65- 407 C.M.R. ch. 307, § 8
Purchasers of capacity and energy sold pursuant to this Chapter shall pay utilities for capacity and energy each month, not later than 20 days after the close of the billing period established in the contract between the utility and the purchaser unless the utility and the bidder agree upon a more rapid payment schedule.
If a purchaser of capacity and energy fails to make required payments to the utility or otherwise defaults in its obligations, and such default is material, the utility shall immediately notify the Commission. The utility shall engage in reasonable business practices in addressing the default. In the event of a default, the utility may sell the capacity and energy to an alternative purchaser or in the regional wholesale bulk power markets. The utility may not sell to an alternative purchaser pursuant to a contract term that extends beyond the expiration of the current sales period as established in section 7(E) without the prior approval of the Commission.
