17. Pad-mounted Switchgear Replacement - The Underground Equipment Inspection Program has identified a requirement for replacement of air insulated pad-mounted switchgear units, with dead-front stainless steel enclosure SF-6 Gas Insulated Equipment, due to corrosion and contamination issues, which will continue at a rate of 1-Units per year. Project scope involves the installation of applicable civil works such as manholes and duct-banks associated with the equipment replacement to current standards, using equipment constructed of Stainless Steel to avoid corrosion issues. Increased system reliability, Public & Personnel safety, and functionality are benefits of the program.

18. Line Relocations due to Municipal Road Improvement requirements - An allowance is maintained for the relocation/construction of distribution facilities to resolve conflicts with planned road works by such Governmental Agencies as the M.T.O., Regional Municipality of Niagara and the various Municipal Agencies within the Service territory. Additions and reinforcement to the distribution system resulting from new construction requests fall under this budget. Tracking is accomplished with individual Project Numbers assigned to the various projects as required within the Corporate Accounting System.

19. Pole Replacement - Poles identified with limited Structural Integrity - The natural degradation of wooden utility poles is an ongoing issue. NPEI performs a site visit of every distribution pole on the System as per OEB requirements (3 years/urban, 6 years/rural), with a total population of over 37,000. The pole is tested for its integrity, a visual inspection is performed of the equipment installed on the pole by qualified Linesmen, the pole is imaged, guy guards are installed & down grounds are repaired/replaced as required, and the inspection results and images are stored within the Geographical Information System (GIS). An evaluation of the results is performed, with deficiencies addressed by the replacement of deficient poles, in a timely manner, through this Capital Program. The average cost per pole change is approximately $ 5,000.

20. Kiosk Replacement - With Pad Mounted Transformers - Prior to the advent of pad-mounted Transformer & Switchgear Equipment, supplying loads larger than could be supplied by pole mounted equipment, or areas serviced from underground primary distribution systems, lead to the development of ground mounted masonry enclosures housing high voltage transformation, switching & protection apparatus, and secondary distribution equipment, known as the Kiosk. These block structures were meant to provide Public Safety but over time, the structures deteriorate and warrant replacement. These are prioritized utilizing the results of a 5-year Conditional Assessment Survey last completed in 2018. This Capital Program is an integral part of the remediation of underground distribution systems, increasing longevity and reliability within the area serviced. As these legacy components are replaced, safety, reliability and service quality are significantly improved. For 2020 the plan is to replace 1 unit.

21. Smart Grid - Installation of smart technologies onto the distribution system. These technologies include reclosers, fault indicators and switches. These devices will communicate real time system status to our Operators allowing them to make better decisions when operating the system. The devices will also be remotely operable by the Operators via our existing WiMax network. This will be an annual program which focuses on modernizing our distribution system to improve both system reliability and efficiency.

22. System Sustainment Allowance - This Capital Program manages an allowance for minor projects initiated by unexpected failures/deficiencies of overhead and underground distribution facilities. Replacement of underground cable experiencing repeated failures is a major contributor covered by this allowance. Minor overhead system modifications and component replacements are also accounted for.

23. New Residential Services (Subdivisions) - This Capital Program manages the installation and connection of new residential services within new and on-going residential developments such as subdivisions.

24. Demand Based System Reinforcements for New Commercial Service Connections - This Capital Program manages an allowance for the construction/upgrade of distribution equipment to facilitate system access connections of new commercial developments. Expansions and reinforcement to the distribution system resulting from these new customer connection requirements fall under this budget allowance.

25. Metering - General - This Capital Program manages an allowance for the metering equipment to facilitate system access connections of new commercial and residential developments. Metering costs resulting from these new customer connection requirements fall under this budget allowance.
