Medium Voltage Stations

Eskom provided the BioEnergy Atlas with a set of data to describe their current and planned infrastructure:
* High voltage transmission lines and substations;
* Medium voltage distribution lines and substations;
* Planned new transmission lines;
* Planned new substations.
All of these were aggregated to meso-zones (planning and analysis zones used for the Atlas) in the following way:
* Distribution and transmission lines: presence or absence of lines;
* Substations: count of medium voltage substations, and proximity (5km) to high voltage substations

Eskom向生物能源地图集（BioEnergy Atlas）提供了一组数据，用于描述其当前及规划中的基础设施，具体包括：
* 高压输电线路与变电站；
* 中压配电线路与配电变电站；
* 规划新建输电线路；
* 规划新建变电站。
所有数据均按如下规则聚合至中观分区（即该地图集所采用的规划与分析分区）：
* 输配电线路：仅标记线路的存在与否；
* 变电站：统计中压变电站的数量，以及其与高压变电站的5公里邻近性。
