generators don't have a power output in hel mod? https://photos.app.goo.gl/HDv2CnC6ennyb1JW6

I don't understand what I'm looking at in your screenshot. I've never used Helmod

the mod previously would show a power figure on the output side of the steam turbine column. ill ask in the help mod side as well

https://photos.app.goo.gl/uSKrmWfyN8SBTemM6 before and after photos. I found an older helmod production cell, this is the result of remaking it.

I found the problem
Solarthermal energy mod use a not conventionnal usage_priority for electric_energy_source_prototype property of generator turbine
normaly generator use "secondary-output" not "primary-output" @see https://wiki.factorio.com/Types/ElectricUsagePriority#secondary
