21 Airports that have identified a problem and a solution and developed the guiding principles behind the solution must next vet the solution and its alternatives to determine that there is a business case for proceeding. As with the methods of science, a theory is proposed and then tested.

Evaluation Criteria and Ranking Methodology 23 However, concentrating solar power is unlikely to be sited on an airport property unless a technological breakthrough is achieved and airport biomass projects are limited in number and scale. Electromagnetic interference has also been identified as producing a potential negative effect on radar although problems have not been documented.

26 Developing a Business Case for Renewable Energy at Airports 3.2.1.2 Availability of Grants An airport's ability to access grants to offset its own total contribution to the project is an important factor in evaluating the pure cost-effectiveness of a renewable energy project. Reducing capital investment will shorten the simple payback period when full project cost recovery can be attained.

Evaluation Criteria and Ranking Methodology 27 The need to invest in reliability and back-up systems has become more evident in recent years relative to the effects of severe storms and international terrorism. Superstorm Sandy was an example of how national investments in population centers along the country's coasts are increasingly becoming more and more vulnerable to severe storms and the potential complexities of sea level rise.

30 Developing a Business Case for Renewable Energy at Airports 3.3.1 Basis and Customization 3.3.1.1 Criteria The matrix includes four criteria that airports can use to evaluate renewable energy projects and their alternatives and generate a score for each project evaluated. • Economic • Self-sustainability • Environmental/Social • Other Economic information provides the critical baseline for any business, including an airport's needs for understanding requirements and sources of financial resources.

Evaluation Criteria and Ranking Methodology 31 • Capital cost leveraging: This factor provides value to options that can attract public and private partners. • Operations and maintenance costs: This factor considers the potential burden the project may place on the airport for system operations and maintenance.
