Unitil Corp. asked the Maine Public Utilities Commission for approval to raise its natural gas distribution base rates by $7.0 million to recover continued infrastructure investments for safety and reliability improvements.
The proposed rate hike of about 7% over total 2018 operating revenue could add approximately $9.90 per month, or about 9.3%, to a typical residential customer's monthly bill, according to a June 28 news release. The new rates would take effect Aug. 1 if approved by the commission. The utility, however, expects a commission suspension period until April 1, 2020.
Also included in Unitil's filing is a proposal for an alternative rate mechanism called the capital investment recovery adjustment, which would enable the utility to recover costs related to non-growth capital projects, including relocations, upgrades or replacements of existing distribution facilities.
Unitil is a public utility holding company serving about 82,700 natural gas customers. The utility operates in Maine, New Hampshire and Massachusetts.
