Changes
Since last year:
1) 2014 load forecast decreased by 30 MW vs. 2013
2) Error on Kern PP #4 230/115 model corrected
3) New limiting contingency and element
4) LCR has decreased by 62 MW
5) 2018 load forecast has increased by 17 MW vs. 2017
6) Long-term LCR has increased by 40 MW
Since last stakeholder meeting:
1) Updated NQC
2) Updated LCR results base on new effectiveness factors
