Utility Solar Generation Regions: 2022

The map depicts Solar Generation Regions of California, which
are regions with concentrations of operating commercial solar
plants. The regions were delineated using a k-means method
that groups the plants into discreet regions based on their
latitude, longitude and distance to the coast. After facilities
were grouped, the outermost facilities in each region were
connected to create the boundaries for each region. To include
all facilities inside each polygon, a 5 km cartographic buffer was
used. Plants that are farther from a concentration of other
plants are not included. Areas outside California included in the
regions are the result of the mapping process and do not
represent solar generation facilities. Based on the Quarterly
Fuel and Energy Report dataset, this map focuses on plants of
commercial scale (at least 1 MW capacity).

本地图展示加利福尼亚州太阳能发电区域（Solar Generation Regions），即商业运营太阳能电站的集中分布区域。
该区域通过k均值聚类（k-means）算法划定，基于电站的纬度、经度及与海岸的距离，将电站划分为离散区域。
完成电站分组后，将各区域内最外围的电站进行连线，以此生成各区域的边界范围。
为确保所有电站均被纳入对应多边形范围内，本次制图采用了5公里的缓冲区。
与其他电站集群距离过远的电站将不被纳入本次统计范围。
区域中包含的加利福尼亚州境外区域，系制图流程所致，并非实际的太阳能发电设施分布区域。
本地图基于《季度燃料与能源报告》（Quarterly Fuel and Energy Report）数据集制作，聚焦于商业规模（装机容量不低于1兆瓦）的太阳能电站。
