In response to Market Participant feedback, the NYISO is providing a permanent Sandbox testing site for select NYISO applications.
The Sandbox environment will remain open and available to Market Participants on a best available effort basis. The NYISO's goal is to provide best available access to the Sandbox 24x7 with the following limitations:
- Daily refreshes beginning at 23:00 each day, lasting approximately 90 minutes
- Planned and unplanned system maintenance
Priority of service is to NYISO production platforms and systems; Sandbox service disruptions will be restored as resources are available during normal business hours.
A Valid NAESB or NYISO Digital Certificate is Required for All Sandbox Links.
