Althio, The Netherlands’ Largest Tower Company Begins Operations
KPN and pension fund ABP have officially closed their tower infrastructure deal and launched Althio, a new Dutch towerco with regulatory approval from the Dutch Authority for Consumers & Markets.
Althio immediately becomes the largest tower company in the Netherlands, bringing together around 3,800 telecom and broadcast sites from KPN and Open Tower Company. The portfolio also includes unique rights to install telecom equipment on the country’s extensive high-voltage electricity network — a strategic advantage that strengthens national coverage.
As part of the transaction, KPN has reset and aligned key lease conditions across the portfolio to create a neutral, market-friendly platform for all mobile operators. KPN retains a 51% stake in Althio, following the global trend of operators owning majority positions in their towercos.
Althio will add 600 new Build-to-Suit (BTS) sites by 2034, expanding coverage and supporting long-term mobile and broadcast demand.
The creation of Althio gives KPN greater flexibility, stronger operational control, and significant synergies across development, maintenance, and network optimisation. The introduction of a single 20-year master services agreement covering 60% of the portfolio further streamlines operations and resets lease economics.
Overall, Althio represents a major step forward for the Dutch digital infrastructure landscape — a scaled, modern, neutral towerco positioned to support national connectivity for decades to come.
