Heat networks in Brittany

Installations of district heating networks (RCU) in Brittany (deliveries in GWh, weight of consumption sectors and share of energy sources of heat). **Sources:** Annual survey on heating and cooling networks (SDES), Wing (instructions files), Rennes Métropole ("Service Réseaux d'Energies et de Chaleur (SREC)"), Brest Métropole, ODRE registry, Sinoe, Cerema (RCU 2018 survey). **Processing notes:** - The main source for updating heat delivery data is the ERCF, but it only addresses one third of the networks identified by the EPO. - A great deal of research and verification has been undertaken by the EPO to establish as comprehensive a reference system as possible, with the year of commissioning, the users and the detailed characteristics of the networks. - Heat deliveries from networks not listed in the SDES local energy data are estimated on the basis of calculations carried out as part of the processing of heat production data from wood boilers, gas cogeneration, IOMs, and LNG carriers connected to UCRs (see the methodology for processing energy production data in the datavisualisation <a href="https://bretagne-environnement.fr/tableau-de-bord/la-production-energie-bretagne" target="_blank">"Energy production in Brittany"</a> carried out by the EPO. - For the public networks of Rennes Métropole and Brest Métropole, data are transmitted directly to the EPO by the services.布列塔尼地区区域供热管网（RCU）数据集，涵盖以吉瓦时（GWh）计的供热量、各消费板块占比及供热能源来源占比。 **数据来源：** 供热供冷管网年度调查（SDES）、Wing（指令文件）、雷恩大都会区（"能源与热网服务处（SREC）"）、布雷斯特大都会区、ODRE注册库、Sinoe、Cerema 2018年RCU调查。 **数据处理说明：** - 供热供热量更新的核心数据源为ERCF，但该数据集仅覆盖EPO所识别管网的三分之一。 - EPO已开展大量调研与核验工作，以构建尽可能全面的参考体系，涵盖管网投运年份、服务用户及管网详细特征。 - 对于未纳入SDES地方能源数据的管网供热供热量，将基于木材锅炉、燃气热电联产、工业余热装置（IOMs）以及接入UCR的液化天然气运输船相关热能生产数据的处理计算结果进行估算；具体方法可参阅EPO制作的布列塔尼地区能源生产数据可视化页面 <a href="https://bretagne-environnement.fr/tableau-de-bord/la-production-energie-bretagne" target="_blank">"布列塔尼能源生产"</a> 中的能源生产数据处理方法论。 - 针对雷恩大都会区与布雷斯特大都会区的公共管网，相关数据由当地主管部门直接报送至EPO。
