This section should set out the Method or Methods that will be used in order to provide a Solution to the Problem. The type of Method should be identified where possible, eg technical or commercial.For RIIO-2 projects, apart from projects involving specific novel commercial arrangement(s), this section should also include a Measurement Quality Statement and Data Quality Statement.The project will be split into 3 tasks, intended to maximise opportunities to collect and evaluate a hazard identification and risk assessment of gas alternatives.Task 1: DNV to prepare materials for the workshop e.g. scoping of scenariosWorkshop including hazard identification to be held.Task 2: Gap Analysis- DNV to review workshop outputsTask 3: Risk predictions DNV to draft final report This project covers the alternatives to distributed gas system and usage up to but excluding Local Transmission System across Great Britain.All common types of alternatives energy solutions are in scope, including electrification, solid fuel burners, and liquid petroleum gas (LPG), for heating and cooking only. Process uses are not in scope.The project will need to acknowledge many risks are related, such as safety, economical, environmental, and reputational. However, only risk to safety is to be assessed (unless, by close dependency, other risks needs to be commented on to fully explore safety risk). The key objective of this project will be to provide a safety assessment which covers the following areas:-The safety risk of differing energies security and resilience (e.g. on critical public-service buildings such as hospitals, and other national infrastructure)-The safety risk of slow re-energisation of heat (e.g. following energy interruption, linking to Excess Winter Mortality and electrics vs gas instantaneous heat outputs)-Safety risk of physical harm (electrocutions, explosions, fires, CO poisoning, etc.) of different energy vector appliances (e.g. electrical appliances, solid fuel/LPG heating)-Safety risk associated with theft of different energy (or rather the risk of improper use of alternative energy vectors).

This project will produce a Safety Assessment report to cover a non-distributed gas Great Britain energy system and usage scenario. This work builds on previous work as part of the GB QRA project (NIA_CAD0096) where the risk across Great Britain was quantified for hydrogen distribution and utilisation in the network, in houses, flats, and non-domestic buildings. The previously modelled scenarios included the application, or increase in application, of gas alternative solutions for cooking and heating. These could be electrical and other hydrocarbon fuel appliances. This project seeks to identify and qualify any risks introduced as a result of these gas alternative solutions on a national and individual scale.
