Abstract: A control system comprises a utility power line; a first meter, a first generator, a second meter and a programmable logic controller. The utility power line provides power. The first meter is positioned to measure power provided by a utility company via the utility power line. The first generator generates additional power. The second meter is positioned to measure power generated by the first generator. The programmable logic controller is in communication with the first meter and the second meter to receive input information. The programmable logic controller is also in communication with the first generator to selectively control the first generator in response to the input information. The programmable logic controller controls the first generator to keep power provided by the utility company via the utility power line below a first amount at a first time.
