Abstract
In ensuring proper energy mix and reducing the number of emissions from traditional thermal plants for power generation, the Energy Commission of Ghana built the Solar Power Plant at Navrongo. This was to help cut down the cost of crude fuel imports and also play a part in mitigating global warming which results from the continuous emission of carbon dioxide (CO<sub>2</sub>) at the thermal power. Over the years the plant has been faced with inconsistent power generation. This research paper sought to investigate the power losses at the Navrongo Volta River Authority (VRA) Solar Power Plant and come out with measures to improve its efficiency. Power production downtime and power transmission losses were identified as the major constraints of the solar power plant. General evaluation and review of the grid design and transmission system of the plant were considered and a microgrid technology was proposed to eliminate generation downtime and power transmission losses. The output of the proposed microgrid system was predicted using R-studio statistical simulations, also the plant was optimised to ascertain the gains in power generation and the merits of this system were discussed. Finally, conclusions and recommendations where made to ensure energy security and economic competitiveness of the plant.

The Energy Commission of Ghana in ensuring proper energy mix and reducing the number of emissions from traditional thermal plants for power generation, built the Solar Power Plant at Navrongo. This was to aide Ghana cut down the cost of crude fuel imports and play a part in mitigating global warming which results from the continuous emission of carbon dioxide (CO2) at the thermal power generating stations in the country [1]
It has come to the notice of the management of the plant that there is inconsistent power generation from the plant, this is because the DC inverters are power sensitive, and they depend on the Navrongo-Pungu grid lines for power supply
Summary
The Energy Commission of Ghana in ensuring proper energy mix and reducing the number of emissions from traditional thermal plants for power generation, built the Solar Power Plant at Navrongo. This was to aide Ghana cut down the cost of crude fuel imports and play a part in mitigating global warming which results from the continuous emission of carbon dioxide (CO2) at the thermal power generating stations in the country [1]. The output power deficit stands at 1.1 MW in terms of installed capacity. This loss is significant in terms of power supply to the people of Ghana, and when translated into money is about GH¢ 9,367.74 (USD 1622.46) loss of income per day. This paper analyses the power generation process, performance indexes and ways of improving power efficiency at the solar plant
