2013 Sees Reduction in Collector System Installation Performance
Renewable energy generators should plan for more than a 20% increased risk of unplanned outages on sites commissioned in 2013.
MANCHESTER, Conn., March 3, 2014 IMCORP, the exclusive provider of the Factory Grade® test for power cable systems, has released the 2013 Annual Cable System Quality Rating for utility-scale renewable energy sites in the United States. Based on thousands of new cable systems assessed annually, IMCORP maintains the most comprehensive database of medium and high voltage cable installation performance data in the world.
In the US during 2013, 84% of cable systems installed at utility-scale renewable energy sites met the manufacturers' quality control standards on initial test (The Cable System Quality Rating, or CSQR). In 2012, the CSQR for the US renewable industry was 87%. In its history, 2013 was the first time that the CSQR declined for back to back years. This downward trend is concerning to any site owner, operator, insurer, or power purchaser.
The average utility-scale renewable site contains approximately 100 medium voltage cable segments. Therefore, without using the Factory Grade® test to assess the condition of the cable system and then making pre-energization repairs , the average 2013 facility is at risk for 16 cable system failures prior to the end of the design life. This represents more than a 20% increase of at-risk cables at each facility over sites constructed in 2012. However, renewable energy sites utilizing the Factory Grade® test have located, mitigated, and will avoid outages associated with these embedded
