Technical and Economic Feasibility Studies
Facility Load Profiling
By evaluating all available data (gas and electric bills, equipment power ratings, plant operating characteristics, etc.) Sustainable Automation can develop approximate hourly, weekly, and monthly electric and thermal load profiles for a facility. These are necessary for both the design of a distributed generation system and accurate modeling of its performance. In cases of a highly variable load and/or where insufficient information exists, we have the equipment to measure and record minute-by-minute electric load of village power plants or industrial facilities.
Distributed Generation Project Performance and Economic Modeling
Using computer simulation tools developed at the
National Renewable Energy Laboratory and elsewhere, we model the energy
flows and economic performance of a proposed distributed generation
system in light of the available renewable energy resources and the
measured or estimated loads. The first phase of such a modeling effort
focuses on determining an optimal system architecture and operating
strategy. A second more detailed modeling phase aims to quantify various
measures of performance of the system (e.g. wind energy produced, diesel
fuel consumed, diesel generator run time, generator start/stops, wind
energy dumped, etc.), which are then used to estimate the savings from
reduced fuel consumption and/or reduced utility energy purchases. Whether
for grid-connected industrial and commercial sites, or for off-grid
village and remote industrial sites, we design the optimal hybrid power
system to meet the customer's cost, fuel savings, and environmental
goals. Where possible, excess wind energy and waste heat is captured
to serve a variety of secondary loads, which may include water heating
and chilling, water purification, and ice making.
