What happens at the end of a 15 year National Grid REGrowth tariff contract?

I got two bids from an installer based on two different incentives programs. One had a credit from the RI renewable energy fund and then assumed net metering rates projected out 25 years. The second quote was based on the National Grid Renewable Energy Growth Program, and for the first 15 years it assumed income from the tariffs, but then after the 15 year mark the savings on energy that they carried were less than the savings that they assumed using net metering.


RI Fund plan with net metering, year 16: electric w/o solar - 1538, electric w/ solar - 241, Savings - 1298.

NGrid REGrowth after tariffs, year 16: electric w/o solar 1538, electric w/ solar 908, Savings 630.

I would have assumed that after the tariffs ran out I could switch over to net metering and that my projected savings should match up from years 16 on, but I'm not sure if there's a reason why this wouldn't occur.

According to National Grid, customers on the REGrowth tariff will be able to switch over to whatever solar program National Grid is offering when their REGrowth contract ends – that may or may not be net metering. By comparison, if you sign up for net metering now you are guaranteed net metering rates for the term of the contract.
