In early 2018 the International Renewable Energy Agency (IRENA)
reported on the costs of renewable energy up to 2017. These images
show the cost of generation (upper figure: in USD/kW) and
associated LCOES (lower figure: in USD/kWh) for global geothermal
power plants categorised by type and size.
Binary generation technology would be used at Lemont. Binary
plants account for nearly half of all geothermal power installations,
but being individually smaller in capacity, currently total less than
20% of global generation.
Comparison of the results from Rockwater's modelling* with the
global database, shows that Rockwater's projected LCOE and cost
per kW generated are mid-range in the spread of numbers for binary
plants in IRENA's database (see figures), using an FX rate of 0.74.
(Lower FX rates would result in lower costs for Lemont in USD).

Note, this modelling is a theoretical exercise and more constrained, confident
numbers will follow the initial test well.

Upper: The cost per kW generated obtained from high-level modelling by
Rockwater is close to mid-range of the values for binary plants (circled) in
IRENA's (2018) global database.
Lower: The LCOE obtained from high-level modelling by Rockwater is close
to mid-range of the values for binary plants (circled) in IRENA's (2018)
global database. (Rose-coloured background shows the range of costs for
fossil-fuelled power.)
