Pennsylvania Gov. Favors DER Aggregator Access To Customer Usage Data, Opposes Reliance On EDI
The following story is brought free of charge to readers by VertexOne, the exclusive EDI provider of EnergyChoiceMatters.com
In comments to the Pennsylvania PUC, the Office of Pennsylvania Governor Josh Shapiro favors the expansion of utility customer usage data sharing to distributed energy resource (DER) aggregators, but opposed delegating a mechanism for such sharing to the Electronic Data Exchange Working Group (EDEWG), with the Governor's office favoring the use of Green Button Connect
The comments from the Governor's office were made in a PUC proceeding addressing the participation of distributed energy resources (DERs) in the PJM markets
Currently, only licensed electric generation suppliers (EGSs, which include brokers and retail energy aggregators) may obtain customer data from the utility
While the PUC proposes to expand data access to DER aggregators, the PUC's proposal would delegate the matter to the EDEWG, rather than setting customer data sharing standards in an instant order
"Delegating the development of data-sharing standards to the EDEWG is unnecessary because a proven data-sharing framework -- Green Button Connect -- already exists, as other parties to this docket have discussed. Moreover, the EDEWG is not well-suited to developing data-sharing standards for DERs. To date, the EDEWG’s Commission-assigned role has been to help implement EDC Electronic Data Interchange ('EDI') systems for retail market transactions, which have data needs that are qualitatively different from those of companies aggregating DERs in real time," the Governor's office stated
"Deferring details to the EDEWG and EDC filings will cause unnecessary delay in the development of data-sharing standards and risks leading to fragmented implementation and insufficient data sharing methods that may not meet state or federal statutory standards," the Governor's office stated
The Governor's office said that the PUC should require the EDCs’ data sharing arrangements to be compliant with the latest version of the "Green Button Connect My Data" standard established by the Green Button Alliance, or such succeeding standard as the Commission may approve that allows for Application Processing Interface (API)-based automated and secure sharing of granular data.
The Governor's office further said that the PUC's order should identify a minimum set of data fields that the EDCs are required to share with DERAs, including all data required by PJM, now or in the future, for wholesale market participation. This includes revenue-grade energy usage, customer name, account number, premise address, transmission zone, and peak load contribution (PLC). EDCs should also be required to provide data that DERAs need to determine the eligibility of a customer to participate in wholesale markets, which currently includes whether the customer has a net-metered resource, the Governor's office said
The Governor's office said that the PUC should also require EDCs to provide DERAs with settlement-quality usage data within 24 hours after the moment of energy usage, and on a real-time basis where metering technology allows.
The Governor's office said that the PUC should also require EDCs to provide DERAs with usage data at a granularity of 15-minute intervals, and to be capable of providing 5-minute intervals if requested by a customer by the time of PJM’s implementation date of FERC Order 2222.
The Governor's office also requested that the PUC narrow the proposed prohibitions on net metering customers participating in the PJM markets, with such proposed restrictions intended to prevent double-counting
The Governor's office said that the PUC should allow more flexibility for resources to participate in both net metering and the wholesale energy & capacity markets, if tariffs or methodologies are updated to ensure that these services are not double-counted
"The PUC should draw from the 'release valve' methodology proposed by PJM to allow energy and capacity interconnection requests to be net energy metered after being closely scrutinized and confirmed to not be double counted. The PUC could consider leaving final determination of double counting to EDCs," the Governor's office said
Additionally, the Governor's office said that the PUC should standardize EDC review procedures for DER aggregations, including the standardization of utility fees
