Franchises
CL&P. Subject to the power of alteration, amendment or repeal by the General Assembly of Connecticut and subject to certain
approvals, permits and consents of public authority and others prescribed by statute, CL&P has, subject to certain exceptions not
deemed material, valid franchises free from burdensome restrictions to provide electric transmission and distribution services in the
respective areas in which it is now supplying such service.
In addition to the right to provide electric transmission and distribution services as set forth above, the franchises of CL&P include,
among others, limited rights and powers, as set forth in Title 16 of the Connecticut General Statutes and the special acts of the General
Assembly constituting its charter, to manufacture, generate, purchase and/or sell electricity at retail, including to provide Standard
Service, Supplier of Last Resort service and backup service, to sell electricity at wholesale and to erect and maintain certain facilities on
public highways and grounds, all subject to such consents and approvals of public authority and others as may be required by law. The
franchises of CL&P include the power of eminent domain. Title 16 of the Connecticut General Statutes was amended by Public Act 03-
135, "An Act Concerning Revisions to the Electric Restructuring Legislation," to prohibit an electric distribution company from owning or
operating generation assets. However, Public Act 05-01, "An Act Concerning Energy Independence," allows CL&P to own up to 200
MW of peaking facilities if the DPUC determines that such facilities will be more cost effective than other options for mitigating FMCCs
