    This report provides unit cost estimates for transmission lines and facilities in NorthernOntario and the Far North.

    1. Overview

    For the purposes of this study the delineation between “Northern Ontario” and the “Far

    North” will be used as defined by the Ontario Ministry of Natural Resources (see Map 1

    in Appendix 1). Northern Ontario includes the region north of Sudbury from Manitoba to

    Quebec extending to the Far North Boundary. Most of this area is currently connected

    to the grid and most communities have all season road access. In the Far North, there

    are 26 remote communities (communities not accessible by all-season roads) and theTown of Pickle Lake. The majority of communities in the Far North are not connected to

    the grid and are powered by local diesel systems. Of these remote communities there

    are 20 which are located north of Pickle Lake, for which the OPA has been directed to

    develop a plan for transmission connection.

    For the purposes of this study, it is assumed that public lands are owned by the Crown

    and access rights must be acquired from the Crown. The project cost information,

    therefore will not include considerations of First Nations Impact-Benefit Agreements as

    they are difficult to quantify and are assumed to be settled through consultation and

    negotiation within the context of any specific project.

    This deliverable will identify and summarize each facility type and cost category, the

    costs of building transmission lines and facilities in the remote areas of the Far North

    separately from the rest of Northern Ontario. Some of the conditions that are expected

    to be encountered in remote locations include lack of road access or limited seasonal

    road access, reduced work seasons for completing EAs and other development and

    construction work and operating in rough undeveloped terrain.

    2. Study Methodologies and Assumptions

    Remote community connections include development of transmission line corridors to

    enable grid connection. In order to select the line options and the location of

    transformer stations it will be necessary to map a full range of environmental criteria as

    well as the surficial geology so that sensitive features or areas can be avoided. Some

    of the general environmental criteria which can be mapped to assist with the route

    selection include:

    •  Ecological Areas of Concern (Vegetation/Wildlife);

    •  Land-cover/Land-use;

    •  Species at Risk Habitat/Breeding Areas;

    •  Land Ownership;

    •  Road Networks;

    •  Existing Transmission Lines;

    3.1.2. Right-of-Way and Site Acquisition Cost

    Land will be required to accommodate the ROW for the transmission lines and

    associated facilities for the projects. From the review of the preliminary corridors for the

    transmission lines, and due to the fact that the study area is located in a remote region

    of northern Ontario, we have assumed the lands required for the projects will primarilybe “Public Land”. Public (Crown) lands owned by the province and are under the

     jurisdiction of the Ministry of Natural Resources (MNR) with respect to their control and

    management. Under this scenario, the MNR policy for Utility Corridors on Public Lands 

    (Policy 4.10.03, October 2006) is applicable to the projects. This policy provides a

    standardized approach to granting of tenure and establishment and collection of rent for

    the occupation of public land by utility companies. The annual rental formula is based

    on land value per hectare (ha), multiplied by the area occupied, multiplied by impact on

    fee simple (75% for transmission lines and facilities) and multiplied by the annual rate of

    return (8-10 %). For costing purposes we have assumed the following ROW widths for

    the project in the study.

    LINE DESCRIPTION ROW, in meters (typical)

    2-cct 230 kV, lattice towers 40

    1-cct 230 kV, lattice towers 30

    1-cct 230 kV, H-frame wood poles 30

    2-cct 115 kV, lattice towers 30

    1-cct 115 kV, H-frame wood poles 30

    1-cct 115 kV, single wood pole 20

    NOTE: ROW width is a function of span length, line voltage, height of the structures.

    For example using the 1-circuit 230 kV transmission line option from Ignace to PickleLake with a length of 295 Km and assumed ROW width of 30 m, the following cost

    estimate (annual rental) is derived.

    Land – $1,062,000 (1,180 ha x market value of $1,200/ha for northwest Ontario) x 75 %

    (impact on the fee simple) x 10% (established/assumed rate of return by MNR) =

    $79,650 annually or $270 per Km.

    The above formula has also been applied to determine annual rental cost for site

    facilities (e.g., transformer stations).

