Jiangsu Province is characterized by high load density and a large share of electricity consumption by the manufacturing sector. Its power system faces multiple constraints, including continued growth in electricity demand, large-scale integration of renewable energy, and limited local primary energy resources. Considering the province’s electricity-load characteristics, geographical resource conditions, industrial structure, and renewable-energy development trends, this study takes the period around 2030 as the medium-term planning horizon and develops a scenario-analysis framework for multi-source–multi-storage configuration from the perspective of annualized total system cost. The results indicate that a relatively low-cost power-supply pathway for Jiangsu cannot be achieved simply by increasing the share of a single type of power source. Instead, it requires an integrated portfolio consisting of flexible thermal power for supply adequacy, orderly expansion of offshore wind power and distributed photovoltaic generation, coordinated deployment of multiple energy-storage technologies, and an appropriate level of imported electricity. It is recommended that thermal power gradually shift from an energy-supply role toward capacity support and system regulation; wind power development should focus on coastal and offshore areas; photovoltaic development should prioritize industrial and commercial distributed projects and fishery–photovoltaic complementary projects; and energy storage should be configured through the coordinated deployment of electrochemical storage, pumped storage, compressed-air energy storage, flow batteries, flywheels, and other mechanical energy-storage technologies. This configuration can help reduce the system costs associated with renewable-energy curtailment, peak regulation, reserve capacity, and transmission and distribution expansion while maintaining power-supply reliability, thereby providing a reference for the planning of a new-type power system in Jiangsu Province.
