GALVESTON — The city is reviewing whether it’s getting what it pays for when it comes to streetlights.

At issue is a little known tariff imposed by CenterPoint Energy for the amount of light that’s supposed to shine from each streetlight bulb. The tariff is embedded in the bill the city receives from its retail electric provider, Cavallo Energy.

The review comes after The Daily News began asking questions last month about whose responsibility it is to maintain streetlights and how much the city pays for them.
