天然气：美国东北部对加拿大电量的依赖日渐减弱

Group 1: Report Core Findings - The net electricity input from Canada to New York (NYISO) and New England (ISO-NE) has been continuously declining. From January to August 2025, ISO-NE's average daily net imported electricity from Canada decreased by over 60% compared to the same period in 2022, and NYISO's net transaction volume with Canada shrank to 25% of the same period in 2022 [1][3] - The decline in imports is mainly due to two factors: Canada's widespread drought in the past three years leading to reduced hydroelectric power generation, and the decreasing electricity demand in both NYISO and ISO-NE. From 2016 to 2024, ISO-NE's electricity demand dropped by 9% and NYISO's by 6% [1][3] - The trend of power import decline will indirectly determine the natural gas supply in North America, and continuous tracking of this trend is necessary [1] Group 2: ISO-NE Import Situation - When ISO-NE's electricity demand is high, Canadian power is crucial. In January 2025 during the winter peak, Canadian power accounted for 14% on average, but the average in the first eight months of 2025 was only 5%. From 2016 - 2022, it contributed 14% on average, dropping to 11% in 2023 and 5% in 2024 [6] - ISO-NE first had a net export to Canada on a single - day basis in February 2023. Such net exports became more frequent, with 49 days in 2024 and 20 times as of August 31, 2025 [6] Group 3: NYISO Import Situation - Canadian power was an important source for NYISO, but imports have been decreasing. From 2016 - 2022, Canadian power accounted for 11% of NYISO's supply on average, dropping to 5% in 2023, 3% in 2024, and about 2% as of August 31, 2025. In August 2025, NYISO had a net export to Canada on all but three days [9] - NYISO first achieved a single - day net export to Canada in July 2023. There were 87 days of net export in 2024, and 86 days as of the end of August 2025 [9]
