According to Kenya Power, sudden fluctuations in wind and solar generation can affect the frequency and voltage of electricity supplied through the national grid, forcing the utility to dispatch additional generation sources to maintain system stability. Kenya Power Managing Director and Chief Executive Officer Dr Eng Joseph Siror said the country needed to carefully consider the costs associated with integrating additional intermittent renewable energy into the grid. He said the intermittent nature of wind and solar meant Kenya Power was sometimes forced to dispatch and pay for additional generators even when renewable sources were producing electricity. Siror argued that the cost of variable renewable energy should therefore be assessed alongside the additional generation required to stabilise the grid. Kenya Leads Region in Variable Renewable EnergyKenya currently has the highest dependence on variable renewable energy among countries in the Eastern Africa Power Pool, according to Kenya Power.
