CPCN Application Overview

ORDER SOUGHT

  • Set out in Appendix A; reporting requirements similar to other projects;
  • Pursuant to subsection 46(1) of the Utilities Commission Act, BC Hydro filed

its application for the BCUC to grant a CPCN to construct and operate the Ruskin Dam and Powerhouse Upgrade Project (Project);

  • BC Hydro seeks a CPCN on the basis of, amongst other things, the

Authorized Amount. This is also consistent with BC Hydro’s Capital Project Filing Guidelines:

  • The form of the BC Hydro Board of Directors authorization informs the

Application.

Facility Overview

HISTORY OF RUSKIN

  • Dam and Powerhouse Unit 1
  • riginally constructed in 1930;
  • Second and Third Units

constructed in 1938 and 1950;

  • No major refurbishments

have been carried out since

  • riginal construction;
  • Seismic and structural

deficiencies require that extensive investment is required to ensure safety and reliability of Ruskin. Original 1930 Construction

Facility Overview

  • Dependable capacity of 105MW;
  • Average annual energy output of 348 GWh, 88 per cent of which is firm;
  • Located in the Lower Mainland, which accounts for about 70 per cent of BC

Hydro’s Load;

  • With the benefit of the combined storage capacity of the Stave River System

reservoirs, Ruskin is able to provide the following additional benefits:

  • Dispatchability, which can be used to meet peak load requirements and to respond

to short term variations in load or resource balance;

  • On-call reserve support or the ability to reduce output for BC Hydro as it seeks to

integrate increasing amounts of intermittent clean or renewable energy.

  • Provides dependable voltage and local reactive power (VAr) support for the

Lower Mainland 69 kV transmission network and electrical system. BENEFITS PROVIDED BY RUSKIN

Facility Overview

Right Abutment

  • Consists of highly erodible soils;
  • Both seismic and static deficiencies have been identified:
  • Efforts to date to mitigate sand erosion have only been partially successful;
  • Damage to the Right Abutment seepage barrier of could occur at an earthquake

return period of less than 1 in 475 years.

Left Abutment

  • Portion behind the Powerhouse is steep and unstable and could fail following

a major earthquake with a return period of less than 1 in 2,475 years, which is below CDA guidelines for an earth embankment. Spillway Gates

  • Seismic deficiencies in the existing spillway gates, piers, and roadway of the

Dam where cracking of structures could occur with ground motions of 0.12 g (an event with an expected return period of 1 in 100 years). RUSKIN DAM DEFICIENCIES

slide-12
SLIDE 12

11

Facility Overview

  • The Ruskin dam is categorized as “Very High Consequence”, meaning that

the downstream impacts of a dam breach may include loss of life, and significant financial and environmental damage;

  • A seismic event could result in dam or abutment damage. The level and

extent of damage could include dam or abutment failure and uncontrolled release of the reservoir;

  • If Spillway gates or spillway gate piers are damaged in an earthquake, BC

Hydro could lose the ability to pass water during a post-earthquake drawdown

  • r during a MDE, which could lead to overtopping and dam failure;
  • BC Hydro has undertaken a number of actions in recent years to mitigate

dam risk (section 2.3); in particular, an operating restriction was put in place in 2005 to limit the maximum operating level of the reservoir to El 41.4 m (a 1.5 m reduction) which impacts both the environment and public use of the reservoir. RUSKIN DAM – CONSEQUENCES OF FAILURE

slide-13
SLIDE 13

Facility Overview

Deficiencies

  • Powerhouse structure and/or Left Abutment (behind the Powerhouse) do not

meet seismic standards and could collapse in a large earthquake;

  • Major generating components, including the turbines and generators,

exciters, governors and transformers (located between the Powerhouse and Left Abutment) are in poor to unsatisfactory condition;

  • Switchyard, located on the Powerhouse roof is a circa 1930’s design and

does not allow maintenance work to be performed at the switchyard without a full station and transformer line outage, and poses safety risks to worker safety (limits of approach);

