Severe weather conditions triggered by climate change can adversely affect the operation of power plants.

Heavy rainfall, heatwaves and lightning can disrupt electricity transmission and distribution networks and cause power outages.

World - Bank - Report - Shocks - Climate

A 2019 World Bank report showed natural shocks and climate change caused 44% of power outages in the US between 2000 and 2017 and 37% of outages in Europe between 2010 and 2017.

This cost electricity utilities, consumers and governments billions of dollars per year.

Cases - Indonesia

Similar cases also happen in Indonesia.

Our study found disruptive weather and climate change disrupt the electricity supply chain, including electricity generation, transmission and distribution, affecting Indonesia's state-owned electricity company (PLN) and its consumers.

Field - Work - February - March - Study

Based on extensive field work in February and March 2018, the study involved interviews and focus group discussion supplemented by published reports and PLN's internal reports.

At least three categories of severe weather events may disrupt the operation of power plants in Indonesia.

Heavy - Wind - Rainfall - Threats - Power

Heavy wind and rainfall are by far the most significant threats to the power distribution networks.

In the Java-Bali region alone, these events accounted for more than 95% of weather-related power outages during 2014–2015.

Winds - Trees - Billboards - Power - Distribution

Strong winds knocked down trees and billboards onto power distribution lines.

Heavy rainfall also led to widespread power cuts as soaked, heavy tree branches touched distribution wires.

Heavy - Rainfall - Power - Plants - Transmission

Heavy rainfall also made coastal power plants and transmission substations more vulnerable to floods. This could lead to emergency power shutdowns.

A notable example is a severe flood on the northern coast of Jakarta in January 2013 that forced the gas-fueled Muara Karang power plant to shut down for 12 days.

Units - Distribution - Substations - Central - Jakarta

Furthermore, more than 500 units of inundated distribution substations in the Central Jakarta region were turned off for safety reasons. The incident cost the state US$15 million.

Coal and gas power plants are also at risk from heavy rainfall and rising seawater temperature. Excessive river flow due to heavy rainfall...
