Method for receiving bids on an energy-savings and energy supply portfolio
A computer-implemented method for determining an optimal award schedule for satisfaction of energy efficiency and energy supply requirements for a portfolio of one or more buildings. A first auction is conducted so as to receive over a computer network, from one or more prospective efficiency suppliers, a plurality of first bids for the provision of energy efficiency, each such first bid specifying an amount of energy saved and a cost. A computer is used to determine a schedule of remaining portfolio energy supply requirements that would remain after the provision of energy efficiency from at least a plurality of the first bids. A second auction is then run so as to receive over the computer network, from one or more prospective energy suppliers, one or more second bids for a plurality of the remaining portfolio energy supply requirements, each such second bid specifying a cost. A computer is then used to determine the lowest cost combination of a first bid and a second bid that satisfies the portfolio energy requirement.
1. A computer-implemented method for determining an optimal award schedule for satisfaction of energy efficiency and energy supply requirements for a portfolio of one or more buildings, where the energy requirements of the portfolio are known, the method comprising:
a) receiving over a computer network, from one or more prospective efficiency suppliers, a plurality of first bids for the provision of energy efficiency measures that save energy use in the portfolio of buildings, each such first bid specifying an amount of energy saved and a cost for providing the energy efficiency measures;
b) determining by a computer a schedule of energy supply requirements in the form of one or more of electricity, oil and natural gas for the building portfolio that would remain after the provision of the energy efficiency measures from at least a plurality of the first bids;
c) receiving over the computer network, from one or more prospective suppliers of energy in the form of one or more of electricity, oil and natural gas, one or more second bids for a some or all of the remaining building portfolio energy supply requirements based on at least some of the first bids, each such second bid specifying a cost for providing the bid amount of energy in the form of one or more of electricity, oil and natural gas; and
d) determining by a computer a combination of a first bid and a second bid that together satisfies the portfolio energy requirement.
2. The method of claim 1 wherein there are a plurality of prospective efficiency suppliers that place first bids.
3. The method of claim 2 wherein the first bids comprise a quantity of avoided kilowatt hours (kWh).
4. The method of claim 3 wherein the first bids further comprise a cost per avoided kWh.
5. The method of claim 1 wherein determining by a computer a combination of a first bid and a second bid that satisfies the portfolio energy requirement comprises determining the costs of one or more combinations by calculating a first bid total cost plus a second bid total cost.
6. The method of claim 5 wherein determining by a computer a combination of a first bid and a second bid that satisfies the portfolio energy requirement further comprises determining the least expensive combination of a first bid and a second bid.
7. The method of claim 1 wherein receiving over a computer network, from one or more prospective efficiency suppliers, a plurality of first bids for the provision of energy efficiency measures comprises conducting a first auction.
8. The method of claim 7 wherein conducting a first auction comprises soliciting bids of an amount of energy efficiency accomplished by the energy efficiency measures at a bid cost, wherein the amount of energy efficiency bid on is variable.
9. The method of claim 8 wherein bidding on the variable amount of energy efficiency is constrained to bidding in blocks of avoided energy usage.
10. The method of claim 9 wherein the costs are bid per block of avoided energy usage.
11. The method of claim 8 wherein during the first auction the costs of bids are made available to all prospective bidders over the computer network, but the amount of energy efficiency measures bid on in the first bids is not made available to prospective bidders over the computer network.
12. The method of claim 8 wherein the amount of energy efficiency being bid on in the first auction is divided into units comprising avoided kilowatt hours, and the cost is bid on a per avoided kWh basis.
13. The method of claim 1 wherein determining by a computer a schedule of energy supply requirements in the form of one or more of electricity, oil and natural gas for the building portfolio that would remain after the provision of the energy efficiency measures from at least a plurality of the first bids comprises determining by a computer one or more possible lowest total cost combinations of energy efficiency measures first bid costs, plus the cost of remaining portfolio energy supply requirements at a plurality of different energy supply unit costs.
14. The method of claim 13 wherein receiving over the computer network, from one or more prospective suppliers of energy in the form of one or more of electricity, oil and natural gas, one or more second bids for a some or all of the remaining building portfolio energy supply requirements based on at least some of the first bids, comprises conducting a second auction.
15. The method of claim 14 wherein conducting a second auction comprises soliciting bids for energy supply amounts equal to the remaining building portfolio energy supply requirements for each of the one or more possible lowest total cost combinations of energy efficiency measures first bid costs plus the cost of remaining portfolio energy supply requirements at a plurality of different energy supply unit costs.
