New York’s Climate Leadership and Community Protection Act (CLCPA) requires an unprecedented transformation of the State’s electricity grid to achieve 70% renewable generation by 2030, zero-emission electricity by 2040, and an 85% economy-wide reduction in greenhouse gas emissions from 1990 levels by 2050. The CLCPA specifies minimum amounts of certain types of resources, including 6,000 MW of distributed solar resources by 2025, 3,000 MW of storage by 2030, and 9,000 MW of offshore wind (OSW) generation by 2035. Even greater quantities of various types of renewable generation are necessary to achieve the clean energy mandates for 2040 and 2050. Meeting these milestones will require investment in renewable generation, as well as storage, energy efficiency measures, electrification of the transportation and heating sectors, and electric transmission and distribution (T&D) infrastructure.
The Power Grid Study is a first step toward planning the investments in New York’s electric system that are needed to meet CLCPA goals. It provides valuable information to the State, utilities, and transmission and renewable generation developers. However, cost-effective transmission development and utilization of the existing grid requires foresight and coordination that will necessitate the continuation of active planning, coordination, and process management. Without them, challenges and costs will likely exceed those identified in the studies. For the State to cost-effectively achieve its CLCPA milestones, this report offers the following recommendations for further consideration by the PSC and State policy makers.