     Annual rental cost for crown land required for the transmission line project andassociated facilities is presented in Tables 1 thru 4. These costs are not included in the

    total cost or the unit costs per kilometer.

    3. General Engineering Considerations

    •  2011 unit costs for Project Management, Engineering Procurement Management,

    Project Controls, Construction Management, Quality, Safety and Environmentalsupport were provided by the SNC-Lavalin procurement group

    •  All construction activities were estimated per unit cost/activity as per our defined

    Work Breakdown Structure (WBS).•  The cost of tower steelwork is assumed to be $3.00 per kg. This was developed

    from a current 5 year term agreement with an existing supplier and is based upon

    today’s market prices (as with all commodities, current pricing is no guarantee of

    future trends) with the addition of transportation costs.

    •  Allowances were included for stand down due to bad weather.

    •  For transmission line estimates, the base cost has been presented with the cost

    of overhead steel earth wire only and the cost of Power Line Carrier (PLC)

    facilities. Cost for the fibre optic infrastructure required for substation telecom

    requirements is shown separately in the column labeled “Cost of Fibre Optic

    Comms”. This cost includes one 48 fibre OPGW, accessories and repeater

    stations, which is sufficient for substation requirements only. Some spare fibres

    may be available for commercial use, but accessories and repeater stations

    would have to be modified or added to allow for commercial fibre optic

    applications.

    Exclusions:

    For the purposes of this study, the following factors were not included in the estimates:

    •  Disbursements to land owners/occupiers

    •  Type testing and third party quality testing and inspection

    •  Environmental mitigation

    4. Unit Cost Findings, including summarized results as provided in Tables 3, 4, 5

    Development work estimates shown in the applicable cost tables were based on theidentified routes and assumed transformer stations locations for the purpose ofcompleting environmental assessments, securing all environmental permits/approvalsand obtain land tenure for the transmission lines and facilities identified in NorthernOntario and the Far North.

    Single Line Diagrams (SLD) were developed in order to prepare detailed technical datarequired for the estimates. These SLDs were the basis of cost tables 4 and 5, and areincluded in Appendix 3.

    3.1 Unit Cost Findings for Northern Ontario

    The study findings for lines and facilities in Northern Ontario are summarized in the costtables shown below.

     Assumptions used in the development of the estimates are outlined in section 2.Technical details used in the estimates are included in Appendix 2.

    Cost estimates in Northern Ontario are generally higher than in the Southern part of theprovince due to the lesser availability of infrastructure and higher transportation costsfor labour, equipment and material. Whereas construction in Southern Ontario is notusually affected much by winter weather, more severe winter weather in NorthernOntario will reduce productivity. Foundation installations in Southern Ontario aregenerally less costly to work with due to the soil conditions than in Northern Ontariowhere bedrock are frequently found in many parts.

    3.2 Unit Cost Findings for the Far North

    The study findings for lines and facilities in the Far North are summarized in the costtables shown below.

     Assumptions used in the development of the estimates were outlined in section2. Fortechnical details used in the estimates refer to Appendix 2.

    It was expected that cost estimates in the Far North are generally higher than inNorthern Ontario. The Far North generally has limited infrastructure causing significantlyhigher transportation costs for labour, equipment and material. More construction

    access will be required in the Far North adding to the higher cost, or, where not possibledue to muskeg for example, winter construction will be required. Winter constructionhowever, affects productivity to a much higher extent than in Northern Ontario; reduceddaylight reduces work hours as well.

    Foundation installation in the Far North is also expected to be costlier due to permafrostand muskeg conditions.

    5. Supporting Evidence and Benchmarks

    Detailed parameters used in the development of the cost estimates are included in

     Appendix 2.

    Given our extensive exposure to the Transmission and Distribution markets,ongoing work within the province and complimentary relationships within thegeographical study area, we are confident of the basis of the estimates producedwithin the constraints of this submission.

