What changes for you
The rules that change for battery storage teams.
Storage answers to more moving rules than almost any other resource: how it registers, how it rides through, how it is dispatched and how it is counted.
NERC Category 2 IBR registration
Batteries of 20 MVA or more connected at 60 kV or above register with NERC as inverter-based resources, with dated compliance milestones.
Ride-through, models and cold weather
PRC-024 and PRC-029 frequency and voltage ride-through, MOD-026 model verification and EOP-012 cold weather preparedness.
ERCOT RTC+B
Real-time co-optimization with batteries: state of charge, ancillary service awards and ECRS, as the Protocols are revised.
Capacity accreditation
How each ISO counts storage toward resource adequacy, including ELCC classes in PJM, and the changes each auction brings.
Interconnection
FERC Order 2023 cluster studies and each ISO's queue rules, from application to commercial operation.
Storage tax credits
The 48E investment credit for storage, with Treasury guidance as it is issued.
What you get
What PhronEdge gives battery storage teams.
A registration plan for each battery
Register a storage project in any of the 7 US ISOs and follow its path to commercial operation, milestone by milestone, with the NERC registration steps for Category 2 IBRs.
Obligations mapped per battery
The NERC standards, ISO protocols and state rules that apply to each battery, each one cited.
Changes matched to each battery
When ERCOT revises RTC+B or NERC adopts a new standard, the Attention tab shows which batteries it affects and the action-by date.
Prices beside the rules
Real-time and day-ahead prices, load against peak and grid conditions across the 7 US ISOs in the Market tab.
Cited answers from Relay
Ask how a ride-through rule or a state of charge requirement applies. Every answer cites the standard or protocol section it came from.
Incident response mapping
Report an event and get each reporting duty that applies, with its deadline and who to notify.
How it works
How battery storage teams use PhronEdge, in 3 steps.
Register the battery
Give its ISO, its capacity and where it stands, from interconnection request to operating.
See what applies
The NERC, ISO and state rules that apply to each battery are mapped and cited.
Work the Attention list
Changes arrive matched to the battery, with an action-by date and an owner.
