CMLP uses Time-of-Day net billing: exported solar is credited at the applicable TOU rate, so generation during the 3-7pm peak period is worth significantly more than off-peak. When a month credits exceed charges, the excess rolls over to the next monthly electric bill (or, if the electric account is bundled with other town services in an "invoice group," the credit is applied to those other services that month). Any year-end excess (CMLP notes this is highly unlikely) is paid out by check to balance the account, not forfeited.
