This invention relates generally to methods, systems, and devices for mitigating risk in distributed energy assets.
Energy generating or energy efficiency equipment can provide substantial utility savings as well as environmental benefits. Often though, purchasing this equipment may be prohibitively expensive and it might take a long time to recoup the initial investment through savings derived from the system. Assets such as equipment loans, equipment leases, power purchase agreements, shared savings agreements, and energy service agreements have been created in order to reduce or remove upfront cost allowing a much larger user base.
In order for investors, developers, lenders, or installers to gauge the risk involved in these assets, factors such as credit rating of the user, utility rates, expected production, projected energy and economic savings, etc. are often examined before creating the asset or installing equipment. Assets such as these may have long economic lives and thus risk factors could change significantly during the life of the asset. These static determinations of risk therefore poorly represent risk after creation of the asset and adoption of equipment. Also, users of electricity may have different preferences with regard to fixed vs. variable payments for future usage.
A key risk in distributed energy assets is tariff risk. Adopters of equipment under fixed-rate leases or PPAs bare all the risk that the tariffs will rise at a lower rate than projected. This may be neither trivial nor a risk many prospective adopters would prefer to take on if they had an option. Moreover, some potential adopters will forego the investment in this system because of their unwillingness take on this economic risk.
It would be desirable to provide alternative and improved methods, systems, and devices for mitigating risk in distributed energy assets. At least some of these objectives will be met by the invention described herein below.
In one aspect, the present application discloses methods, systems, and devices for mitigating risk in distributed energy assets. In one embodiment a computerized method for mitigating risk in distributed energy assets is disclosed, comprising purchasing, using a processor, a bundle of distributed energy assets, wherein the distributed energy assets comprise agreements by end-users of distributed energy resources to purchase energy at variable rates which are tied to future utility rates or an index; and swapping with one or more off-takers, using the processor, a variable stream of cash flows based on a variable future utility rate and energy quantity for the off-taker for a fixed stream of cash flows based on a fixed rate and the energy quantity for the off-taker. Variable rates of the distributed energy assets may be discounted by a percentage or a fixed value from the future utility rates for the end-users. The variable rates of the distributed energy assets may also be tied to average national utility rates, average regional utility rates, commodity prices, home prices, or inflation.
In another embodiment a computerized method for mitigating risk in distributed energy assets is disclosed, comprising purchasing, using a processor, a bundle of distributed energy assets comprising agreements by end-users of distributed energy resources to purchase energy at fixed rates; and swapping with one or more off-takers, using the processor, a variable stream of cash flows based on a variable future utility rate and energy quantity for the off-taker for a fixed stream of cash flows based on a fixed rate and the energy quantity for the off-taker.
In various embodiments, the distributed energy resources comprises photovoltaic, solar thermal, wind energy, heating, cooling, HVAC, insulation, water processing, or water purifying equipment.
In another aspect, the methods further comprise identifying the bundle of distributed energy assets, receiving energy-related data associated with the bundle of distributed energy assets, calculating future payments from the bundle of distributed energy assets based on the energy-related data associated with the bundle of distributed energy assets, identifying the off-taker, receiving energy-related data associated with the off-taker, calculating future cash flows to the off-taker based on the energy-related data associated with the bundle of distributed energy assets, and matching the bundle of distributed energy assets with the off-taker based on the calculated future payments from the bundle of distributed energy assets and the calculated future cash flows to the off-taker. Received energy-related data associated with the bundle of distributed energy assets or received energy-related data associated with the off-taker may comprise data relating to changes to regulations, taxes, government incentives, utility incentives, usage data, equipment performance data, utility pricing, macroeconomic data, weather, or technology data. Calculating future payments from the bundle of distributed energy assets may comprise calculating estimated future utility rates or energy quantities for the bundle of distributed energy assets. Calculating future cash flows to the off-taker may comprise calculating estimated future utility rates or energy quantities for the off-taker.
This, and further aspects of the present embodiments are set forth herein.
Present embodiments have other advantages and features which will be more readily apparent from the following detailed description and the appended claims, when taken in conjunction with the accompanying drawings, in which:
While the invention has been disclosed with reference to certain embodiments, it will be understood by those skilled in the art that various changes may be made and equivalents may be substituted without departing from the scope of the invention. In addition, many modifications may be made to adapt to a particular situation or material to the teachings of the invention without departing from its scope.
Throughout the specification and claims, the following terms take the meanings explicitly associated herein unless the context clearly dictates otherwise. The meaning of “a”, “an”, and “the” include plural references. The meaning of “in” includes “in” and “on.” Referring to the drawings, like numbers indicate like parts throughout the views. Additionally, a reference to the singular includes a reference to the plural unless otherwise stated or inconsistent with the disclosure herein.
The word “exemplary” is used herein to mean “serving as an example, instance, or illustration.” Any implementation described herein as “exemplary” is not necessarily to be construed as advantageous over other implementations.
