Space Weather Workshop 2008

Ben Damsky

slide2

Method:

Assume a model utility is hit

5,000 MW of generation

3,000 employees

3,000,000 population served

1,000,000 in a metropolitan area

slide3

Method:

Consider costs from 2 viewpoints:

The utility

The whole society

slide4

Method:

  • Consider costs for 3 different
  • storm magnitudes:
  • 200A (Moderate)
  • 400A (Large)
  • 800A (Very Large)
slide5

What does it cost

a utility to respond

to a GIC alert?

slide6

Cost to utility of GIC Response

Stop trans maintenance work:

- 50 men @ $50 per hour

- 8 hours of stoppage

Total: $20K per day

slide7

Cost to utility of GIC Response

Use non-economic dispatch:

- 20% of 5,000 MW

- added cost $10/MWHr

Total: $100K per 10 hr

slide8

What does it cost

a utility when a

solar storm hits?

slide9

Moderate Storm (200 A)

Cost to utility

Loss of life to 5 xfrms:

- Each $100K

Total: $500K

slide10

Moderate Storm (200 A)

Cost to utility

slide11

Large Storm (400 A)

Cost to utility

Loss of a GSU:

- Profit $50M

- Depreciation $25M

- Idle workers $4M

- Transformer $1M

Total: $80M

slide13

Very Large Storm (800 A)

Cost to utility

City without power:

- Sales less fuel $794M

- Idle workers $60M

- Transformers $20M

Total: $874M

slide14

What does it cost

society when a very

large solar storm hits?

slide15

“GNP” for a City

US GNP $44,000 annual per capita

- $170 per working day

- Assume 80% lost: $136

- City of 1M people

Total: $136M/day, $680M/week

slide16

Very Large Storm (800 A)

Cost to society

City without power:

- Reduced GNP $8.8B

Wide area outage:

- Reduced GNP $13.6B

Total: $22.4B
