What do you call a power plant that generates both electricity and heat?

There are thermal power stations that generate both electricity and heat which is used for heating residential houses close to it.

There are quite a few such power plants in, among others, Russia, Ukraine (both links in Russian), and (to a lesser extent) Germany:

• In Russian, Ukrainian, and Belorussian, it is called теплоэлектроцентраль, literally "heat and electricity central".
• The German word is Heizkraftwerk, literally "heating power plant" (a power plant that heats).

What do you call such power plant in English?

What I could find on my own

In a Wikipedia article on district heating I found the term combined heat and power plant. What I find a little confusing is that it links to an article about cogeneration which, at a first glance, looks like some modern, fancy innovation. This is definitely not true for such power plants in the ex-USSR because they have been there for decades.

According to Google NGram this term is used relatively rarely:

The process is called cogeneration.

The plants are called CHP (Combined heat and power ) plants.

From Wikipedia:

Combined heat and power (CHP) plants recover otherwise wasted thermal energy for heating. This is also called combined heat and power district heating. Small CHP plants are an example of decentralized energy. ... The resulting low-temperature waste heat is then used for water or space heating.
