16 Feasibility of 500 kv underground cables 16
17 Feasibility of underground cables: conclusions Is an underground cable system feasible? Yes Underground 500 kv cable is technically feasible Cross linked polyethylene (XLPE) cable is best choice Proviso: manufacturers must validate cable and accessories on test to: IEC 62067: Accelerated aging prequalification for one year Special low ambient temperature test 17
18 500 kv cable types considered Feasibility study XLPE extruded SCFF LPP taped 18
19 500 kv XLPE cable has benefits of: Lowest losses of conventional cable types Solid (unpressurised) insulation: No possibility of fluid leakage from cable Lower maintenance Reduced risk of fire Alternative cable is SCFF (Self Contained Fluid Filled): Becoming obsolete Risk of fluid leakage 19
20 Other technologies evaluated: Gas insulated Line (GIL) Not yet proven for burial in long length circuits Some environmental concern Feasible alternative for tunnel (long length) Courtesy Siemens 20
21 Other technologies evaluated: Feasibility study High Temperature Superconducting Cable (HTS) Not yet sufficiently developed for high power, long length circuits with joints Courtesy NKT 21
22 Feasibility of power rating 22
23 Feasibility of power rating Can a cable system carry the 3,000 MW needed? Yes Suppliers design proposals: Largest standard conductor size: 2,500 mm 2 copper Two groups of cables per circuit Most efficient installation method: direct buried Typical design: Up to four trenches x three cables per trench = twelve cables (Study also evaluated scenarios with fewer groups of cables) 23
24 3,000 MW: Contingency operation Feasibility study 24
25 Six cables required per circuit: To carry 3,000 MW peak load in contingency operation 1,500 MW maximum per group of three cables 25
26 3,000 MW: Normal operation Feasibility study 26
27 Supplier Capability & Experience Has the cable system been used before at 500 kv? Yes, the cable has been used before at 500 kv But, no evidence to date that the offered joint types have been fully proven Three installations of 2,500 mm 2 cable with joints to date Three suppliers have this 500 kv experience 400 kv experience is a good indicator of prospective supplier capability Examples follow 27
28 500 kv, 2,500 mm 2, Tokyo tunnel: 2 x 40 km routes (240 km) Commissioned in 2000, 9 years good experience 4 suppliers In a warm, dry tunnel Courtesy Viscas 500 kv cable is available Courtesy J-Power Systems Extrusion moulded joint no longer offered 28
29 500 kv, 2,500 mm 2, Shanghai tunnel: 2 x 17 km routes (102 km of cable) To be commissioned in suppliers 2 types of prefabricated joint Feasibility study Courtesy Viscas Prefabricated joints on proving test Courtesy Viscas Pulling 500 kv cable into tunnel 29
30 500 kv, 2,500 mm 2, 2 routes in Russia, in tunnel 2 x 0.8 km routes (4.6 km of cable) Commissioned in 2008 and supplier 6 prefabricated joints Courtesy Nexans Outdoor terminations Courtesy Nexans Gas immersed terminations 30
31 400 kv, 1,200-2,500 mm 2, experience Cumulative 351 circuit km (1,053 km cable) 34 projects completed or under construction 21.3 km,1,600 mm 2, direct buried, installed km, 2,500 mm 2, direct buried, installed km, 2,500 mm 2, tunnel, installed 2005 Courtesy Brugg Prefabricated one piece joint mould Courtesy LS Cable Prefabricated composite joint 31
32 500 kv Project size How big is the 500 kv study project? It would be one of the largest in the world: 4 groups of cable in 20 km route require 240 km of cable ~360 joints. Equal to 40 km Tokyo circuit First application of buried, long length, large conductor 500 kv cable with joints. 400 kv buried experience is relevant. 500 kv is the highest voltage for XLPE to date 3,000 MW is a high power level. The combination of voltage and power requires a cable size at the top end of standard manufacturing ranges. Such cables are available 32
33 Project specific requirements 33
34 500 kv Project specific requirements Feasibility study Location specific: Crossing of route obstructions Highways: multi-lane and banked Pipelines: petrochemical, heated? Wetlands and streams Obstructions are normal for cable routes, but ability to maintain ampacity needs to be confirmed Low ambient temperatures Direct buried joints: -15 o C design Outdoor terminations: -50 o C design Lack of low temperature experience from suppliers. Concern about elasticity of the rubber insulation in accessories 34
35 Proving of performance 35
