Monsoon is essential to sustain the hydropower base in the state and the shortage in rainfall usually creates power crisis and increase in share of power purchase from outside the State. In general, variation in precipitation is likely to result proportional change in hydel power generation. The average temperature rise also causes increased evaporation from the water reservoirs as well as streams. The  ratio  of  hydro-thermal  mix  of electricity consumption of Kerala varies depending on the  hydro  storage  status  in  the  reservoirs; the water storage in the catchment area of hydel power plant depends on the water inflow, which in turn depends on the actual rainfall. The lower the rainfall means lower the share of hydel power, leading to costly imported thermal power purchase having higher carbon foot print.

A large portion of Kerala energy infrastructure like fuel ports, pipelines etc. are located in coastal areas and therefore sensitive to sea level rise. Changes in the frequency and severity of storms and other extreme events may also damage energy infrastructure, resulting in energy shortages that harm the economy and disrupt day-to-day life. Railways and marine transportation that move large amounts of oil and gas in the state are also vulnerable to climate change. Changes in precipitation could affect marine or water transportation of fuels by reducing the navigability of inland water bodies.  Oil and gas pipelines and storage facility and transportation can be designed to be more flexible to cope with impact of climate change.

Increasingly variable weather and potentially stronger storms would affect the integrity of Transmission and Distribution(T&D) lines and equipment in various ways. Strong winds can damage electric wires and other distribution components. Lighting affect the reliability of T&D lines. T&D infrastructure also suffer from increased risks of flooding, landslides, and other natural hazards. Increase in atmospheric temperature leads to increased chances of wildfires. Wildfires can directly damage transmission network and other electricity infrastructure; the risk also comes from smoke and particulate matter, which can ionize the air, create an electrical pathway away from transmission lines, and shut down the lines.
