Polish Heat and Power

I was looking at International Energy Agency (IEA) stats on Electricity Generation. For most countries, an average of 90% of electricity is produced by electricity-only plants. But in Poland, 91% is produced by combined heat and power (CHP).

I thought this must be a mistake, but this excerpt from a googled site shows otherwise:

“Heat and hot water
The district heating sector in Poland comprises almost 400 individual networks, including the world’s largest district heating network in Warsaw. Of Poland’s urban population, 70% receive space-heat and 50% receive hot water from district heating systems. The sector is powered by a total of over 8,000 boilers, and delivers about 488 PJ (petajoules) of heat each year, at a peak rate of 45 GW. Out of this total heat production, approximately 170 PJ is produced within, and used by industrial enterprises.”

Wow! What does this mean? It means that instead of every house having it’s own water heater, there is a big chunk of Poland that gets it’s hot water from a central plant. Instead of everyone having their own heater, some people also get heat piped in from a central heating plant.
