Interruptible loads

Backgroung, prequalification and contracts

Background

With the amendment of the Energy Industry Act (EnWG) of 20 December 2012, on the part of the legislator, opportunities were created with Section 13 paragraphs 4a and 4b to impose a contractual obligation on interruptible loads, for the maintenance of network and system security. In order to provide criteria for the meaningful application of this from a technical and economic point of view, appropriate conditions were specified in the regulation on agreements on interruptible loads (German abbreviation: AbLaV).

In terms of this regulation, interruptible loads are major consumption units connected to the high and ultra-high transmission grid (at least 110kV voltage level). Those units are characterized by drawing large amount of electricity at any time and can quickly reduce their consumption of power according to the actual frequency or remote controlled for a certain period of time.

In accordance with the AbLaV, the German transmission system operators will organize a monthly tender for a total capacity of 3,000 megawatts. Each supplier with interruptible capacity that meets the technical requirements of Sections 5 to 7 of the AbLaV is entitled to participate in the tender process. This has to be demonstrated as part of the prequalification process.

The regulation on agreements on interruptible loads can be downloaded under the following Link (in German):

Prequalification

The connecting transmission system operator shall enter into national framework agreements with suppliers of interruptible capacity from interruptible loads in its control area, in accordance with the AbLaV. In the pre-qualification process, the supplier has to demonstrate that the consumer facilities meet the prequalification requirements of the transmission system operator based on the AbLaV.

The common prequalification requirements of the German transmission system operators can be downloaded on the right side of this page (German language only).Only suppliers who have concluded a framework agreement as part of the prequalification process are entitled to participate in the tender process.

Please contact us if you are interested in taking part in the pre-qualification process.
