Manually Activated Reserves Initiative (MARI) is the European implementation project for the creation of a European platform for the exchange of balancing energy from frequency restoration reserves with manual activation (mFRR), as required by the Electricity Balancing guideline (Commission Regulation (EU) 2017/2195), which defines tasks and a timeline for the implementation of the European mFRR platform. The MARI platform shall be capable of gathering offers for mFRR provision from participating TSOs’ local balancing market, and provide an optimised selection of reserves to cover the TSOs demands.
Amprion is not a contracting authority or sector contracting authority within the meaning of public procurement law. In the present case, Amprion is exceptionally issuing a public invitation to tender, as the service to be procured also meets the needs of other transmission system operators who are subject to public procurement law.
The optimisation module or AOF (activation-optimisation function) module of the platform refers to the module,
which solves the optimisation problem and provides the market clearing for the mFRR. As such, the module
is responsible for finding the most cost-efficient activation of mFRR bids to meet the TSO demands, while
considering constraints linked with the availability of the network. The service provider is expected to perform
software development of this module, as well as provide service and maintenance during ongoing operation of
this module of the platform.
The data management module is responsible most importantly for providing an interface for the national mFRR
energy markets. In this sense, the data management module is responsible for receiving all TSO demands and
bids for mFRR based on standard products and provide this information to the AOF module, which will perform
the optimisation and determine the satisfaction of balancing demands. Additionally, the respective available
capacities on relevant interconnectors are submitted by TSOs to the data management module and forwarded
by it to the optimisation module. The service provider is expected to perform software development of this
module, as well as provide service and maintenance during operation of this module of the platform.
