Multiple choice

What is the levelized cost of electricity (LCOE) for a nuclear power plant?

  1. The average cost of electricity generated over the plant's lifetime

  2. The cost of electricity generated during the plant's first year of operation

  3. The cost of electricity generated during the plant's last year of operation

  4. The cost of electricity generated during the plant's peak operating period
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The levelized cost of electricity (LCOE) for a nuclear power plant is the average cost of electricity generated over the plant's lifetime, taking into account all costs, including capital costs, fuel costs, operation and maintenance costs, and decommissioning costs.

Multiple choice
