A negawatt market would allow "demand side resources" to participate in wholesale energy markets. These markets are commonly referred to as a demand response. Demand response can be defined as "enrolling large users of energy in programs to lower their usage in return for compensation, which helps take pressure off the grid" This market would help take pressure off the grid because electricity could "be treated as a commodity just like copper or sowbellies," and therefore traded to areas that need it more than others.{ As any commodity, negawatts would have to be "tradable across time and space" to be an effective market. Being able to trade negawatts across time and space would allow for an international trading system. To create a market for negawatts, energy companies will need to put more focus toward energy efficiency. This shift in focus would require a new "business structure that will thrive in the 'negawatt market'", which has not yet been developed. Market possibilities are being implemented internationally, implying that one day an official negawatt market will become a reality.
