When in the best interests of ratepayers, the Commission may direct investor-owned transmission and distribution utilities to enter into long-term contracts for:
Capacity resources contracted for under this Chapter may not exceed the amount necessary to ensure the reliability of the electric grid of this State or to lower customer costs. Unless the Commission determines the public interest requires otherwise, a capacity resource may not be contracted for under this Chapter unless the Commission determines that the capacity resource is recognized as a capacity resource for purposes of any regional or federal capacity requirements.
A long-term contract authorized under this section may be for physical delivery of the products or may be a financial transaction. The Commission may permit, but may not require, investor-owned transmission and distribution utilities to enter into contracts for differences that are designed and intended to buffer ratepayers in the State from potential negative impacts from transmission development.
