Install capacitors with automatic operation to keep the power factor near unity.

Provide proper insulation on steam pipes and fittings.

Ensure to load transformer at its best efficiency point. Avoid unnecessary running of under loaded transformer.

Ensure proper loading on electrical motor. If load is below 50%, replace it with the properly sized motor.

Avoid frequent rewinding, as it reduces the motor efficiency it is better to replace the old motor with new energy efficient motor.
