The invention is an optimization method comprising of: (a) uniform and efficient model and associated methods for computing the energy and emission impacts of each of a range of technological and commercial options, and (b) an integrated and efficient optimization model for trading off the technological and commercial options against each other to arrive at a financially optimal solution that complies with regulatory caps on emission. The energy and emission impact model handles options such as energy efficiency measures, renewable energy projects, carbon capture projects and carbon offsets. In addition to handling the direct emissions, the model handles indirect emissions resulting from purchased electricity or fuel. The integrated optimization model selects the solution that maximizes the total net present value of savings across the various technological and commercial options considering the location specific rates, prices and carbon caps as well as the different levels of investments within each project to choose from; this model performs this optimization over a series of time periods respecting capital budget and operational budget constraints. The quantities of carbon offsets that must be purchased or sold are also determined as part of this integrated model. |
