Hudson Light and Power Department and Peabody Municipal Light Plant1 (the municipalities) claim that they were induced to purchase power through MMWEC based on MMWEC’s promises and representations that it would enter into and enforce a sellback agreement with the Public Service Company of New Hampshire (PSNH).2 MMWEC and PSNH entered such an agreement (the sellback agreement), but they expressly retained the right to modify it. Financial difficulties and disputes led to litigation between MMWEC and PSNH, including PSNH’s filing for bankruptcy protection, which resulted in a settlement under which MMWEC released PSNH from its obligations under the sellback agreement. See Public Serv. Co. of N.H. v. Hudson Light & Power Dep’t, 938 F.2d 338, 339 (1st Cir. 1991). The municipalities argue that they are entitled to damages for MMWEC’s failure to abide by its promises and representations by waiving the sellback agreement. We do not agree.

In their counterclaim and affidavits, the municipalities offered no proof of a promise or representation by MMWEC that MMWEC would assume the risk in the event that enforcement of the sellback rights became impossible.3 See Massachusetts Mun. Wholesale Elec. Co. v. Danvers, 411 Mass. 39, 51 (1991). See also Public Serv. Co. of N.H., supra at 345. At most, all that could have reasonably been relied on from MMWEC’s alleged promises and representations was that MMWEC would enforce the sellback agreement as long as it could. MMWEC did this. At the time MMWEC released PSNH from the sellback agreement, MMWEC could no longer enforce the agreement in view of PSNH’s pending bankruptcy. We conclude that the claims cannot survive MMWEC’s motions for summary judgment. The decision of the Superior Court judge granting MMWEC’s motions for summary judgment is affirmed.

So ordered.
