Draft Base Exclusions (Solar) for 2026-2027 IRP

This version of the base exclusions incorporates the latest draft version of the Protected Area Layer (Solar) and the techno-economic exclusion layer. The base exclusions form the fundamental exclusion set that the additional planning priorities of the Core Land Use Screen is added to. The merged footprints of these primary two layers are modified by the Greater Sage-Grouse Habitat Management Areas, the Bureau of Land Management Desert Renewable Energy Conservation Plan (DRECP) Land Use Plan Amendment (LUPA) Development Focus Areas (DFAs), Variance Process Lands (VPL), and the General Public Lands (GPL), as well as the 2024 BLM Western Solar Plan. These areas allow for renewable energy applications and are therefore exempt (erased) from the base exclusions layer, even if the protected area layer or techno-economic exclusion layer identified the area as an exclusion. The DFAs are partitioned by technology type so that only the DFAs that allow solar energy are applied in this modification. The area of California remaining after removing the base exclusions is called the resource potential basemap. It forms the starting point (or base) used in renewable resource estimation and defines where environmental and land-use datasets can be applied in exploring implications of renewable resource development. Note: Existing project footprints are also included as part of the base exclusions. More information is found in the CEC presentation from the August 19 webinar, as well as the 2023 Land Use Screens Staff Report in the CEC Energy Planning Library.本版基础排除集纳入了最新草案版本的太阳能用保护区图层（Protected Area Layer (Solar)）与技术经济排除图层。基础排除集构成了核心土地利用筛查（Core Land Use Screen）新增规划优先级所依托的基础排除集合。上述两个核心图层的合并覆盖范围，将通过大艾草松鸡栖息地管理区、美国土地管理局（Bureau of Land Management, BLM）沙漠可再生能源保护计划（Desert Renewable Energy Conservation Plan, DRECP）土地利用计划修正案（Land Use Plan Amendment, LUPA）开发重点区域（Development Focus Areas, DFAs）、审批流程用地（Variance Process Lands, VPL）、公共通用用地（General Public Lands, GPL）以及2024年BLM西部太阳能计划进行调整。上述区域允许开展可再生能源开发申请，因此即便太阳能用保护区图层或技术经济排除图层曾将该区域标记为排除区域，其仍可豁免于基础排除图层，即从该图层中移除对应区域。开发重点区域（DFAs）按技术类型进行划分，因此本次修改仅纳入允许太阳能开发的DFAs。移除基础排除集后剩余的加利福尼亚州区域被称为资源潜力底图。该底图作为可再生资源评估的起始基准，明确了可用于探索可再生资源开发影响的环境与土地利用数据集的应用范围。注：现有项目占地亦纳入基础排除集范畴。更多详细信息可参阅8月19日网络研讨会中的加州能源委员会（California Energy Commission, CEC）演示材料，以及CEC能源规划库内的《2023年土地利用筛查工作人员报告》。
