Are the natural gas power plants in LA outdated in technology?

Question

If it's outdated, why won't they replace them with the most efficient ones?

Answer 1

As I understand it, they are 30 years old and grotesquely inefficient.  They are not updated as the city does not have the money to do so.

Answer 2

All power stations have an economic life of 30years.  All along its operational life, the owners put in state-of-the-art systems and equipment in order to maintain and improve its ROI.  At the end of 30years, these plants are decommissioned and new power stations are built.
