Sweden – Electrical Supply Facilities – Station Upgrades, Phase 2

Sundsvall Elnät AB is seeking to partially renew and renovate two existing 130/10 kV substations: M8 Granloholm and M50 Birsta. Transformers for the receiving stations have already been procured and will be delivered during the construction period by another contractor. The procurement includes the renovation of the two existing receiving stations M8 and M50. The renovation consists of earthworks, a new control building, a renewed 130 kV switchgear, additional 10 kV compartments with associated new control systems, telecommunication systems, local power and auxiliary power systems, as well as oil pits for transformers. E.ON Energidistribution AB's 130 kV components in M50 mainly include: new switchgear portals, new busbars, new cable compartments, and associated control systems. The procurement process occurs in two stages, with stage 1 (this request) involving a qualification phase for interested bidders. Subsequently, in stage 2, qualified bidders will receive the tender documents for further bidding and will later be invited to a bid review. The distribution of the tender documents to qualified bidders is planned for early January.
