In Boone, North Carolina, Hollar & Greene Produce Co. faces a critical temperature control challenge for its cabbage shipments to Walmart, necessitating precise chilling at 36 degrees Fahrenheit. Deviations beyond 1 or 2 degrees can lead to the rejection of up to 1,000 boxes, according to Tony Greene, the company's fleet manager. Traditionally reliant on diesel fuel for refrigeration, the substantial electricity demand for maintaining optimal temperatures resulted in high operational costs.
The transition to an electric transport refrigeration unit (eTRU), facilitated by a collaborative pilot with Surry-Yadkin Electric Membership Corp., marks a significant shift. This initiative, aimed at beneficial electrification, has enabled the prominent cabbage shipper to achieve lower fuel expenditures and minimize emissions and noise pollution. The eTRU, positioned between the driver's cab and trailer, connects to the warehouse infrastructure, offering substantial annual savings in fuel and maintenance.
The success of this pilot in Mount Airy has prompted North Carolina's Electric Cooperatives to consider a statewide expansion, developing a guide for integrating this technology across various sectors. James Musilek, vice president of innovation and business development, emphasized the goal of assisting members in achieving reduced emissions and operational costs. This initiative aligns with broader efforts to address transportation-related emissions, which constitute a significant portion of North Carolina's greenhouse gas output.
Further, the state's electric cooperatives are exploring electrification in agriculture and industry, including a smart farm project by Four County EMC and James Sprunt Community College. This venture into agricultural hydroponics represents a forward-thinking approach to supporting North Carolina's agricultural sector through innovative technology.
