Description
Rectification T146764: TenneT has identified an error in the “Schedule of Prices and Rates - HKZ Alpha and Beta Jacket Inspection Services”. Line items 5a, 5b and 6 of the schedule are referring to day rates for variations only. These should be included in a separate line of prices exclusively for variation day rates and not in the main tender schedule of price. As a result of this error, TenneT could not evaluate the received tenders. Please be advised that TenneT will disregard “Schedule of Prices and Rates HKZ Alpha and Beta Jacket Inspection Services” submitted in relation to the tenders received on 6th June 2025. TenneT confirms that this information will not be used and be kept confidential to guarantee fair competition. To rectify the error, TenneT has amended the “Schedule of Prices and Rates - HKZ Alpha and Beta Jacket Inspection Services” dated 18th of April 2025 accordingly and published the revised version on Mercell. TenneT hereby grants all tenderers the opportunity to resubmit the “Schedule of Prices and Rates - HKZ Alpha and Beta Jacket Inspection Services” with the revised version Rev. 2 dated 24th of June 2025”. On the “Schedule of prices and rates” all items, including the variation, should be priced.
