As the country’s energy landscape shifts towards renewable sources, the National Grid faces the challenge of integrating these new energy sources into its existing infrastructure and operations while continuing to meet the increasing electricity demand.
One of the primary challenges of integrating renewable energy sources into the grid is their intermittency and variability. Unlike conventional power plants that generate electricity continuously, renewable energy sources such as solar and wind depend on weather conditions and can produce fluctuating power levels. This unpredictability presents difficulties for the National Grid in maintaining a stable energy supply. It requires implementing measures to manage and store excess energy during periods of high generation.
In addition to the challenges posed by intermittency, integrating renewable energy sources requires significant updates and expansions to the existing distribution and transmission infrastructure. Renewable energy projects are often located in remote areas, which necessitates the construction of new transmission lines to connect these projects to the grid.