36 Proving of performance Feasibility study Should performance of cable system be proven before being supplied? Yes, both electrical and mechanical prequalification tests and low temperature tests must be performed Proving tests: these are normal before supply Prequalification test: one year Type test: 6 weeks Special proving tests: low temperature tests to be formulated 36
37 Proving of performance Feasibility study Courtesy Nexans Prequalification test Courtesy Sudkabel Type test 37
38 Reliability 38
39 Reliability Would XLPE cable system be reliable? Feasibility study Yes, Subject to performing proving tests and quality control in manufacture and installation Recommended proving and quality tests must be done Utilities are demonstrating confidence in reliability and maintenance by installing XLPE. They reduce risk by requiring high standards of design to installation Statistics of cable systems: Repair time 29 days. Faults : 1 x 10 km group per year Dig in faults 25% of above Majority of internal failures accessories Reliability analysis needed for all equipment Service experience of XLPE cable is comparatively short and needs to be monitored 39

72 Project risks 72
73 Project risks What are the project specific risks? There are three risks: Feasibility study 1) Inability of 500 kv accessories to operate at Edmonton winter temperature Preventative Gather low temperature information from manufacturers Draft low temperature test specification Require manufacturers to perform this test Remedial Install joints at greater depth This may require an additional group of cables to meet 3,000 MW requirement Install cables in tunnel with controlled air temperature 73
74 Project risks What are the project specific risks? Feasibility study 2) Uncertainty of actual minimum winter temperature Preventative Field trials to measure ground temperature Remedial: Increase accessory design temperature margins Evaluate trace heating Install cables in tunnel 74
75 Project risks What are the project specific risks? Feasibility study 3) Long time required to repair cable in winter Preventative Specify the maximum winter repair time requirement to suppliers in the Request for Quotation Develop a winter repair procedure Design and build mobile heated habitat* for winter repair use Perform trials to prove the winter repair procedure Install more groups of cable to allow longer repair time Remedial Contingency switch the load onto parallel circuit Repair the accessory when the ambient temperature rises *Note: use of mobile jointing habitats is normal in temperate climates 75
76 Project schedule 76
77 Project schedule How long would it take to manufacture and install? 10 km, 4 groups Unstaged 57 months Staged (stage 1 only) 46 months 10 km, 3 groups Unstaged 57 months Staged (stage 1 only) 46 months 20 km, 4 groups Unstaged 57 months Staged (stage 1 only) 57 months 20 km, 3 groups Unstaged 57 months Staged (stage 1 only) 57 months 77
78 Recommendations for next steps 78
79 Recommended Next steps What are the next steps in evaluating underground cable? Refine and optimize cable system: Investigate joint low temperature protection by installation at greater depth Detailed designs for obstruction crossings. Is ampacity OK? Quantify reliability and availability for all circuit components Refine accuracy of the cost estimates Discussions with cable suppliers to agree: Normal proving tests Specific proving tests Discussions with cable suppliers on schedule shortening: Is evidence available for 500kV XLPE : Existing electrical and mechanical prequalification and type tests Ongoing installations and tests Low temperature test and service experience 79
80 Summary 80
81 Summary What are the main findings? Feasibility study 500kV, 3,000 MW, underground cable is feasible The power rating is feasible for normal burial depth. A study of specific obstruction crossings is required: Dimensions and temperatures Their effect on circuit power ampacity XLPE insulated cable is the best choice. Service and test experience exists for 500kV XLPE cable and terminations in temperate climates. No evidence exists of tests on joints at Edmonton low winter temperatures Evidence of tests is essential. (Continued) 81
82 Summary What are the main findings? Feasibility study Edmonton low winter ambient temperature is a project specific risk to the joints and terminations. Low temperature testing is essential. Ground temperature with depth to be measured: Winter Summer Cable optimization: ampacity benefits of: Cyclic rating study Lower summer ground temperatures at depth 82
