Beginning March 1, 2017 all new network transmission customers will be required to submit all applications and related information on the NITS on OASIS. All DNR requests after midnight February 28, 2017 should be done through the NITS on OASIS module. All existing functionality for Network Transmission requests will be disabled at that time.
