Assumption that the max hourly interchange value reached between Jan 2019 - Dec 2023 is representative for available transmission capacity between BA's. — Planned capacity relates to the Ten West Link project which is expected to be operationalized in 2024. The line runs between Arizona Public Service Company (USAAZ) and the territory of CAISO (USACI).
