The posting of documents on this website is done for the convenience of ISO New England's market participants and other interested visitors to the website. The user should be advised that, while ISO New England attempts to conform all posted documents to the original version, there can be changes resulting from the programs used to format the documents for posting on the website as well as from the programs used by the viewer to download and read the documents. Accordingly, ISO New England makes no representation or warranty, express or implied, that the documents on this website (and collectively with all information and data on this website, the "Content") are exact reproductions of those documents listed.

The Content is subject to change or termination without notice. The Content is provided on an "as is" basis. ISO New England, to the fullest extent permitted by law, disclaims all warranties, either express or implied, statutory or otherwise, including but not limited to the implied warranties of merchantability, non-infringement of third parties' rights, and fitness for particular purpose. Without limiting the foregoing, ISO New England makes no representations or warranties about the accuracy, reliability, completeness, date, or timeliness of the Content. All persons using this website (collectively, "you") agree that ISO New England shall have no liability to you based on your use of or reliance on the Content or the website.

Because not all issues and requirements are addressed by the Content you should not rely solely on the Content for information but should consult the effective Transmission, Markets and Services Tariff (“Tariff”) and the relevant Market Manuals, Operating Procedures and Planning Procedures (“Procedures”). In case of a discrepancy between the Content and the Tariff or Procedures, the meaning of the Tariff and Procedures shall govern.

All ISO New England and stakeholder-submitted material marked as "Critical Energy Infrastructure Information" or "CEII" or the like is located in a restricted area of the website. Note that while ISO New England posts stakeholder-submitted material marked CEII to this restricted area of the website, it is not otherwise responsible for reviewing, categorizing, or protecting materials submitted by stakeholders. Access to these restricted areas is limited to "Authorized Users" who have completed a registration process and who have then been granted authorization for access through issuance of a unique digital certificate. No persons other than Authorized Users may access these protected areas of the site. The digital certificates are non-transferable. ISO New England will not be responsible for authenticating the identity of any person accessing the protected area of the Site with a digital certificate. As an Authorized User, you are solely responsible for maintaining the security and confidentiality of your certificate, and accordingly, you are liable for all access, use and activities on the protected area of the Site under your certificate, even if such use is unauthorized. Should you become aware that an unauthorized third party has attempted to access protected areas, or in the event of any other possible error, misuse or fraud relating to the Site, it is your responsibility to inform us immediately so we may take appropriate action. We reserve the right to terminate any Authorized User's access to and use of the protected area of the Site at any time, and without notice, for any reason including, but not limited to, any possible or alleged misuse, abuse, violation of law, fraud, or misconduct.

The data in the protected areas of the site may be either "Critical Energy Infrastructure Information" or information that is otherwise protected under the terms of ISO New England's Information Policy. You are responsible to treat all information in protected areas of the site in accordance with those designations and your obligations under the ISO New England Information Policy even if such information is not labeled.

You are also hereby put on notice that the Content is protected by copyright under United States laws. Any duplication of the Content or non-personal use may violate copyright, trademark, and other laws.

You agree to defend, indemnify, and hold ISO New England, its officers, directors, employees, agents, licensors, and suppliers, harmless from and against any claims, actions or demands, liabilities and settlements, including without limitation, reasonable legal and accounting fees, resulting from, or alleged to result from, your violation of these Terms and Conditions.

The website uses "cookies," which store small amounts of data on your computer. Cookies assist ISO New England in tracking use of the Web site. You have the ability to accept or decline cookies by modifying your browser.

You may not use the website in any manner that could damage, disable, overburden or impair any ISO New England server(s), or the network(s) connected to any ISO New England server(s), or interfere with any other party's use of this Web site. You may not attempt to gain unauthorized access to this website or any services, other accounts, computer systems or networks connected to any ISO New England server or to any of the services, through hacking, password mining or any other means. You may not obtain or attempt to obtain any materials or information through any means not intentionally made available through this Web site.

ISO New England will monitor the performance of the website and the amount of requests and bandwidth used. In the event of excessive bandwidth, excessive concurrent requests, or invalid URL requests, ISO New England may, at its discretion, employ a throttling mechanism to mitigate any degradation of service. The process of enabling and disabling throttling of incoming connections is done by IP address.

Activity that may be considered excessive usage includes, but is not limited to:

  • Bandwidth by IP address. A volume of megabytes by IP address sent or received per time period.


  • Concurrent Requests. A number of requests by IP address to the same URL per time period.


  • Invalid URL Requests. A number of invalid URL requests by IP address per time period.

The determination of excessive usage will be made by ISO New England personnel reviewing access logs, notification of reduction in service to the Web site, or by other means. In all cases when it is discovered that excessive usage is occurring the IP address of the offending process will be throttled.

In the case where an IP address has been throttled, ISO New England will do its best to identify the source of the requests. Whenever possible, impacted companies will be notified that throttling is occurring. To assist the ISO with communications with Market Participants, please verify your company has identified an "Emergency IT Contact" in ISO New England's Customer and Asset Management System (CAMS). Once throttling is occurring, ISO New England will verify that excessive usage has been eliminated before throttling is removed. In the case where the source of the IP is not known, the IP address will remain throttled until ISO New England has verified that excessive usage has been eliminated.

ISO New England reserves the right to take additional steps, including blocking access to its Web site, if excessive
usage continues.
