Cost-Competitive With All Power Technologies

247Solar Plants generate power competitively with all other clean power sources today and with traditional power sources tomorrow. Uniquely, they offer a low-risk, financeable, and rapidly-deployable plug-and- play clean power solution with 24/7 operation. When co-deployed with PV and wind installations, they act like batteries, filling in for PV and wind’s intermittency by stabilizing the grid with the quick responsiveness of microturbines to voltage fluctuations and on-demand power. Independently, they offer higher ROI/NPV than PV or wind for projects from 300 kW (~4 acres) to utility scale.

247Solar Plants, which are pre-engineered modules, require minimal custom engineering, using mostly proven components for higher reliability, lower technical risk, and relative ease of project financing. Standardized, mass-produced components allow for rapid site assembly, shorter project cycles and lower component costs over time. 247Solar’s simple air-based system operates at atmospheric pressure and requires no water/steam or molten salts, reducing complexity and lowering CAPEX and O&M costs.

The following table compares overall CAPEX ($US) of a new 1000-megawatt power plant in the US using various power generation technologies, along with Capacity Factors and CAPEX per kilowatt-hour/year. It also compares current and future costs per kWh for each technology, assuming the continuation of current trends: cost increases for coal and nuclear and cost declines for PV and wind.

CAPEX, $Billion Capacity factor, % CAPEX$/kWh/yr Cents/kWh today Cents/kWh future
New Coal 4 65-85 60 9+ 10+
New Nuclear 6 80-90 75 9+ 10+
Photovoltaics 1.7 18-25 95 7 5-6
Wind 2.5 25-35 120 6 5-6
CSP 7 50-75 105 18 9-10
247Solar Plants 4.5 90-100 50 8 5-6

247Solar Plant Costs Decline With Volume

Like PV and wind, 247Solar costs decline with time because all components are mass-produced. In management literature, Cumulative Cost Learning Curves are a well-documented approach to projecting future costs based on doublings of cumulative factory production. For example, when cumulative (not annual) production doubles from say 1,000 units to 2,000 units, costs likely will decline by 90 to 95%, on average.

For example, with every doubling of cumulative installed capacity since 2009, solar PV module prices dropped 12% and the cost of electricity from wind farms dropped 10%, due to economies of scale and technology improvements. 247Solar’s analyses showed that, conservatively, its costs drop by just 7% with every doubling of cumulative installed capacity and, potentially, by as much as 9%. An Engineering and Cost Feasibility Study of the 247Solar Plant concept funded by the US Department of Energy projected that the cost per megawatt of the 247Solar Plant will decline from about $5,500,000 initially to under $3,000,000 ($US) after just 2000 megawatts of production and deployment (roughly two large coal plants). This is shown in the following chart.
