Turbine Supply Agreement Definition

The turbine supply contract required a credit for the purchase price of the wind turbines minus the reservation payments for the turbines. Operating expenses (« OPEX ») can represent 25-30% of the total life of a wind farm, even more so when it is an offshore investment value. The majority of these costs are under a single contract – the turbine service and maintenance contract (hereafter the SMA). Given the significant impact of ADM on the entire owner`s business case, it is essential to have a well-defined and optimized contract. This article examines the ADM contract from the owner`s perspective and addresses the important issues that often arise during negotiations. The TSA generally covers the construction, construction and delivery of these components on site, as well as the assembly, commissioning and warranty of each WTG. The form of the TSA may be a custom form or a modified standard form, but it is adapted to the specific requirements of wind turbine supply contracts. Repowering projects can be either full repowering projects or partial repowering projects. In a full-fledged repowering, the old turbines, foundations and electrical installations are closed, demolished and removed from the project, and new turbines are built on new foundations specially designed for the new turbines. When new collection and control circuits are added, the reintroduced site is able to extend the life of a project by at least an additional 10 years.

Developers are able to reuse previously constructed access roads, pavements and sleeping surfaces, and equip substations and common facilities instead of building new facilities, reducing the total cost compared to a new production facility in green grasslands. Spare parts and tools are often overlooked. How do you ensure that spare parts can be delivered during and after the ADM period and at what cost? Does the owner need to acquire a first stock of spare parts? Or is a time pricing concept the right solution? As an owner, you must ensure that the price of spare parts is agreed under the ADM and that the supply of spare parts is safe for the life of the asset. Project proponents can also perform partial repowering to update existing wind projects with equipment that increases power generation, reduces machinery load, increases network service capacity and improves project reliability. A partial repower project involves the integration of new parts and modernized equipment into the existing project infrastructure. In many cases, a turbine supplier has developed an upgrade kit for existing turbines to improve the capacity and efficiency of existing facilities. These modifications are usually in the form of the installation of new shovels, rotors, drive shafts and control systems when reusing the tower and existing foundations. With the increased capacity of the driven turbines, the developer may also be required to upgrade the existing electrical system and substation. Integrating existing infrastructure with new equipment can face a number of challenges.

First, the existing infrastructure, including towers and foundations, must have sufficient structural integrity to support the load profile of the new turbines. If the wind regime is aggressive on the project site, the load on existing foundations may have reduced the structural integrity of the foundations, making existing foundations unsuitable for repowering without costly upgrades. A second consideration is to obtain adequate protection. While new turbines and modernized electrical equipment are generally equipped with a manufacturer`s warranty, guaranteed protection may be compromised if damage to the covered equipment is caused by a failure of the original equipment or infrastructure.
