Remaining Performance Obligations

Remaining performance obligations primarily represent lighting contracts and gas transportation contracts with fixed contract terms. As of December 31, 2021 and 2020, the aggregate amount of the transaction price allocated to remaining performance obligations was approximately $135 million. This amount includes $112 million of future performance obligations related to a gas transportation contract between SeaCoast and PGS through 2040. As allowed under ASC 606, this amount excludes contracts with an original expected length of one year or less and variable amounts for which TEC recognizes revenue at the amount to which it has the right to invoice for services performed. TEC expects to recognize revenue for the remaining performance obligations through 2041.
