unit with a capacity of at least 25 MW, executed using LFP technology, with one-, two-, or four-hour systems.

These deliveries must have been carried out on the territory of the Republic of Poland or other countries where regulatory, technical, and market conditions for delivery and commissioning of energy storage systems are identical or similar to those in Poland. This requirement does not limit experience solely to Poland but allows experience gained in markets with comparable technical standards, safety requirements, and legal frameworks in power engineering and energy storage.

This requirement for demonstrated knowledge and experience in deliveries and commissioning on specified markets, as well as the reference period, ensures the Bidder has experience in market, technological, and regulatory conditions comparable to those where the Contract will be executed. The indicated markets have similar technical standards, infrastructure development, safety requirements, and legal frameworks related to energy storage, allowing fair assessment of the Bidder's ability to properly execute the Contract. The reference period guarantees that the experience is current and reflects the latest technological solutions and industry standards. This limitation is not discriminatory and does not unjustifiably restrict competition but results from an objective need to ensure quality and safety of Contract execution.

The Bidder confirms this participation condition by completing and submitting Annex T03 "List of completed orders confirming knowledge and experience," including the declaration of proper delivery and commissioning.

The Contracting Authority will verify fulfillment on a "meets/does not meet" basis based on the submitted Annex T03.
