Transmission constraint relaxation parameter change
Currently the ISO market software relaxes transmission constraints whenever the constraint’s shadow price hits a threshold of $5,000. When this occurs, high shadow prices and corresponding locational marginal prices, coupled with the reduced constraint limits, cause high real-time congestion offset costs. The ISO proposes reducing the threshold to $2,500 in the real-time market only, which will still allow for effective flow mitigation through market optimization.
