The Project Proponent also enters into a Plant Balance Agreement with an experienced contractor under which the Contractor plans and constructs other facilities required for the Project, such as turbine foundations, roads, crane platforms, sleeping areas, collection systems, substations, transmission lines and maintenance facilities. The contractor will also receive, inspect, unload and install the turbine equipment. In the relevant agreements, care must be taken to ensure that the scope of work and the appointment interfaces between the turbine supplier and the contractor are carefully coordinated. The agreement must avoid interference, duplication or omissions between the scope of work of the turbine supplier and the rest of the operator and ensure that the agreements together result in a fully designed, integrated and operational project. Depending on the complexity of the project, the project proponent may wish to enter into an interface agreement with the turbine supplier and the plant balance contractor to carefully coordinate the execution of each party`s scope of work. Close coordination between the turbine supplier and the plant manufacturer`s balance sheet reduces the likelihood of construction and commissioning delays. In this example, a project developer wants to purchase wind turbine generators (owned by design) and use the services of the wind turbine supplier to commission the wind turbine generators. The developer also wishes to enter into a contract with the turbine supplier to provide certain operation, maintenance and warranty services. The wind turbine supply contract required a letter of credit for the purchase price of the wind turbines less wind turbine reservation payments. Project developers can also perform partial repowering, which allows existing wind projects to be upgraded with equipment that increases energy production, reduces machine loads, increases grid service capacity, and improves project reliability. A partial repowering project involves the integration of new parts and improved equipment into the project`s existing infrastructure.
In many cases, a turbine supplier has developed a retrofit kit for existing turbines to improve the capacity and efficiency of existing equipment. These changes typically take the form of installing new blades, rotors, drive shafts and control systems while reusing the existing tower and foundations. With the increase in the capacity of the recharged turbines, the developer may also be required to perform upgrades to the existing electrical system and connection station. Integrating existing infrastructure with new devices can lead to a number of challenges. First, existing infrastructure, including towers and foundations, must have sufficient structural integrity to support the load profile of new turbines […].
