Objectives The project will explore whether controlling electrified residential heating in Scotland can be used to reduce the curtailment of renewable generation, without adversely impacting the distribution network. This desk-based study uses an area within the SSEN license area as a case study. The study will largely rely on excel-based technical modelling of the availability of flexibility from domestic electric heating and matching this with distribution and transmission network constraints. The study will also use further desk-based research to assess existing consumer perspectives on the potential use of domestic heating to provide flexibility services. It will build on learnings from various innovation projects that have already looked at aspects of electrification of heat.Further excel-based techno-economic modelling will aim to calculate the cost benefit analysis of using the flexibility of domestic heating compared to traditional solutions to manage constraints (curtailing renewable generation and network reinforcement). Lastly, potential business models to deliver these benefits will be explored based on desk-based research and analysis of existing business models, and potentially exploring new, novel business models. The project will examine and model the temporal and spatial nature of the ESO and DNO constraints limited to a representative area in the north of Scotland (SSEN license area – exact location to be identified as part of study). The available flexibility on the customer side of the meter will be analysed. The degree to which achievable flexibility from customer heating and ESO and DNO constraints match will be determined. The above will help investigate how onshore wind constraints can be partly mitigated through electric heat demand turn up and DNO network capacity issues can be partly mitigated by demand reduction.Appropriate business models required to drive customer behaviour will also be investigated. These analyses will be used to develop a detailed cost benefit analysis. The model will focus on current and potential future constraints. The potential benefits to the GB transmission and distribution systems are informed by what the ESO and DNO currently pay to alleviate constraints. These prices reflect the value to the ESO and DNO of constraint alleviation services. Specifically: Current and future ESO constraint costs.Current and future DNO constraint costs.There are 380k off-gas grid homes in Scotland. This is informed by Citizens Advice ScotlandTypical flexibility per homeCost of controls. Project objectives:Analyse how well DNO and ESO constraints match with available flexibility from electric heatingConduct cost benefit analysis (CBA) to identify if this is this cost effective, and how it scales up to all off-gas grid Scotland. 
Abstract The project will explore whether controlling electrified residential heating in Scotland can be used to reduce the curtailment of renewable generation, without adversely impacting the distribution network.
