Paradox Interactive has opened a Hearts of Iron IV beta for a redesigned energy system. The test adds a country power pool and ties industrial output to the balance between electricity supply and production demand. Paradox says the feature is still under evaluation, so participation is a test rather than confirmation that the system will reach the main game unchanged.
Factories now depend on available power
Under the proposed system, production lines consume energy while civilian factories, military factories, dockyards and power plants contribute supply. The ratio between demand and available power determines an industrial buff or penalty. Production screens also break consumption down across land, air and naval equipment, making energy use visible rather than leaving it as a background modifier.
Power plants occupy state building slots and can be upgraded to three levels. Their output varies with local terrain, oil and dams. Coal is consumed only when required, while oil-producing states improve power-plant output without turning oil into a general industrial fuel. Paradox’s stated division keeps oil focused on military fuel and coal on industry.
Surplus capacity has a purpose
The beta rewards countries that produce more electricity than they immediately need. Spare capacity provides a bonus, and its threshold scales with the size of a country’s factory base. A new research path improves generation; the example shown by Paradox includes Hydrogen-Cooled Generators, which raises total energy production by 10%.
Two military industrial organization policies offer another trade-off. Electrified Assembly lowers production energy costs, while Power Rationing raises power demand in exchange for other production benefits. Power plants are also more vulnerable to strategic bombing, although sufficient reserve capacity can improve repair speed.
What players should expect from the test
The open beta includes world setups for 1936 and 1939, AI logic for constructing power plants, revised industrial-focus rewards and interface alerts for shortages. It does not include translations or finished art for every new icon. Paradox is asking players to report balance concerns and share accounts of their campaigns.
The practical effect is a new planning constraint. Large economies must account for the electricity cost of expanding production, while smaller countries may need to specialize instead of building broadly. Because this is beta software, exact values and mechanics can change before any wider release.
