1 Reliability Analysis Update TEAC Meeting August 20, 2008
2 Northern New Jersey Update Two alternatives are being evaluated to address the issues identified in Northern New Jersey 230 kv Option: rebuild several existing 138 kv lines and associated substations at 230 kv 500 kv Option: extend a new 500 kv line from Branchburg to Roseland to Hudson along with some underlying 230 kv reinforcements PJM has hired an independent engineering firm to evaluate the cost, constructability and effectiveness of each option. Results of the study will be shared with stakeholders at a follow-up TEAC meeting
