The LIPA Method, as calculated by ISO-NE, determines a tie benefit criterion of 2,540 MW with neighboring systems. Despite ISO-NE not providing reasoning for any inadequacies in the LIPA Proposal, the MA AG suggests implementing a 10% discount to address potential concerns. This adjustment brings the calculated tie benefit down to 2,286 MW. The proposal is aimed at ensuring transparency and confidence in the methodology’s application, especially given that this approach has not been previously used by ISO-NE for tie benefit calculations.

MA AG Proposal Tie Benefit Calculation For 3rd ARA
LIPA Method • The LIPA Method, calculated by ISO-NE, is an at criterion method. • It results in a tie benefit (Case I) with neighboring systems of 2,540 MW (See PSPC lipa_proposal_9_3_2009.pdf as posted on ISO-NE Web Site) • ISO-NE has not articulated why the LIPA proposal is in any way inadequate.
LIPA Proposal Cont. • Since the LIPA Proposal hadn’t been used before by ISO-NE, the MA AG is willing to propose a discount to the tie benefit of 10% to assuage any ISO-NE concerns • 2,540 MW less 10% is a 2,286 MW tie benefit.
