It is intended that, as a result of this Procurement, CoLC will enter into a development agreement under which the Heat Network Development Partner (via the special purpose vehicle (the “SPV”) established for development and delivery of the Network) is required to design and develop the Network up until the point at which it is ready to be built, at which point, it will present the project for approval by CoLC.
