Prior to 2005, a large number of efforts were made at federal level and in the various Länder to develop fair and uniform connection standards to facilitate the use of decentralised generation. The Texas Public Users Commission (PUC) adopted in December 1999 final rules (Project No. 21220) dealing with technical and contractual issues related to the installation of distributed resources. Texas standards place the burden of proof on the distribution company to determine whether an interconnection should not be allowed. The Commission has adopted a standard interconnection agreement and a standard tariff interconnection form. In February 2001, the PUC published the final version of its generational interconnection distribution (Project No. 21965). Although the interconnection application may be deferred, for example, to the end of the design phase, you may wish to contact your distribution undertaking much earlier in the process, (a) identify unique circumstances that would affect the feasibility and cost of interconnection, and (b) obtain interconnection authorisation as soon as possible. An additional potential benefit for some small generators is the possibility of reselling electricity to the distribution company. In Massachusetts, some generators are eligible for Net Metering, where the customer receives a payment for unused electricity that is reintegrated into the distribution system. The size threshold for the net measurement varies; For some technologies and situations, for example, net metering can be allowed up to 2 MW.
Authorization varies by technology and project owner. For public facilities that install wind turbines or solar installations, the ceiling is 2 MW per unit. For private companies that install wind or solar, the ceiling is 2 MW per project. In some cases, larger generators may also enter into electricity capture contracts with their distribution company. How do I request Net Metering? A customer requests Net Metering by completing Schedule Z in the power line rate. Public bodies must also apply to be classified as a public body. You can find the form here. At the end of each month, local generation is charged to the electricity consumed by the customer on the grid. If the customer has excess net production at the end of the month, the customer receives a credit on their electricity bill. How does the process work? It is the customer`s responsibility to initiate the interconnection review process by submitting an application to the local distribution undertaking serving the intended production site.
The application form depends on the size and nature of the project and its location. Once you have submitted a complete application and the fee indicated, the utility begins the verification. The utility may contact you at different locations during the process to obtain additional information or to inform you that the project has passed or failed at any of the verification steps. A project follows one of three audit trails (simplified, accelerated, or standard), depending on how it is produced and sized, customer load, and the characteristics of the network in which the generator is to be located….
