Replacement of PSTN Lines and related Telemetry Equipment (for use with Gas Controllers)

Wales and West Utilities Ltd (WWU) operate a UK Gas distribution network, This is a notice to award a contract for provision of Telemetry Hardware Equipment and associated digital communications required to profile and control a low pressure gas network without the use of copper phone lines or mains power.

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. Logger data at low point extremities must feed into the profiling solution over a reliable communications solution without the use of copper phone lines PSTN