The present disclosure describes methods, systems, and devices for mitigating risk in distributed energy assets comprising agreements by end-users of distributed energy resources to purchase energy. The term “energy” as referred to herein is defined to include electricity, natural gas, water, heating oil, and the like. The term “distributed energy resources” as referred to herein is defined to include energy or water related equipment such as energy generating systems (photovoltaic, solar hot water, solar thermal, wind energy, geothermal energy, hydroelectric, combined heat and power), distributed energy equipment, energy or water efficient equipment (appliances, lighting, HVAC, insulation, smart devices, sensors), heating/cooling systems (heating oil, gas, geothermal heat pumps), energy storage systems (battery storage, fuel cell systems, thermal storage, fly wheels, electric vehicles), systems for cleaning, processing, storing, or purifying water, energy efficient vehicles (electric, hybrid, fuel cell, etc.), and/or software that allocates/optimizes generation or usage of the above systems. In an embodiment, distributed energy resources may comprise demand-side management programs such as demand response and continuous commissioning.
Distributed energy resources may provide substantial energy or utility savings to residential, commercial, industrial, agricultural, governmental, educational, nonprofit, or any other user of energy or water. Often though, the initial investment to adopt such equipment can be quite large. Distributed energy assets such as equipment leases, equipment loans, power purchase agreements, shared savings agreements, energy service agreements, or the like, allow adoption of such equipment with reduced upfront cost to end-users of the distributed energy resources.
In an embodiment, distributed energy assets may comprise agreements by end-users 102a-n to purchase energy at fixed rates projected to be less than estimated future utility rates for the end-users 102a-n. Data from various sources such as data relating to regulations, taxes, government incentives, utility incentives, usage data, equipment performance data, utility pricing, macroeconomic data, weather, or technology data may be used to calculate estimated future utility rates.
As future changes in energy rates may be derived from tariff and pricing decisions of public utility commissions and utilities, technological developments, macroeconomic forces such as recession, events such as closing of power plants, developments of energy sources/distribution, or commodity prices, it is possible that actual future electricity rates/tariffs differ from the projections. Some potential end-users 102a-n may forego the investment in this system because of the uncertainty resulting from the economic risk they are taking on. In an alternative embodiment, developer 101 provides end-users 102a-n with a savings guarantee wherein end-users 102a-n agree to purchase energy at variable rates which are tied to future utility rates or an index. In an embodiment, the variable rates of the distributed energy assets are discounted by a percentage from the future utility rates for the end-users. For example, the end-user 102a-n may agree to purchase energy at a five percent discount from future utility rates. Alternatively, variable rates of the distributed energy assets may discounted by a percentage from the total utility bill. Variable discounts from total bills may consider changes to net metering, energy demand or capacity charges, and/or surcharges/penalties/fees or discounts for customers who deploy distributed resources. In another embodiment, the variable rates of the distributed energy assets are discounted by a fixed value from the future utility rates for the end-users 102a-n. For example, end-users may agree to purchase energy at a reduced rate. Assets may guarantee a fixed discount per month from the total end-user utility bill. Fixed discounts from total bills may consider changes to net metering, energy demand or capacity charges, or surcharges/penalties/fees or discounts for customers who deploy distributed resources. For example, the energy-related asset may guarantee a saving of $10 month. Additionally or alternatively, variable rates may be tied to average national utility rates, average regional utility rates, commodity prices, home prices, or inflation. While the term “discount” is used, it is also contemplated that the variable rates may be equal to or greater than future utility rates or indices. The variable rates will thus increase the number of potential end-users 102a-n as well as reduce the risk of default since the distributed energy assets will always be beneficial to the end-users 102a-n.
Hedger 205 receives a variable stream of cash flows 204 from the bundle of distributed energy assets 202 tied to variable future end-user utility rates or an index. As described above, the variable payments 204 from the bundle of distributed energy assets 202 may be based on a variable future utility rate, a discount, and an energy quantity for the end-users.
Hedger 205 swaps with one or more off-takers 206 a variable stream of cash flows 207 based on a variable future utility rate and energy quantity for the off-taker 206 for a fixed stream of cash flows 208 based on a fixed rate and the energy quantity for the off-taker 206. Off-taker 206 could be anyone seeking long-term rate stability such as a commercial or industrial entity or a speculator betting on future electricity rates. Payments 204 are used to service forward contracts hedger 205 writes with the off-taker 206 thus effectively swapping the variable stream cash flows 204 from the bundle of distributed energy assets with the variable stream of cash flows 207 to the off-taker 206.
End-users and off-taker 206 may be in different geographic regions having different utility rates. Additionally, end-users and off-taker 206 may be in different sectors such as residential, commercial, industrial, or agricultural with differing tariffs. Therefore the variable stream of cash flows 204 from the bundle of distributed energy assets 202 may differ from the variable stream of cash flows 207 to the off-taker 206 and thus hedger 205 bares the basis risk. In an embodiment, the hedger 205 matches the bundle of distributed energy assets 202 with potential off-takers 206 based on predicted cash flows in order to minimize the basis risk. The variable stream of cash flows 204 from the bundle of distributed energy assets 202 may also be tied to the variable stream of cash flows 207 to the off-taker 206.
