  • The natural gas pipeline is an efficient method to transport gas to large natural gas facilities or to offset residential natural gas use.

  • On-site and local demand for energy (transportation fuels, power, or heat) may not exist

  • Large natural gas facilities are more efficient than onsite facilities.

  • Exporting power can be infeasible due to uncertainties in the electrical interconnection process for small generators.

  • Economically feasible small-scale systems using biogas do not have a good track record for achieving air quality standards in severe non-attainment air districts.
