Customer Change Team Leader


The Retail Energy Code Manager will, in accordance with the REC Change Management Schedule, request from identified Service Providers (of which the CDSP resides) various levels of Impact Assessments in relation to REC Change Proposals. 


These impact assessments will conform to various deadlines for delivery and should cover any impacts/cost/delivery timescales in relation to CDSP Systems/Services, CDSP Service Provider System/Services & CDSP Customer System/Services (where appropriate).


It is anticipated that there will be three levels of Impact Assessments being formally requested by the Code Manager:


Standard Impact Assessment - 5WD

Preliminary Impact Assessment - 15WD

Detailed Impact Assessment - 40WD (Timeframe may differ depending on approval from the Code Manager)


The CDSP (and it's service providers) need to ensure that the appropriate level of detail is provided back to the REC Code Manager within the agreed timeframes to ensure adherence with the REC performance standards (PAB).
