304 Commonwealth Energy System Synergy will also be achieved with COM/Energy's other new business endeavor: an energy management services business unit. As opportunities for applying cogeneration technologies are explored, it is likely that related opportunities for energy efficiency improvements will be uncovered. These opportunities can then be capitalized upon by the energy management services subsidiary. Similarly, the energy management services subsidiary will likely uncover situations where potential customers could benefit from cogeneration technology and pass such information along to the energy supply services subsidiary. It is also possible that other synergies will arise between proposed sub sidiaries. An energy brokerage subsidiary could act as a fuel supplier to potential cogeneration customers by providing natural gas and oil and/or marketing excess electrical energy. Cogeneration plant operation and maintenance will also complement COM/Energy's experience at the Canal plant and steam facilities. The business structure for the energy supply systems subsidiary will entail acquisitions or joint ventures. Under the latter structure, the subsid iary could act as prime contractor and project manager with the partner generally supplying its technology.
