AI summary

The work order (CI# 34622, dated April 30, 2010) authorizes a two-year, $1,582,587 capital project to raise conductor heights on the L-8002 (Onslow–Lakeside) 345 kV transmission line where spans do not meet minimum Capital Expenditures Canadian Standards Association ground clearance requirements; the project is a continuation of 2009 CI# 33542 ($1.2M actual vs. $1.6M ACE budget).
Work is phased across 2010 ($1,216,050, Brushy Hill to Lakeside) and 2011 ($366,537, Brushy Hill to Brookfield) due to System Reliability transmission line outage scheduling constraints coordinated by the NSPI Control Center.
The project estimate is $75,602 below the $1,658,189 ACE budget, explained in IR-4 as the net effect of reduced capitalized interest (−$109,552, AFUDC at 7.96% annually) partially offset by increased material costs (+$33,950), with interest totalling only $15,922 because a portion of the line enters service before project completion (IR-7).
In response to a Board directive from its August 2009 Order on CI# 33542, Nova Scotia Power Incorporated addressed Affiliate Transactions Code of Conduct Section 2.1(a) compliance, explaining that linework is performed under a 2008–2010 competitive contract with Emera Utility Services (EUS) and that a comprehensive self-provisioning analysis will be conducted before any new affiliate PLT contract is executed after December 31, 2010 (IR-T11(d)).
Material and contract cost figures in IR-3(b) and IR-4(b) are redacted as confidential on the basis that disclosure would impair competitive procurement and increase costs to customers, per the May 31, 2010 cover letter from NSPI's Manager, Capital.
