1. Background

This tender seeks a service provider for the needs of Miksei Oy, the development company of Mikkeli, and the City of Mikkeli during the term of the framework agreement. The tender will establish a framework arrangement with one supplier. The procurement relates to the investment promotion work carried out by the City of Mikkeli and its development company, which supports the municipality's statutory task of promoting the vitality of its region.

Expert support is needed for the preparation of investment projects, assessment of location possibilities, discussions and negotiations with grid operators, authorities, parties planning or preparing electricity-intensive investments, and other key stakeholders, as well as for decision-making support, if necessary, also in English. Such parties may include, for example, grid operators, the Energy Authority, permitting and supervisory authorities, and developers of investment projects that use or produce electricity significantly.

The objective of the procurement is to establish a framework agreement based on which clients can flexibly procure planning and expert services related to high and medium voltage grids.
