Muskrat Falls HVac/HVdc Project Components

• Two 315 kilovolt High Voltage alternating current (HVac)

transmission lines between Muskrat Falls & Churchill Falls (Labrador Transmission Assets)

• 1,100 km High Voltage direct current (HVdc) transmission line

between Muskrat Falls & Soldiers Pond near St. John’s (Labrador-Island Transmission Link)

• Strait of Belle Isle Marine Cable Crossing (3 X 30 km long

cables)

5

AC Transmission: Muskrat to Churchill Falls

• Clearing for right-of-way complete

– 250 km – Clearing: 2,450 hectares

• Towers and foundations

– 1,250 Towers – 8,125 foundations

• Conductors and Fiber Optic cables

– 2-315 Kv, 3 phase conductors – Fiber Optic Cable – Approx. 40% complete

• Work will be substantially

complete in 2015

DC Transmission: Labrador-Island Link

• Clearing for right-of-way ongoing across

province

– 1,100 km – ROW Clearing – 6,554 ha

• Towers and foundations

– First tower erected in Labrador in April 2015 – 1,760 Towers (Labrador) – 2,225 Towers (Island) – Tower erection ongoing in Labrador; start

tower assembly on island in October 2015

Strait of Belle Isle Marine Cable Crossing

• First land cables installed in Shoal Cove, Sept. 2015
• Marine cable manufacturing underway in Japan; last
• f three cables expected in September each 30 kms.

in length

• Successfully completed horizontal directional drilling

(HDD) program; longest landfall application in world

• On track for marine cable installation across the

Strait next year

Environmental Management System

Integration of EMS into Project Execution – All Components

• Design Requirements
• Technical Specifications
• Procurement Packages
• Bidder Evaluation
• Kick-Off Meeting Support
• Weekly Reports to

Stakeholders

• On-Going Field Monitoring
• Use of Powerline by all

stakeholders

16

Collaborative Regulatory Framework

• Blanket Permits

– Water crossings (>1900) – Quarries (>500) – Historic resources – Vegetation clearing

• Proactive Reporting

– Online reporting – Powerline updated constantly – Weekly report to all regulators

• Monitoring Tools

– Electronic forms (iPad) – Real-time field reports and

constraint monitoring

17

HVac/HVdc Construction Monitoring

• Dedicated on-site environmental monitors at each work front
• Real-time access to all EMS components via satellite and

internet connections

• All monitors use an interactive prontoform database and iPad

that provide inspection forms and direct connection to Powerline and the project office

• Dedicated environmental permit coordinators, engineers and

planners

18

Real-Time Internet Reporting

• Pre-set Prontoform templates
• GIS / GPS Mapping functions
• Real-time photograph

transfers

• Immediate distribution to

project office coordinators and engineers

• Field (Camp) access to

Powerline database and constraint mapping

Environmental Effects Monitoring Program

• Purpose is to monitor the overall project

effects and to confirm the predictions of EA and fulfill EA commitments

• LCP has implemented more than 15

comprehensive environmental effects monitoring programs

• Key programs include:

–

RWM caribou

–

MM caribou

–

Newfoundland marten

–

Newfoundland caribou

–

Avifauna
