(Providence, RI) -- National Grid is proposing a settlement with the Rhode Island Public Utilities Commission regarding gas and electric rates. The utility is now requesting about half of the rate increase it asked for in late 2017 for the first year of a three-year plan, which would hike residential electric bills up by about four percent, followed by increases of about half a percent in the second and third years. For residential gas customers, bills would go down slightly in the first year, and then rise one-and-a-half percent in the second year and zero-point-nine percent in the third. The utilities commission must still approve the proposal.
