Tagging inside the platform that runs your book.
e-Tagging is usually a separate tool bolted onto everything else. ennrgy.com built it into the same platform that runs your scheduling and risk, with NAESB compliance, coverage beyond the seven U.S. ISOs into IESO and NBSO, and a desk that can tag on your behalf. Our team helped author the NERC e-Tag specification.
