TransnetBW order for “bnBm” gas power plant

20.08.2019

TSCNET Services shareholder TransnetBW, one of the four German transmission system operators (TSOs), has awarded Energie Baden-Württemberg AG (EnBW) the contract for the provision of a “special network equipment” (“besonderes netztechnisches Betriebsmittel”, bnBm). EnBW will construct and operate a gas turbine power plant with a capacity of 300MW at Marbach. The city is the birthplace of the poet Friedrich Schiller and is located about 20 kilometres north of Stuttgart on the Neckar River.

The special network equipment will not be available to the market, but will be used from 1 October 2022 as a “safety buffer” exclusively at the request of TransnetBW to ensure safety and reliability in the transmission grid. It thus serves as a further reserve for the safety and reliability of the electricity supply system.

“Behind us lies a demanding tendering procedure, because we had to procure a completely new product,” says Dr. Rainer Pflaum, Managing Director of TransnetBW. It was about access to a capacity that “helps to stabilise the power grid flexibly and reliably”. The new plant would be an important component for supply security in the region.

Together with the TSOs Amprion and TenneT, TransnetBW issued a call for tenders for the special grid technology equipment with a total volume of 1,200MW open to technology and Europe-wide at the end of June 2018. Altogether, the tenders cover four regions in southern Germany, each with a capacity of 300MW.

TSO conditions for reserve capacity approved

05.08.2019

The four German transmission system operators (TSOs), the TSCNET shareholders 50Hertz, Amprion, TransnetBW and Tennet, the Dutch-German TSO, ensure the supply of electricity under all circumstances and thus hold reserve capacities as ultima ratio for unforeseeable and exceptional extreme situations on the electricity market. The reserve capacity is calculated at 2GW and the facilities to provide the capacity are determined every two years by the TSOs through a tendering procedure.

Last week, the Bundesnetzagentur (German Federal Network Agency) approved the new standard conditions for the reserve capacity which had been drafted by the TSOs. The standard conditions are the basis of the contractual relationship between the respective TSO and the operator providing the capacity. They are designed to be as transparent as possible and include, among other things, rules on the availability and use of the reserve system, remuneration or contractual penalties.

Due to the standard conditions, the potential participants in the tender procedure know the terms under which the reserve facilities must be operated and the legal consequences in case of failure of a plant. Now that the conditions have been approved, the tender for the first performance period can start as planned on 1 September 2019.