Hedger 405 swaps with one or more off-takers 406 a variable stream of cash flows 407 based on a variable future utility rate and energy quantity for the off-taker 406 for a fixed stream of cash flows 408 based on a fixed rate, and the energy quantity for the off-taker 406. Payments 404 are used to service forward contracts hedger 405 writes with the off-taker 406 thus effectively swapping the fixed stream cash flows 404 from the bundle of distributed energy assets with the variable stream of cash flows 407 to the off-taker 406. Hedger 405 may match the bundle of distributed energy assets 402 with potential off-takers 406 based on predicted cash flows in order to minimize the basis risk.
In an alternative embodiment, Hedger may purchase a bundle of distributed energy assets comprising agreements by end-users of distributed energy resources to purchase energy at fixed rates projected to be less than estimated future utility rates for the end-users; wherein Hedger swaps with one or more off-takers a first variable stream of cash flows based on a variable future utility rate and energy quantity for the off-taker for a second variable stream of cash flows based on a variable rate and the energy quantity for the off-taker.
While embodiments have been described using fixed-for-variable swaps, other embodiments may include index-linked bonds or other investment vehicles such as strips, derivatives, secondary offerings, tiering of cash flows, etc.
In any of the above systems it is desirable to match distributed energy assets with off-takers based on predicted cash flows in order to minimize basis risk.
At step 602, energy-related data associated with the asset is received. Received data may be any data relevant to the distributed energy assets such as data relating to laws, regulations, taxes, government incentives, utility incentives, usage data, equipment performance, utility pricing, weather, macroeconomic data, and/or technology data.
At step 603, estimated future payments from the distributed energy assets are calculated based on the received data. In an embodiment, calculating estimated future payments from the distributed energy assets comprises calculating estimated future utility rates for the distributed energy assets. Calculating future payments may also comprise calculating an estimated future energy quantity for the distributed energy assets such as energy consumption or energy production by the equipment.
At step 604, one or more off-takers are identified. At step 605, energy-related data associated with the off-taker is received. Received data may be any data relevant to the off-taker such as data relating to laws, regulations, taxes, government incentives, utility incentives, usage data, equipment performance, utility pricing, weather, macroeconomic data, and/or technology data.
At step 606, estimated future cash flows to the off-taker are calculated based on the received data. In an embodiment, calculating estimated future cash flows to the off-taker assets comprises calculating estimated future utility rates for the off-taker. Calculating future cash flows to the off-taker may also comprise calculating an estimated future energy quantity for the off-taker such as energy consumption.
At step 607, the estimated future payments from the distributed energy assets are compared to the estimated future cash flows to the off-taker. If the estimated future payments from the distributed energy assets are less than the estimated future cash flows to the off-taker then step 604 is repeated and another off-taker is identified. If the estimated future payments from the distributed energy assets are greater than or equal to the estimated future cash flows to the off-taker then the distributed energy assets and the off-taker are matched at step 608. The processes in
At step 703, estimated future cash flows to the off-taker are calculated based on the received data. In an embodiment, calculating estimated future cash flows to the off-taker assets comprises calculating estimated future utility rates for the off-taker. Calculating future cash flows to the off-taker may also comprise calculating an estimated future energy quantity for the off-taker such as energy consumption.
At step 704, energy related assets are identified. In one embodiment a bundle of energy related assets are identified. Alternatively a single energy related asset may be identified.
At step 705, energy-related data associated with the asset is received. Received data may be any data relevant to the distributed energy assets such as data relating to laws, regulations, taxes, government incentives, utility incentives, usage data, equipment performance, utility pricing, weather, macroeconomic data, and/or technology data.
At step 706, estimated future payments from the distributed energy assets are calculated based on the received data. In an embodiment, calculating estimated future payments from the distributed energy assets comprises calculating estimated future utility rates for the distributed energy assets. Calculating future payments may also comprise calculating an estimated future energy quantity for the distributed energy assets such as energy consumption or energy production by the equipment.
At step 707, the estimated future payments from the distributed energy assets are compared to the estimated future cash flows to the off-taker. If the estimated future payments from the distributed energy assets are less than the estimated future cash flows to the off-taker then step 704 is repeated and another off-taker is identified. If the estimated future payments from the distributed energy assets are greater than or equal to the estimated future cash flows to the off-taker then the distributed energy assets and the off-taker are matched at step 708. The processes in
In any of the above systems or methods it may be desirable to calculate estimated future retail utility rates for a utility customer.
The system may repeat any of the above steps multiple times continuously or periodically in order to dynamically adjust the estimated future utility rate due to changes in relevant factors. In an embodiment, additional energy-related data representing additional factors not used in calculating the previously calculated estimated future utility rate or changes to factors used in calculating the previously calculated estimated future utility rate are received. The estimated future utility rate may then be recalculated based on the received additional energy-related data.
In one embodiment, calculating an estimated future retail utility rate comprises receiving energy-related data associated with a first geographic segment, and calculating an estimated future utility rate for a second geographic segment based on the received data associated with the first geographic region. In another embodiment, calculating an estimated future utility rate comprises predicting changes to taxes, statutes, or regulations.
