GENERAL MILLS DIGESTER
In late 2014, a ReNew Petra affiliate teamed with CHA to assist the General Mills Yoplait Plant in Murfreesboro, Tennessee in self-developing a $14-million, 1.6MW digester gas to energy project. The team installed a state-of-the-art gas digester that processes plant waste product, blower/flare coordination, gas compression and cleanup, and a state-of-the-art Power Generation and Heat Facility. The project also included:
- A 1.6MW engine-generator
- Hot Water Heat Recovery System
- Generator housing
- Related piping and controls
- Utility interconnect
Our team negotiated the PPA / Net Metering agreement with Tennessee Valley Authority, and was responsible for FERC licensing and registration of landfill methane destruction under the TVA Renewable Initiative. The project was implemented on a fast-track, design-build basis.
A ReNew Petra affiliate provided a wastewater treatment plan for Monogram Foods in Martinsville, Virginia, along with a single 750kW packaged Caterpillar Engine Generator facility, complete with all related gas compression, clean-up, piping, valves and electrical. Production occurs 24/7/365, with electrical demand and natural gas use (including the wastewater treatment plant) projected to be greater than 600kW and 2.75 MBtu/hr respectively. The addition of the generator lowers OPEX by nearly $420,000 per year due to avoided electrical and natural gas costs.
Our team also provides ongoing operations and maintenance support for the facility. We conduct ongoing predictive, preventative, usual and customary maintenance for the biogas fired CAT CG132-8 Engine-Generator, as well as provide emergency support services. This includes continual evaluation of maintenance data and assess financial costs and benefits to Monogram Foods.
NORTH CAROLINA PAPER COMPANY
A ReNew Petra affiliate provided infrastructure engineering management and demand management services for a refurbished Brownfield pulp and paper operation. The project involved 15 MW of generation capacity provided by four turbines, with six active coal-fired boilers and six specialty production lines. Our team supported efforts to renegotiate energy contracts and implemented infrastructure improvements that yielded 35% savings on total energy costs.
