BOULDER - Xcel Energy Inc. has kicked in another $200,000 toward the campaign for Boulder ballot Issue 310 relating to the city's attempt to break away from Xcel and create a municipal electric utility.

That's based on the latest election fundraising and spending reports filed with the city clerk's office on Thursday. Final reports are due within 30 days after Tuesday's election.

Xcel now has donated $500,000 in all to the issue committee Voter Approval of Debt Limits, which gathered the necessary voter signatures needed to place 310 on the ballot.

Issue 310 calls for voter approval of a municipal utility's debt limit and the total cost of debt repayment. It also would require that the utility's service area not extend beyond city limits unless customers outside the city are allowed to vote in such elections, which could be held only in odd-numbered years during general municipal elections.

The Boulder City Council in August placed a competing measure on the ballot, 2E, which would place a limit of $214 million only on the amount of debt that could be issued for the acquisition of Xcel assets needed to operate the city-run utility, as well as any stranded costs incurred by Xcel.

Voter Approval of Debt Limits has raised $522,100 in all and spent $512,840. Its Thursday filing notes that it anticipates raising another $195,000. Xcel's own issue committee, in addition to donating the $500,000 to VADL, has spent another $31,147, much of that going toward staff time spent working on the campaign. Xcel's issue committee report shows another $196,036 in anticipated expenditures.

Four groups opposing 310, who argue that it would cripple municipalization efforts, now have raised a total of $341,414. The largest chunk of that is the $230,723 raised by New Era Colorado's issue committee, although that group raised no more money in the recent reporting period. New Era has spent $190,470 so far.

The Sierra Club chipped in about $30,000 in the latest reporting period: $2,300 to Boulder's Clean Energy Future, $15,400 to Empower Our Future and $12,300 to the local Sierra Club Indian Peaks Group, which spent more than $14,000 over the last week on anti-310 advertising.
