Well I don't know if milk production and vegitables need any plant which would require such thing. However, suppose electricity cost accounts for, say 10% of something which weighs 2% in CPI basket. The net impact will be 0.2% on inflation (called energy effect). However, if you see the headline hasn't steepened as much as food which includes raw food supplies and contain minimal energy effect. And since food markets are mostly geographically constained, thus they fall under the preview of provincial government like in Sindh and Punjab, the provincial government controls the prices of food, not the federal government.
