Central Time at the date in the RFP Schedule above. There is no fee required to submit a NOIR. Upon receipt of a bidder’s NOIR, the Company will respond to the bidder with a link that will enable them to submit their bids electronically to a secure file sharing site and wiring instructions for submittal of bid fees. Respondents who fail to submit a NOIR will not be able to submit bids. The Company notes that bid and fee submittal are electronic only and physical copies or checks will not be accepted.

In the 2024 All-Source Solicitation, all proposals will be submitted electronically via a secure, confidential file upload application (XpressDRIVE).

Proposals received later than the submission deadline will be rejected and unopened, unless the Company determines, in coordination with the Independent Monitor, to consider such proposals. Any bidder submitting proposals after the submission deadline should immediately send an email to SPSRFP2024@XcelEnergy.com documenting why the proposal was submitted late.

Each individual bid package should be submitted as a single .zip file with completed bid forms in executable format.
