Research Objectives and Requirements
Understand individual and combined life-cycle benefits of co-siting.
Document successful and unsuccessful co-siting case studies.
Develop a decision tool

Proposed Approach and Collection Methods
Develop seven potential scenarios Develop a questionnaire covering the scenarios Contact partners to identify potential case studies Conduct an internet search for potential case studies Contact owners and engineers for co-siting facilities, and obtain information for survey. Use case studies to develop model.
