EL CENTRO â€“ The IID Board of Directors approved a recommendation by IID Energy Manager Vicken Kasarjian to cancel the Path 42 Special Project System (SPS) Tuesday at their regular meeting.
The Path 42 SPS had been initially presented and approved by the board back on November 13, 2012.
The SPS was a relay-protection project needed to curtail generation interconnected to IIDâ€™s Midway and Highline substations for outages onÂ transmission lines in the Coachella Valley area.
The SPS was intended to increase IIDâ€™s ability to export powerÂ from renewable energy sources in the ValleyÂ and minimize merchant tripping during a loss of the 230-kv NK/KS line between Coachella Valley Substation to the Devers and Mirage substations.
According to, and under the direction of Kasarjian, a recent assessment by staff of the transmission system determined the Path 42 SPS project is not needed for reliability or to resolve any system instability issues.
The total project cost was estimated to be $5,877,157. Expenditures to date are $4,172,329.
The Ramon Bank No.2, 230/92-kV 225 MVA Transformer Addition, was also cancelled for the same reasoning.
The project consisted of installation of a new 230/92-kV 300 autotransformer at the Ramon Substation. Total estimated cost was $12,503,101 over a three-year period.
â€œTo continue with these projects would put an unnecessary burden upon IID at this time,â€ said Kasarjian. â€œTherefore, we would like to cancel them.â€
â€œThere were thorough assessments re-issued on this project?â€ director James Hanks asked.
â€œYes, Sir,â€ said Kasarjian.
Director Stephen Benson asked if there were other uses for the equipment already purchased for the project.
Kasarjian said he would look in to it and get back to him.
The directors raised several concerns about not doing the upgrades, but Kasarjian said that the systems are capable of handling whatever comes along.
â€œWe have done several studies, including contingencies,â€ said Kasarjian. â€œWe actually overloaded our system beyond our worst case scenario for summer operations of IID by another five percent and we did not see any issue.â€