  • Third party consultant RW Beck found that the major generating components

“[have] well exceeded [their] expected useful life” and that the performance of the Powerhouse equipment has been declining. CONDITION OF THE POWERHOUSE

slide-14
SLIDE 14

13

Facility Overview

Consequences of Failure

  • Collapse of the Left Abutment or Powerhouse building could result in

injury/death, the loss of generating output from Ruskin, and environmental consequences;

  • A failure in one or more of Ruskin’s three generating units will likely result in

an outage of more than a year with increased costs and could result in environmental impacts;

  • RW Beck found that “there is a high likelihood of a major equipment failure

that could cause personal injury as well as extended outage and result in extensive repair and replacement costs”. CONDITION OF THE POWERHOUSE

slide-15
SLIDE 15

Project Overview

  • The Scope of the Project is to correct dam safety deficiencies and replace or

rehabilitate powerhouse equipment and ancillaries to extend the facility life by at least 50 years;

  • Given the extent of work being undertaken by the Project, BC Hydro has not

currently identified any need to undertake significant future capital expenditures at the Ruskin Facility in the short to medium term. PROJECT OBJECTIVE

LONG-TERM PLANNING

  • Need for Ruskin in Load Resource Balance:
  • F2017 for Firm Energy;
  • F2017 for Dependable Capacity.
  • Need is determined by:
  • Net Load Forecast after Demand Side Management (DSM);
  • Less Existing, Committed and Planned Supply.
  • The Clean Energy Act is a key Input

Load Resource Balance

METHODOLOGY AND CHANGES

  • Methodology for the 2010 Load Forecast is substantially unchanged;
  • Used most recent (2010) Long Term Rate Forecast;
  • Oil & Gas and Mining sector growth;
  • Electric Vehicles (EVs) are included in 2010 Forecast;
  • Adjustment to load projections for DSM / Load Forecast (DSM/LF)

Integration: Resolution of the overlap with the Power Smart Codes and Standards;

  • The need for the project’s firm energy and dependable capacity is

based on the 2010 Load Forecast without the increased load impacts of Electric Vehicles and DSM/Load Forecast double counting.

2010 Load Forecast

TOTAL INTEGRATED GROSS REQUIREMENTS BEFORE DSM AND WITH RATE IMPACTS* – 2010 FORECAST VS. 2008 LTAP EU FORECAST

* Rate Impacts refer to load reductions from forecast electricity rate changes but do not include load reductions from two-tier rate design

  • Between F2008 and F2010, total requirements have declined by approximately 3,500 GWh or 6.0 per cent.
  • Transmission sales have declined by 2,400 GWh or 15.0 per cent over the same time period. This reflects a number of

permanent closures, curtailments and rapid decline in demand for BC’s raw exports. Sector most effected by global slow down includes forestry and mining. Recent trends indicated that commodity prices and demand have stabilized.

  • Current load growth projections reflect agreements reached for Northwest Transmission Line (NTL); and increased

inquiries and nomination for electricity service for mining and oil gas. However these loads can be volatile – up or down.

  • The 2010 Load Forecast includes the impact of EVs (2,100 GWh in F2030) and adjustments for DSM/LF Integration

2010 Load Forecast

INTEGRATED TOTAL PEAK BEFORE DSM AND WITH RATE IMPACTS – 2010 FORECAST VS. 2008 LTAP EU FORECAST

* Forecast excludes Fort Nelson and includes capacity transfers from BC Hydro to other Utilities including Fortis BC, Seattle City Light and the City of New Westminster .

  • Current Peak demand projection is below 2008 forecast in the short term. Reflects historical decline in transmission peak

demand from reduced loads and closures.

  • Middle and long term forecast above 2008 forecast. Reflects anticipated higher peak demand from oil and gas and mining

loads.

  • EV impact reflected in later 10 years of the 2010 Load Forecast. EV peak impact reflects a charging profile that builds up

through the day. Profile based on battery depletion rates and driving patterns and data is supported by EPRI studies.

