A rural utility needed to reduce peak power consumption. During the summer months (June through September), Northeast Nebraska Public Power District (NNPPD) is faced with a particular challenge from its irrigation customers. They needed to reduce peak power consumption.
Though only numbering 550 of the 8,500 customers, these big system irrigators drive over 50% of the District’s total power consumption during the summer months.
NE Nebraska Power needed to shed load during certain times when the cost of purchased power would be at higher rates.
Since the irrigators controlled their own irrigation pivots, NE Nebraska Power needed a mechanism to allow them to reduce the load from these big irrigator customers during those days and times when the cost of purchased power was the highest.