    The cost estimates for Northern Ontario and The Far North are comparable (withinthe constraints of this submission and without breaching commercialconfidentialities) with the following studies by SNC Lavalin:

    •  The Northland Study ( 2011)

    •  The Nishnawabe Aski Development Fund (NADF) Study in Northern Ontario(2009, basis of estimate 2007)

    •  Goldcorp’s Red Lake Project (2011)

     All of the above projects utilized a single circuit 115kV transmission line H-framedesign, although each project, as with almost any transmission project contained

    unique characteristics, such as timing, specifications, access, constructionmethodologies and location.

     APPENDIX 4

    ENVIRONMENTAL ASSESSMENT

    The Ontario Ministry of the Environment (MOE) has developed environmental

    assessment (EA) requirements for electricity projects. These requirements are set out in

    Regulation 116/01 (referred to as the “Electricity Projects Regulation”), made under the

    Environmental Assessment Act  (EAA). In the MOE “Guide to Environmental

     Assessment Requirements for the Electricity Projects” (MOE Guidelines),  the subject

    230 kV transmission line options are considered a Category C type project. Category C

    projects are major projects with known significant environmental effects. These projectsrequire an Individual EA and must be approved by the Minister in accordance with

    subsection 5(1) and 5 (2) of the EAA.

    There is a potential for the 230 kV line options to also "trigger" an environmental

    assessment screening under the Canadian Environmental Assessment Act  (CEAA),

    should a federal authority perform one or more of the following: grant money or any

    other form of financial assistance to the project; lease/sell land; or issue a

    permit/approval. However, for purposes of the cost estimate at this time we have

    excluded any environmental assessment requirements under the CEAA.

    The proposed 115 kV line options fall within the types of projects covered by the “ClassEnvironmental Assessment for Minor Transmission Facilities” (Class EA, Ontario Hydro,

    1992) document, approved under the Ontario Environmental Assessment Act. As such,

    an environmental assessment study is required for the 115 kV transmission lines to be

    conducted in accordance with planning and design process described in the Class EAdocument.

    The identified OPA transformer and distribution stations, and SVC, Statcom or otherfacilities associated with the 115 or 230 kV options to supply Pickle Lake and remote

    northern communities are assumed to be included in the environmental assessment

    process.The 44 kV and 25 kV remote distribution lines do not require completion of an EA.

    However, the work would be subject to numerous permits/approval and licenses from

    regulatory agencies and are assumed to involve the preparation of a natural heritageexisting conditions and impact study to evaluate the routes and to fulfill permitting

    requirements. As well, engagement of remote aboriginal communities on specificrouting options is also assumed to be required.

    Individual Environmental Assessment

    Key work components for the Individual EA required for the 230 kV transmission line

    options, and assumed in the SLI cost estimate, include the following:

     All 230kV transmission lines will require an Individual EA, which is an extensive

    undertaking involving numerous initiatives and requirements.

    Class Environmental Assessment

    The MOE Guidelines stipulate that 115 kV transmission lines and associated facilities(e.g., transformer station) are required to complete an environmental assessment inaccordance with the process set out in the Class Environmental Assessment for MinorTransmission Facilities (Class EA) as approved under the EA Act. Projects subject tothe Class EA are consistent with the screening level assessment process outlined underthe Electricity Projects Regulation (O. Reg. 116/01) for Category B type projects.Typically these types of projects have predictable range of effects, can be readilymitigated and are a proponent-driven self assessment process.

    The scope of the environmental assessment for the 115 kV line options would involvesimilar work components as an Individual EA, however the assessment is assumed to

    be less rigorous and would exclude Step 1 noted above (i.e., preparation of Terms ofReference). In general, the Class EA planning and design process includes thefollowing major steps:

    1. Identify need/justification and purpose;

    2. Collect relevant environmental, social and technical information;

    3. Evaluate and compare site/route alternatives;

    4. Identify and provide project description of the preferred design/solution;

    5. Identify and assess environmental effects, including mitigation and impactmanagement measures to reduce negative environmental effects; and

    6. Preparation of an Environmental Study Report (ESR) to document the EAprocess.

    Consultation with external government agencies, public, Aboriginal communities aremandatory throughout the process.

    The proposed high voltage transmission lines to supply Pickle Lake and 44/25 kVdistribution lines to remote communities will require a number of environmental permits,
