Arid build Power Plant
Inland area arid / or far from residentiel area Onshore build RO / Decentrilized RO`s
value propositions 1. Can build in the desert, away from the coast and residents Limit emissions at coastal and residential areasNo heat dumping in the seaSave the fauna and floraUse coastal land for water production (RO), residents, and tourismCreate industrial activity in desert
2.No water needed for coolingConserving natural resources (water)Radiator cooling is standard design
3. Can manage multiple daily starts/stops without impact on maintenance cost / scheduleAllows integration with renewable – solar and wind
4. Can utilize low grade fuel, HFO, natural gas and crude oil whichever is availableCan use the cheapest fuel available = Cost saving
5. Can operate at high efficiency at part loadsConserving natural resources (fuel) Lowering overall emissions
6. Can efficiently absorb hourly variations in power demandOptimize the use of existing less flexible plants for stable
base loadLower cost of operating existing power plants
7. Produce water with reverse osmosisPower and water production no longer interlinked means
higher flexibility for dispatching and maintenanceReduce total cost of water and power
8. Fuel and Power security for the countryMeet the steady yearly power demand on the housing
sector in matching stepsCan be built as distributed power without lost economies of
scale (USD/kW)Fast-track construction scheduleDiversification of power supply, lower risk of failure due to
natural events (force majeur)

Five Main Value Propositions – Desert Power Plants1. 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 benefitsHigh efficiency on part load and base loadUnlimited fast starts/stops (no EOH) – no dispatch limitation, improves efficiency of existing plantsSwitch between fuels (e.g. low grade fuel, HFO, Natural Gas) online without stopping
3. Environmental benefitsDesert location keeps coastline cities clean for tourism and residential – no heat dumping
in the seaDry 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 securityDistributed power with economies of scale – diversify power supply, low risk of natural force majeureMaintenance outage has negligible impact on lost power capacity
5. Construction benefits Modular design enables fast-track construction – 500 MW can be commissioned in 18
monthsMeet the steady yearly power demand in the housing sector in matching steps
* Combustion engine plant vs. super-critical steam plant
