Not Applicable.
The present invention relates generally to Renewable Energy Credit (REC) generation and allotment within and among entities which generate, buy, and sell RECs, and in particular to software that simplifies accounting of RECs in their various stages.
There is an increasing push to generate electricity from renewable energy resources. This is coming from all areas of our world, including from consumers demanding environmentally friendly companies and governments regulating environmentally friendly business. This movement has led to increased regulations regarding the electricity grid in sizeable, growing chunk of the world. These regulations require energy providers to produce minimum amounts of renewable energy as part of their total energy production.
To aid in regulation, production of renewable energy is tracked with many different units of measurement, one of which is called Renewable Energy Credits or Certificates (REC). RECs are allotted to renewable energy generation resources by Regional Renewable Energy Tracking Organizations. These Regional Renewable Energy Tracking Organizations then monitor compliance to ensure that energy providers are within their Renewable Portfolio Standards. If an energy provider has an excess of RECs, that energy provider can sell its RECs to another energy provider in need of REC. These transactions ensure an energy provider is always paying to produce renewable energy. Tracking of RECs currently involves multiple manual operations in a number of different systems, requiring that data be re-entered in each system. This process is time-consuming and error prone.

FIG. 1—Flow of Information through the invention
FIG. 2—input of Data into invention
FIG. 3A-3B—Allocation of RECs
FIG. 4A-4B—Allocation of Energy
FIG. 5A-5C—Attribution Policies
While this invention may be embodied in many different forms, there are described in detail herein specific preferred embodiments of the invention. This description is an exemplification of the principles of the invention and is not intended to limit the invention to the particular embodiments illustrated.
For the purposes of this disclosure, like reference numerals in the figures shall refer to like features unless otherwise indicated.
Embodiments of the present invention remove the complexity associated with the current state of tracking in the art. As a non-limiting example, users enter a minimal amount of data on a single display. Users are informed in real time about the status of their RECs. All created objects (rules, reports, transactions, future allotments) are available in a single tool. A Rule is defined to be a logic structure utilized to define unique allotments of generation to obligation via availability, user-specified Priority of Resources, and allocation policies.
As seen in
The system of method begins with the input of data into the software processes as seen in
The system can be made to receive the data via numerous methods, such as but not limited to having the user responsible for uploading this data “ready-to-use” in compliant XML format. Upload can be assisted by the system allowing a user to navigate to find an import file, granted that the import file is either on user's computer or a network drive which is accessible from user's computer. Before import, the user is able to view the file to ensure accuracy. Turning now to
Attempts to import a file 201 are recorded with the recorded information comprising the success 205 or failure 206/207 of the upload attempt, the timestamp of import, the file name, the information type, and the name of the user.
In some particular embodiments, in the course of such communications between devices the invention may further utilize encryption enabling software, such as but not necessarily limited to digital certificates, to secure access to the system and encrypt communications sent to and from the system. Using any number of methods known in the art, the invention may require and validate for the presence of specific encryption enabling software as a login credential. In preferred embodiments, such encryption enabling software is associated on a one-to-one basis with a particular user account. Login to the system of such embodiment would be denied unless the system validates, using any method known in the art, that a user's request to access the system includes the correctly corresponding login credentials comprising of username, password, and encryption enabling software, among others, associated with a particular predefined user account. Moreover, in other embodiments, encryption enabling software may be utilized to encrypt data communications within the invention or between the invention and other systems.
Moreover, communications between the inventive system/method and other destination systems may also be encrypted with encryption enabling software. Such encryption can be accomplished using any known means available in the art. As a non-limiting example, both the system of the present disclosure and a destination system can be set up with encryption enabling software, such as but not necessarily limited to digital certificates, to facilitate the encryption of communication sent from one system and the subsequent decryption of the information by the recipient system. Such pre-incorporation of encryption enabling software by both the sending system and recipient systems ensures that any intercepted communications cannot be read, thus raising the confidence level of transactions occurring within the system as a whole.
Successfully passing validation checks for format 206 and modeling 207, data is parsed into the system 204. Once saved to the system 204, all data inputted to the system can be viewed, modified, or allocated. The system also allows data to be viewed in different time formats such as but not necessarily limited to hourly or monthly formats. The system may facilitate the creation of system users with various levels of authorization, such that only users with assigned permissions can perform specific actions. In such an embodiment, the system may prevent all but specially authorized users from modifying inputted data.
Data which is brought into the system must fit into a pre-existing model. This model looks to verify that every incoming Obligation has been matched with Resources 111. This method of matching needs only be done once, though the data can be edited and updated at any time.
