Archived-W&S-46: The Letter of Credit amount provided in the draft part 2 Proposal requirements is $15,000/MW. Is it correct that this is for one utility (so $45,000/MW across all three utilities)?

That is correct.  The Bid Assurance Collateral in the draft Part 2 Proposal requirements requires providing a letter of credit to each utility in an amount that is based on the size of the project presented ($5,000/MW for wind, $15,000/MW for solar projects, subject to a $25,000 minimum).  The final requirements are expected to be posted on July 19, 2017.
