A contract dispute between Portland and CMP has left two dozen streetlights dark, the Press Herald is reporting.

The disagreement is over who has to pay to fix underground power conduits and that has stalled the repair of the streetlights for up to six months, according to the story.

CMP is saying the city is responsible for the repairs, the Press Herald reports, while Portland is claiming it's Central Maine Power's responsibility.

Now state regulators are accepting public comments on regulations to clearly make municipalities responsible.

In the meantime, residents in Portland's northwest corner haven't had working streetlights since last fall, according to the paper.
