13. value propositions
1. Can build in the desert, away from the coast and
residents
Limit emissions at coastal and residential areas
No heat dumping in the sea
Save the fauna and flora
Use coastal land for water production (RO), residents,
and tourism
Create industrial activity in desert
2.No water needed for cooling
Conserving natural resources (water)
Radiator cooling is standard design
3. Can manage multiple daily starts/stops without
impact on maintenance cost / schedule
Allows integration with renewable – solar and wind
4. Can utilize low grade fuel, HFO, natural gas and crude
oil whichever is available
Can use the cheapest fuel available = Cost saving
5. Can operate at high efficiency at part loads
Conserving natural resources (fuel)
Lowering overall emissions
6. Can efficiently absorb hourly variations in power demand
Optimize the use of existing less flexible plants for stable
base load
Lower cost of operating existing power plants
7. Produce water with reverse osmosis
Power and water production no longer interlinked means
higher flexibility for dispatching and maintenance
Reduce total cost of water and power
8. Fuel and Power security for the country
Meet the steady yearly power demand on the housing
sector in matching steps
Can be built as distributed power without lost economies of
scale (USD/kW)
Fast-track construction schedule
Diversification of power supply, lower risk of failure due to
natural events (force majeur)

Five Main Value Propositions – Desert Power Plants
1. Economic benefits *
Net savings of $115 million/yr with 2,500 MW combustion engine plants, NPV is $1.6 billion (25 years)
Reduce domestic fuel consumption by 3-5 trillion Btu per year (2,400 BOE per day)
2. Operational benefits
High efficiency on part load and base load
Unlimited fast starts/stops (no EOH) – no dispatch limitation, improves efficiency of existing plants
Switch between fuels (e.g. low grade fuel, HFO, Natural Gas) online without stopping
3. Environmental benefits
Desert location keeps coastline cities clean for tourism and residential – no heat dumping in the sea
Dry cooling reduces water consumption by ~97% and related CO2 emissions *
Enabler of renewable technologies – integrates efficient back-up power for solar and wind plants
4. National energy security
Distributed power with economies of scale – diversify power supply, low risk of natural force majeure
Maintenance outage has negligible impact on lost power capacity
5. Construction benefits
Modular design enables fast-track construction – 500 MW can be commissioned in 18 months
Meet the steady yearly power demand in the housing sector in matching steps
* Combustion engine plant vs. super-critical steam plant
