Nordisk turbinspecifikation för vattenkraft

This common specification aims to:

• Harmonize requirements: By agreeing on common technical requirements, power companies can streamline their internal procurement processes and facilitate comparisons between different suppliers.

• Reduce uncertainties: By clarifying requirements and expectations at an early stage, the risk of misunderstandings and delays during the project is reduced.

• Achieve cost efficiency: Unified requirements can lead to economies of scale and lower prices from suppliers.

• Foster innovation: By collaborating on technical requirements, power companies can better equip suppliers to develop new, innovative solutions.

• The NTTR specification is intended to be used for new turbines and turbine components, and it is not intended to cover all types of renovations or refurbished components.

• The structure of the technical specification for the NTTR is based on the IEC61366.

• The main focus is new turbines, however, since most projects will be refurbishments, there will be some sections included in the NTTR that is missing in the IEC61366, i.e:

• Fingerprint, measurements before dismantling

• The guide will at least initially focus on Kaplan and Francis units.

On this page the parts of the specification will be published as they have been produced.
