Exploring costs and benefits of the Dynamic Interchange Adjustment (DINA) tool across market energy trades

A cost/benefit case study was performed to evaluate the results using the Dynamic Interchange Adjustment (DINA) tool to dynamically adjust intertie flows between ISO New England and the New York (NYISO). The DINA tool is designed to provide an online probabilistic estimation of the secure range for possible intra-day and intra-hour net interchange adjustments of a BA within the next dispatch hour. Dynamic adjustment of the intertie flows is a significant potential resource for exchanging energy, capacity and flexibility between Balancing Authorities (BAs) and different markets. The results of the analysis indicated that about 65% of the hours analyzed had a potential for additional exports or imports, and a significant economic benefit was found compared with the costs of implementing the tool. The approach used in this study opens up a potential opportunity for trading near-real-time energy and capacity between different markets.
