Choice State PSC Orders Creation Of Utility Data Exchange Workgroup, Third Party Access To Utility Data, Part of VPP Order
The following story is brought free of charge to readers by VertexOne, the exclusive EDI provider of EnergyChoiceMatters.com
The Maryland PSC said that it issued an order outlining key directives for Maryland’s electric utilities and stakeholders to, as described by the PSC, accelerate the implementation of virtual power plants (VPPs)
Among other things, the PSC ordered the creation of a new Data Exchange Work Group (DEWG) to draft regulations and parameters for implementation of a state-wide GBC-compliant [Green Button Connect My Data] data exchange platform.
The DEWG shall draft regulations for third-party access to customer data and file these draft regulations within six months
"The final regulations should ensure that, at minimum, Maryland-licensed DERAs [DER Aggregator] have customer-authorized access to customer data, but the DEWG should consider eligibility for additional third parties to maximize use cases and benefits," the PSC said
The DEWG shall develop, within six months, criteria for a request for proposals to develop, implement, and, if necessary, maintain a GBC-compliant data exchange platform that enables permission-based sharing of customer usage and appropriate customer-identifying information
"The platform should incorporate the pillars of data privacy, customer authentication and authorization, data standardization, and third-party registration and onboarding,," the PSC said
In order to promote a customer-friendly experience, the PSC said that, "the DEWG should consider allowing third parties to initiate requests for customer authorization and data sharing, as well as the possibility of native authorization."
The DEWG shall file a model third-party data access tariff two months after a final rulemaking
"The Commission concurs with the Exelon Utilities and stakeholders that reasonable fees for third-party access may be appropriate to alleviate the costs of platform development and maintenance on ratepayers, and the model tariff should include a third-party access fee structure," the PSC said
Regarding a Distributed Energy Resource (DER) Registry, the PSC directed a work group to scope the potential integration of a central, public-facing DER Registry with the new data exchange platform. The PSC said that this acknowledges the need for aggregator access to DER data
The PSC said that Maryland-licensed DER Aggregators (DERAs) shall have access to all PJM-required information held exclusively by the electric utilities no later than January 1, 2028.
The Commission’s Interconnection Work Group was directed to further examine metering and submetering technologies and to develop proposed regulations for device-level metering and communications protocols.
Concerning cybersecurity, the PSC granted more time for the Office of Cybersecurity, in collaboration with utilities and the Cybersecurity Reporting Workgroup, to develop draft regulations.
