KPMG has released a report that with the rise of renewable energy, the capacity utilization rate of many coal-fired power plants in India will fall to 35-40%
by 2022.
KPMG forecasts that the average capacity utilization rate of coal-fired power plants today is around 51%, and some plants may have to close or shut down their piles
seasonally.
"According to an analysis by KPMG in India, even a scenario of using 130 GW of renewable energy by 2022 instead of the planned 175 GW could result in plant load ratios (PLFs) falling to 35% to 40%
for many coal-fired power plants.
"
"The increased penetration of renewables in the power system requires flexible operation of conventional power plants
," the report said.
”
The flexible operation of traditional coal-fired power plants has been somewhat resisted
by incumbent operators.
According to KPMG, the minimum technical limit can often be reduced to 40%
under Indian conditions if there is a choice between plant closure and operation.
"However, this will require retrofitting of plant equipment and instrumentation, as well as extensive changes to operating methods and human capabilities to safely manage cyclic operations, a process with frequent start-stop functions, and lifting and lowering the plant through technical, operational and commercial modifications, the latter option is certainly preferable", KPMG mentioned
in the study.
In addition, the rise of energy storage technology is also increasing the flexibility of coal-fired power plants, resulting in lower technical requirements, reduced start-up time, and higher heating rates
.
To achieve utilization levels below 40% (for example, in Germany, plants drop to 20% to 25%), coal quality needs to be improved and controlled, and large quantities of coal
are also required.
