Minnesotans who get their electricity from Xcel Energy Inc. could be facing four more years of rate increases.
Despite rate hikes in each of the past three years, the utility serving 1.2 Minnesota electric customers says it needs to collect more revenue to cover $1 billion a year of investments in Xcel's system.
Executives disclosed Thursday that Xcel wants to spread out the pain of its next request for a "significant" boost in rates, which it plans to file next month. Under a strategy called "rate smoothing" or "rate moderation," Xcel would forgo a giant increase in 2014, in favor of a series of smaller increases over several years.
"I think you are going to find our rate moderation plans to be in that zone of reasonableness," CEO Ben Fowke said on a conference call with stock analysts about its third-quarter results.
The Minneapolis-based utility didn't release complete details Thursday. It has signaled since August that it will seek a sizable multiyear rate increase. In its most recent Minnesota rate case, Xcel requested a 10.7 percent increase, but regulators concluded that wasn't reasonable and slashed it to 3.8 percent. That came after two smaller rate increases were approved for Xcel in 2011 and 2012.
Now the company says it will offer a rate moderation plan with its requested 2014-2015 increase to be filed with the state Public Utilities Commission, which sets rates for investor-owned utilities. In a presentation to the PUC this month, Xcel suggested spreading out the rate hikes over four years through 2017, with bigger increases in the second and third years.
Yet a series of single-digit increases still can add up to a double-digit increase over time, which is sure to be a concern of ratepayer interest groups.
"We will have to see the details first," Pam Marshall, executive director of the Energy Cents Coalition, a group that advocates on behalf of low-income ratepayers, said in an interview Thursday.
