The New York Independent System Operator (NYISO) has put out its 2024 Reliability Needs Assessment (RNA), and it’s raising big concerns about the future safety of the state’s electric grid. The report points out that there are reliability gaps that might show up as early as 2033, particularly regarding New York City’s capacity to handle peak electricity use.
Projected Shortfalls
The RNA predicts a shortfall of 17 megawatts (MW) in the summer of 2033, which could grow to 97 MW by the next year. These results underline the urgent need for strategic measures to tackle the increasing risks faced by the state’s electrical system as it encounters unique challenges.
Factors Behind the Risks
There are several reasons for the rising risks noted in the assessment, such as the growing electrification of transportation and buildings, which is likely to increase the demand for electricity. Large commercial developments, like data centers and chip-making plants, make the situation worse by adding significant energy loads to the grid.
Moreover, the new legislation in 2023 that requires the closure of small natural gas plants owned by the New York Power Authority (NYPA) in New York City and Long Island will see a reduction of 517 MW of capacity, putting even more pressure on the system’s reliability.
The Changing Grid Landscape
The RNA also points out that the grid is changing, shifting from a summer-peaking to a winter-peaking system due to more electrification. As more buildings and vehicles depend on electricity for heating and transport, winter demand is expected to rise sharply.
This change brings new difficulties for grid operators, especially regarding fuel supplies for gas-fired power plants. On the chilliest days, natural gas companies focus on providing residential heating over electricity needs, which limits the fuel available for power plants, raising concerns, especially since these cold days align with peak winter demand.
Potential Solutions
To tackle these reliability issues, the NYISO suggests various solutions, including adding new capacity resources, expanding transmission infrastructure, and increasing involvement in demand response programs. Completing vital transmission projects on time, particularly the Champlain Hudson Power Express (CHPE), is critical for maintaining system reliability. If the CHPE isn’t operational by May 2026, along with other compensatory actions, the report warns that reliability levels in New York City may fall short, jeopardizing the grid's ability to meet future needs.
