Replacement of Circuit Switch Data (CSD) Modems and related Telemetry Equipment (for use with Technolog Cello-MO Telemetry Systems)

Wales and West Utilities Ltd (WWU) operate a UK Gas distribution network, this is a notice to award a contract for provision CSD hardware within the Technolog Cello-MO Telemetry.

Pressure control is critical to reduce excessive pressure and leakage in the network ensuring safety and environmental risks are limited. Self-learning low pressure management and profiling is a key contributor to lowering gas emissions.

Ofcom have approved BT Openreach to remove wholesale line rental (PSTN Copper lines) in the UK by 2025 upon which the current gas control system relies and as such an alternative solution is required.

We require a self-learning, forecast and profiling solution with control equipment and supporting communications solution capable of varying the outlet pressure of the governor to suit network demand; pressures must follow a self-learnt profile to be raised at periods of high demand and decreased at periods of low demand automatically within safe limits