GENERATING ALTERNATIVES

Project – Retain 3 (recommended alternative): The spillway gates and piers will be replaced. All three generating units replaced/refurbished. Current 41.5m operating restriction is removed. Alternative A – De-Rate 2: The spillway gates would be removed and small (approx 2.5m in height) automated crest gates installed

  • n the Dam crest to provide enough spill capability to ensure that a

plant trip does not dewater the lower Stave River. Only two of the three generating units would be replaced/refurbished. Alternative E – De-Rate 3: As in the Permanent De-Rate Alternative, the spillway gates would be removed and small (approx 2.5 m) automated crest gates installed on the Dam crest. A lower unit 3 intake would be installed. All three generating units and their ancillaries would be replaced/refurbished.

DECOMMISSIONING ALTERNATIVES (NO GENERATION)

Alternative B – Overflow: The spillway gates would be removed and flashboards installed on the crest of the five interior spillway bays. The Powerhouse would be removed down to the generator floor and new discharge valves would be installed in a newly-constructed valve- house where the powerhouse existed. Alternative C – Remove: The Dam would be removed and the Hayward Lake Reservoir would be returned, to the extent practicable, to its original condition. The Powerhouse would be removed to the generator floor, and all three penstocks would be filled with gravel and capped with concrete at both ends, as would all three draft tubes. This alternative would require dewatering Hayward Lake Reservoir prior to removal of the Dam. Alternative D – Tunnel: This alternative is similar to the abandonment with dam removal; rather than removing the Dam, a large opening would be excavated through the base of the Dam to allow water passage.

SUMMARY

  • The Project is the highest capital cost option. The lowest capital cost

alternative is abandonment of the Powerhouse with overflow of the existing dam (Alternative B);

  • When compared with the alternatives, the Project (upgrade of all three units)

provides:

  • The highest net present value;
  • The greatest energy and capacity benefits; and
  • A competitive unit energy cost.
  • The next best alternative is Alternative A (Upgrade only 2 units and lower

Schedule and Environmental Risks

SCHEDULE RISK Three key schedule delay risks during construction: 1. Excavation work, and materials challenges; 2. Adverse weather; and 3. Inflow conditions. ENVIRONMENTAL RISK Two key areas of environmental risk include:

  • 1. The potential for a significant spill to maintain flow continuity; and
  • 2. The potential for loss of flow continuity.

Schedule and Environmental Risks

SCHEDULING AND ENVIRONMENTAL RISK MITIGATION In addition to implementing contract and project management best practices, the Project has been sequenced as follows to minimize scheduling and environmental flow-related risks:

  • 1. The generating unit replacements will take place sequentially one unit at a

time, allowing greater work area to the contractors and mitigating environmental downstream flow continuity and spill risk by leaving two generating units available for service to mitigate the risk impact of an unplanned generating unit outage.

  • 2. Work that requires a reservoir drawdown is scheduled to occur during the

Fraser River freshet so that tailwater elevations can be maintained downstream from the Dam for fish habitat in the event of a forced unit outage at the Ruskin Facility.

  • 3. The Right Abutment work is being performed first as it represents the highest

risk exposure for this project.

Project Cost Risk

KEY CONTRIBUTORS TO COST RISK

  • Project involves the replacement of equipment within an existing facility, with

limited working space, that will be operating, resulting in a higher level of cost uncertainty;

  • Project scope and schedule adjustments during construction, and market

interest have the greatest potential to affect the overall cost of the Project. MITIGATION OF COST RISK

  • Scheduling strategy described earlier;
  • Cost risk has been mitigated through:
  • Clearly defining scope of Project;
  • Contingencies to accommodate unknown risks;
  • Management reserve for FX and market condition-driven price increases;
  • Third party due diligence review of cost estimate;
  • Development of a procurement strategy incorporating such elements as

constructability reviews, early contractor involvement, and experienced BC Hydro Project staff.
