Narrative:

There is a new power plant 1.5 miles ssw of jyo. The plant has just opened. The power plant is 0.25 miles from the centerline extended of runway 17/35. The power plant is 1.0 miles from the departure end of runway 17.left pattern for runway 17. Pattern height 1;200 ft MSL (800 ft AGL) climb out from runway 17. Standard left turn to crosswind is at 900 ft MSL (300 ft below pattern). This turn is at 500 ft AGL.the turn to left crosswind departing runway 17 in a C172 takes the plane directly over the power plant (500 ft AGL) and through the thermal plume of the cooling system. It's a very bumpy ride directly through the thermal plume above the power plant.today had to make left turn to crosswind at 800 ft MSL (400 ft AGL) or wait and turn left crosswind at 1;000 ft MSL (600 ft AGL) thus turning left crosswind either before or after the power plant.