Every time a REC is sold or purchased in the system, the system tracks this with a transaction (Transaction). A number of Transaction types are supported as valid by the system, such Transaction types comprising sale to counterparty, purchase from a counterparty, assignment of RECs to a contract in a binding arrangement, assignment of RECs to a market, assignment of RECs to load, expiration of RECs, and inventory adjustment. On a REC Transaction, types of information which are supported as a valid input may comprise but are not limited to Resource, Vintage Month, REC quantity, Price, Comments, Currency, Broker Name, Broker Commission Type (percentage or fixed monetary amount), Broker Commission Dollar Amount, Comments, and Deal Date, among others. Varieties of REC transaction statuses which are supported may comprise but are not limited to Pending, Confirmed, Invoiced, Paid, Credits Transferred, and Transfer Acknowledged, among others.
Once balancing is called for 110 whether because of Attribution 113 or a user call for balancing data, the system finds the net energy balance 112 (Energy Balance) of the upload. The system associates each of the Resources with both the amount of energy generated by the Resource 103 (Gross Generation) and the amount of energy consumed by a Resource 104 (Service Station). The system then computes the Resource Net Generation as Gross Generation minus Station Service, where Gross Generation is greater than or equal to Station Service. The system may take other factors into account. Such factors may comprise but are not limited to imported energy 106 (Imports), the user's native need for energy 105 (Native Load), contractual sales of energy to a counterparty 107 (Bilateral Sales), and sales of energy to a market 108 (Market Sales). In one particular embodiment, the system quantifies the amount of energy available (Net Energy Available) by adding Imports 106 to Resource Net Generation. In order to calculate the total energy requirement (Net Obligation) of the upload 201, the system adds the Native Load 105, Negative Service Station 104, Bilateral Sales 107, and Market Sales 108. To quantify the system losses (Losses), the system then subtracts the Obligations from the Net Energy Available. The system then calculates how much energy was supplied by adding together Net Obligations and Losses. Finally, a user's net load (Net Load) is calculated as the Native Load 105 added to the Negative Station Services 104 and the Losses. The system performs all such calculations automatically at the moment attribution 113 is triggered, or at the moment the system balance 112 screen is opened by a user.
The system can also be configured to not allow user intervention to achieve such energy balance as described above. Such configuration can be then utilized to maintain the integrity of the balancing and therein the eventual attribution 113 of energy and RECs. In one particular embodiment, when the absolute value of calculated losses exceeds a user-defined percentage of Net Energy Available, the system may provide the user with an alert.
Upon completion of energy balancing 112, the system can attribute 113 energy and RECs 101 to obligations. This is done through a rule engine within the software system as seen in
Every Obligation is represented by a single rule. The system may also allow a rule to be created automatically when a particular Obligation is modeled 111 in the system. The system looks for every rule to be assigned to only one Obligation. The rule does so by allocating one or more Resources to this Obligation. Resources can be added or removed from a rule's Resource set.
In one particular embodiment, the system can allow a user to alter the order in which rules are executed by changing said rule's priority level (Rule Priority). Rules can be modified or effectively deactivated by setting the Rule Priority to a null value. In one particular embodiment, system can be configured to allow Rule Priorities to be distinguished with numbers.
A generating resource's energy and RECs 101 may be utilized in a symmetric or asymmetric manner to meet the Obligation, depending on how the resource attribution priorities are set up within the rule. Symmetric attribution means that energy and REC priorities are assigned equally (i.e. RECs follow energy). Asymmetric attribution means that energy and RECs are assigned separately.
if a rule is defined as symmetric, a single priority value is allowed for each resource in the rule definition. This priority value is used for both energy and REC allocation. If a rule is defined as asymmetric, independent priority values are allowed for both energy allocation and REC allocation. As a non-limiting example, users can create a rule using the asymmetric type, in which several resources supply energy but only one supplies REC to the Obligation.
Within a single rule, the assignment by the system of Resource Energy and/or RECs 101 is governed by allocation policies and resource priorities as assigned by the user. The system is arranged such that each resource within a rule is given a value which will dictate what order Resources are allotted to rules. As a non-limiting example, the system may allow users to set priorities by assigning whole numbers to indicate order of allocation, where such whole number corresponds to a priority (Resource Priority), If a user inputted a negative or non-whole number, the system would return an error. Each time that RECs are allocated to an Obligation, the systems records this as a transaction (Transaction). Turning now to
Turning now to
If the user has instead specified Supplied Percentage Attribution 503, then the Resources of applicable Resource Priority is attributed that percentage of the Obligation which correlates to said Resources' supplied/generated Energy in relation to other Resources of same Resource Priority 515. As a non-limiting example, if the Obligation is 20 and Resources A, B, and C all have the same Resource Priority and individual values of 10, 10, and 20, then A and B give half the amount of C as they have half the initial amount, resulting in final values of 5, 5, and 10 for Resource A, B, and C, respectively. Regardless of the allocation procedure, if the Resources in the Resource Priority do not have a combined value great enough to meet the Obligation, all Resources use the entirety of their value towards the Obligation for that Resource Priority 508/510. If the sum of all Resources in the Resource Priority group is less than the Obligation 509, then the system ensures that all Resources -will be exhausted for the selected Obligation 510 and the system will select the next Resource Priority group will be selected 305/405. This continues until either the Obligation has been met or all Resources have been exhausted 308/409.
