This guide is primarily concerned with the grounding system design for photovoltaic solar power plants that are utility owned and/or utility scale (5 MW or greater). The focus of the guide is on differences in practices from substation grounding as provided in IEEE Std 80. This guide is not intended for the substations to interconnect the plant; however, if the substation is included within the plant, portions of this guide may be applicable. Similarly, this guide does not directly cover small scale solar power plants (such as rooftop type systems), substation grounding, or lightning protection.

IEEE Guide for Wind Power Plant Grounding System Design for Personnel Safety
The collector system grounding for wind power plants (WPPs) is the primary concern of this guide. This guide is not intended for the WPP substation; however, since the substation is typically interconnected with the collector system, its design might affect or be affected by the collector system. With proper consideration, the methods described herein could be used in determining the impact of the collector system on substation safety and vice versa. Quantitative analysis of the effects of lightning surges is beyond the scope of this document. Similarly, this guide does not cover offshore wind power plants, battery energy storage facilities, solar power plants, or substation grounding
