Gatorade Plant to Reduce Emissions by 20%

13 Jul 2017


The Gatorade Company, Inc., a division of PepsiCo, completed construction of  combined heat and power (CHP) system at its processing plant in Mountain Top, PA in November 2016. The objective of this project was to reduce cost and to help achieve their goal to reduce greenhouse gas emissions 20%
by the year 2030.

This project was developed internally by PepsiCo engineers with financial support from their electric utility company. The gas installation was supported by the UGI Engineering Team.

The CHP plant consists of one 2MW motor designed to recover hot water at 150F from its jackets and aftercooler, and to generate saturated steam at 100 psig from its exhaust gases. The recovered hot water is used to pre-heat process water prior to pasteurization and the steam is injected into general plant steam grid.

This project has an expected electric efficiency of 37%, and a thermal efficiency of 48%, which is reasonable for a project of this size. The overall efficiency of 85% is significantly higher than other conventional power generator units.

Waste heat recovered

As most successful CHP systems, this equipment is supported by two boilers which also generate steam at 100 psig. As in most CHP projects, these boilers were previously responsible for the whole steam and hot water generation, and now their utilization is being reduced by the CHP thermal production. In any case, a complementary thermal redundancy is strongly recommended to respond to quick changes in demand and to shave peak load, as CHP generators perform better on a base load regime.

The UGI EE&C rebate

As of January, 2017 UGI Gas began offering a CHP rebate of $750 per kW on equipment installed; not to exceed 50% of project cost or a maximum of $250,000. The rebate is available to current and new UGI Gas customers who take service under rate class DS or LFD.

“This CHP installation enables us to not only save money on
our annual operating costs, but also provides an environmental
benefit as well. With a simple payback of 5 years, this project
was an excellent opportunity to partner with UGI.”
– Andy Lempera from PepsiCo

Financial analysis

This system generates 14.8 GWh and 74,000 MMBTU of electric and thermal energy annually, which generates savings over $1.2 million. The total investment for this project was close to $3.5 million, which was supported with a $500,000 incentive from the customer’s electric utility company. The additional operational cost, which includes fuel and maintenance, is estimated at $160,000. Overall, the project has a simple payback of 5.08 years.
