A computing device 112 for use with a power system 100 includes a communication interface (230, fig.2) that is configured to receive energy data from at least one utility 106. The energy data includes at least one of at least one quantity of energy and at least one energy price. A processor (214, fig.2) is programmed to generate at least one offer to purchase energy based on the energy data received. An operator can decide whether to sell energy to the utility 106by responding to the offer to purchase energy. For example, a source of renewable energy 102, 104, such as a lithium battery or solar power, may be operated by an individual who can use the invention to sell power to a grid or utility 106 at a competitive rate. A power system using such a computing device 112, and a method for the sale and purchase of energy are also disclosed.