A rule is executed when the specified Obligation is fully satisfied by the Resources associated with the rule 308409. If ever an energy Obligation cannot be satisfied due to insufficient Resource capacity or any other reason, the system will generate an error message 411 and the sequence halts. Together, rules comprise an execution sequence, as seen in
Altogether, the system's Attribution rule engine 113 functions by selecting that rule with the “first” Rule Priority 301/401, selecting the “first” Resource Priority group within that rule 302/402, and performing whatever attribution policies exist within that Resource Priority group 304/404. If the REC Obligation 306 and/or Energy Obligation 406 is not met, the system will select the next Resource Priority 305/405 if there is another Resource Priority present 307/407. This continues until the specific Resource Priority is finished. When finished, if there are more rules to run 309/409 the system will select the next Rule Priority 308/408 and again select the “first” Resource Priority group 303/403. At the end, the system will signal completion of both REC 310 and Energy 410 attribution.
For one particular embodiment, a user can decide to what level of accuracy RECs are calculated. The level of accuracy is configurable, to settings such as but not necessarily linked to, configurations in which the values of RECs are always displayed in whole numbers, and any decimal numbers during calculations are rounded to the nearest integer. The system also may allow rounding to commence upon completion of each step in the attribution process 113 via a rounding algorithm or other equivalent operation. This algorithm may operate by rounding each allocation individually using natural rounding, after which the sum of unrounded Resource outputs is obtained and rounded, after which the sum of rounded Resource outputs is obtained, after which the two totals (rounded and unrounded Resource outputs) are compared. If the totals are not equal, individual Resource outputs are individually adjusted in the ascending order of least impact until both totals are equal.
In one particular embodiment, the system may also perform limits monitoring during the attribution calculations 113, defined as validating whether a REC violation exists after every attribution step. If a violation is found, the attribution is stopped and an error message is generated. The system can monitor possible violations such as but not necessarily limited to the inaccurate attribution of RECs. Bilateral Contracts 108 may be marked in such a way that the system tracks whether the percentage of RECs assigned to the contract is less than the percentage of the RECs 101 assigned to the system load; if it is, the system can signal a violation. This monitoring may be configured to happen continuously during attribution.
The system also allows the user to individually create transactions with the Transaction Management tool 114. The Transaction Management tool 114 facilitates the user allocation of RECs to Obligations by specifically setting which RECs from which source are to be allocated. Transactions can be created via the Transaction Management tool 114 both before and after attribution engine 113 is used. If a Resource has already been attributed in some capacity, the Transaction Management tool 114 can take allocated RECs 101 originating from user-created Transactions out of Resource pools so that RECs 101 are not used twice.
After Transactions have been completed in either the Transaction Management tool 114 or the attribution engine 113, the allocated RECs 101 and Energy can be displayed in numerous configurations to communicate a user's final REC position 115. The system may be configured such that scenarios in which Energy delivered to counterparties and markets is in excess of RECs 101 supplied are flagged by the system in a display as containing unbundled RECs 101 which can be sold 116. A user can view this information in graphical format.
The system may also create reports 117. The system may be configured to generate reports 117 such as but not necessarily limited to reports of imported or manually inputted values of RECs 101 and energy. Reports 117 may also be made available which give information on standard bilateral contracts 107 or provide standard energy component reports 117. Flowed energy values, segregated by product, may be displayed after being retrieved by system from imported data 201. Offered and accepted energy values, broken down by product, may be reported after being retrieve from user-entered data. Curtailed energy values for each product may be calculated by subtracting flowed energy values from accepted energy valued.
The system may also generate a report 117 on the generation attribution (by fuel type) for the energy deliveries to foreign entities by organizational permits. This report 117 may be built internally by the system to itemized volumetric deliveries as well as received revenue under organizational permits by generation fuel types. Reports 117 may be generated at any time based upon available Vintage Months.
The system also grants the user the ability to create and view pivot tables with the Transaction data. Once the user specifies a date range, the data populates into a database for display as a chart. The user can then manipulate what information is to be calculated, based on what variables and in what arrangement. The system facilitates user modification of how data is organized in the chart for display by clumping together similar data points into mini-tables within the whole display. In one particular embodiment, the chart configurations may be saved for personal or public viewing or reference.
