The Rhode Island State Public Utilities Commission is set to vote on a proposed 24 percent electric rate increase.
Officials are scheduled to meet at 10 a.m. Tuesday to vote on National Grid's request.
If approved, the monthly bill for a typical household in Rhode Island would increase from $88 to $109. Critics say the increase is too much.
National Grid says as long as it has followed all the procedures, the Public Utilities Commission should sign off on the plan. The utility says the rate hike is due to higher demand for natural gas, with more power plants burning natural gas to generate electricity.
If approved, the rate increase will take effect in January.
