Coal is becoming a less competitive energy source with cheaper options like natural gas and other renewables on the market, Vistra Energy CEO Curtis Morgan told CNBC's on Monday.
"I don't believe [coal] is going to have a renaissance," Morgan said in an exclusive "Mad Money" interview. "I think it's on its way out."
"As much as I believe it is going to be part of the energy infrastructure around power, I believe that other sources are now catching up with coal in terms of the overall costs," Morgan said.
In February, Vistra Energy, parent company to TXU Energy and Luminant, shut down 4,200 megawatts of coal-fire capacity "because they just couldn't make it in today's world," Morgan said.
Looking to the future, the company has invested in a 180-megawatt solar plant in Texas, the CEO said, adding that Vistra's leadership is continuing to look into other renewables like battery power.
"Batteries just open up a very different world and they're becoming more and more cost-effective," Morgan told Cramer. "When you combine batteries with the intermittent nature of renewables, you can create a more stable electric product."
Vistra Energy has a market cap of $9.4 billion and serves nearly 3 million retail customers. Vistra shares were trading just over $21 Monday, compared with about $16 a year ago.
