The object of the overall project “Future Charlottenburg” (FchB) is the construction of a cogeneration plant (CHP plant) consisting of a two-line gas turbine plant with waste heat boiler and a P2H plant.

The aim of the overall project is that the new plants have a total generation capacity of at least 240 MWth (including approx. 80-110 MWth via a P2H system) and at least 100 MWel.

This goal is to be achieved by constructing a two-line gas turbine plant with waste heat boiler and a P2H system (electrode hot water boiler/e-HWE with total output of approx. 80-110 MWth). The best use of available space by the bidders is essential for the issuing body in this regard (see spatial conditions under II.2.4)). Both new plants are expected to replace the old plants currently in operation. The new plants are to be erected on the property of the Charlottenburg heat and power plant (Am Spreebord 5, 10589 Berlin) in an existing and largely gutted building, which formerly included a flue gas desulphurization plant (REA). The new plants must be integrated into the existing infrastructure and fit into the existing spatial conditions of the existing building. The cogeneration plant must also be able to operate on hydrogen in the future. The pre-planning has already been completed and the project is in the approval phase.

With this announcement, the Power Island will be advertised as Lot 2 for the project “Future Charlottenburg”.

In addition to the aforementioned lot 2, the issuing body intends to award the subsequent execution into 4 further partial lots:

- Lot 1 general planner (to support the AG in processing)

- Lot 3 construction (execution planning, all structural engineering measures including turbine foundation)

- Lot 4 EPC Light (waste heat boiler, district heating connection, control and e-technology)

- Lot 5 E-HWE

Lot 2 “Power Island” announced here includes the planning, production, installation and commissioning of two gas turbines (functional including filter house, exhaust gas diffuser, ancillary systems and component control technology), fuel gas compressors, machine transformers (including connection to the 110kV distribution network) (summarized in hereinafter referred to as “Power Island”).

The issuing body points out that the project's goal for the construction of at least 240 MWth, including approx. 80-110 MWth via the P2H system) and at least 100 MWel must be achieved across all lots.

The generation capacities indicated are minimum values.

Offers from bidders that achieve significantly higher thermal and/or electrical performance taking into account the spatial requirements are expressly permitted.

Spatial requirements: The two gas turbine strands must be placed next to each other. In existing construction, a length of approx. 25 m and a clear width of approx. 14.5 m is available from the entrance to the hall. The hall height in the front area is limited to 23 m by a mezzanage to approx. 9 m in the back area. The filter houses can be installed on the intermediate stage or above the hall in existing construction. The foundations of the turbine lines are established in the basement at 4m, so that the base frames are up to 0 m. More details can be found in the procurement documents.

For the scope of lot 2, part of the procurement is also a long-term maintenance contract (hereinafter referred to as “LTSA” (Long Term Service Agreement)).

The (total) power is divided into the partial power “Power Island” and the partial power “LTSA”. Nevertheless, it is common in the industry to jointly evaluate the partial performances “Power Island” and “LTSA” when considering the cost-effectiveness of such services. Following this, the overall cost-effectiveness of an offer via the “Power Island” and “LTSA” is evaluated in the quotation process when deciding on the most economical solution. Therefore, it would be pointless to split more lots. More information will be found in the procurement documents.

In order to reflect the respective responsibility of partial services fairly, a contract for the “Power Island” and a separate contract for the “LTSA” should be concluded — customary in the industry. It is possible to conclude two contracts with a company that offers both service parts (contracts) separately in one offer. It is also possible for one or more members of the bidding community to take over the “Power Island” in a bidding community (i.e., the respective member concludes the Power Island contract) and one or more members of the bidder community will take over the “LTSA” (i.e., the respective member closes the LTSA). For more information see also: III.1.8.) It is excluded from offering the total service (Power Island and LTSA) in just one contract from one company. The offer of partial service by a company (e.g. “Power Island”) that provides for a subcontractor for a further partial service (e.g. “LTSA”) is also excluded. The client wants to directly select and contract with the person who is responsible for the respective partial performance.
