A brand new report from researchers at Princeton College discovered that probably the most cost-effective pathway for New Jersey to achieve 100% carbon free electrical energy by 2050 entails a major quantity of imported electrical energy.
The 186-page examine – known as New Jersey’s Pathway to a 100% Carbon-Free Electrical energy Provide: Coverage and Expertise Decisions By means of 2050 – was developed by the Zero-carbon Power Methods Analysis and Optimization Laboratory (ZERO Lab) at Princeton.
“New Jersey is amongst a vanguard of states pursuing a transition to 100% carbon-free electrical energy. Our purpose for this examine: present an in depth, impartial evaluation of key coverage and expertise choices and selections and their implications for NJ’s pathway to 100% carbon-free,” Jesse Jenkins, chief of the ZERO Lab and an assistant professor at Princeton College, tweeted in regards to the report.
Jenkins authored the report with QingyuXu, Neha Patankar, and ChuanZhang from the ZERO Lab.
The examine explores the function of in-state photo voltaic PV, offshore wind, nuclear energy, and imported electrical energy within the state’s electrical energy future. Among the many key findings, the examine mentioned {that a} transition to 100% carbon-free electrical energy is possible whereas sustaining reliability and lowering bulk electrical energy provide prices. Additional, it exhibits the lowest-cost technique to achieve 100% carbon-free electrical energy provide requires a major improve within the state’s dependence on imported electrical energy.
It provides that imports of wind, photo voltaic, and different carbon-free sources from out of state are usually extra inexpensive than accessible in-state sources. This is able to be a departure from New Jersey’s present coverage strategy, which prioritizes in-state and distributed era.
The examine additionally revealed that as a result of electrification of automobiles and buildings in keeping with the state’s local weather objectives, electrical energy demand might improve considerably — as much as 85 p.c at peak demand — whereas patterns of consumption might shift dramatically.
It additionally finds that import dependence may very well be lowered by requiring in-state renewable sources and preserving the state’s present nuclear reactors. Essentially the most inexpensive technique to prioritize in-state sources will increase bulk electrical energy provide prices by 7 to 10 p.c relative to the least-cost 100% carbon-free pathway. Nevertheless, it nonetheless leads to prices corresponding to or decrease than as we speak.
Lastly, the researchers level out that if states within the area pursue parallel deep decarbonization objectives, the prices of reaching 100% carbon-free electrical energy in New Jersey will improve by 16 to twenty p.c. Bulk electrical energy provide prices in 2050 vary from -13 p.c to +11 p.c relative to 2019 prices if all states within the area pursue 100% carbon-free electrical energy.
The ZERO Lab researchers used a state-of-the-art open-source electrical energy system optimization mannequin, GenX, which plans funding and operational choices to fulfill projected future electrical energy demand whereas assembly all related engineering, reliability, and coverage constraints on the lowest price. They created an in depth mannequin of the electrical energy system of New Jersey, the PJM Interconnection, and neighboring grid areas.
