He is completely right about allowing other entities to buy electricity and sell it to other entities than the government. When the government is the sole entity allowed to buy and sell electricity in a country, it can have major drawbacks.
One of the primary drawbacks of this is the absence of competition in the electricity market. Without competition, there is less incentive for the government to keep prices low and improve the quality of service. Consumers don't have choices in terms of electricity providers, leading to inefficiencies and higher costs. There is less incentive for the government to innovate and improve its electricity services when there is no competition. This leads to outdated infrastructure and less efficient use of resources. Government monopolies are often slower to adopt new technologies than competitive providers. This is because they are not under the same pressure to innovate. Pakistan energy transmission systems are the finest examples of this, they create an insane amount of losses.
Also, his point about utilizing local coal is 100% correct. Kindly visit this thread for more information on the topic:
