Turkwel reservoir is a Hydro-electric power plant that serves to be the second largest after Masinga Hydro-electric power plant. The design storage capacity of Turkwel reservoir has been reducing over the years and the main reason attributed to this reduction is the sedimentation of loose aggregates of soil particles that are detached due to erosion and transported downstream by stream networks that drain into the Turkwel reservoir.

Environmentally friendliness of renewable energy, sustainability, and championship from international bodies such as IRENA and United Nations under the Sustainable Development Goals (SDGs) has led to the massive rise of development and utilization of renewable energy in the world. Global installed wind-generated capacity onshore and offshore has increased by a factor of almost 75 in the past two decades, jumping from 7.5GW in 1997 to 564GW by 2018.

Abstract With the gradual increase in the demand for power because of increased economic productivity and population, coupled with the aim of attaining the Sustainable Development Goals, there has been an increase in the uptake of renewable energy resources like solar power. This project assessed the suitability of setting up large-scale Photovoltaic (PV) solar power plants in Laikipia County. PV solar plants that generate more than 500 kilowatts (kW) are considered to be largescale photovoltaic systems.
