Strategic environmental assessment best practices process elements and outcomes in the international electricity sector

This paper examines the contribution of SEA in six international electricity sector planning case studies. All cases showed some "best practice" evidence such as participation, alternatives consideration and impact assessment; however, considerable variability was found in the types of alternatives considered and the approach to impact assessment and monitoring depending on the timing of SEA application in the PPP process. Regarding substantive contributions, SEA was identified by stakeholders as improving communication during planning and informing lower-level decision making, but fared less well in influencing the nature of the PPP at hand; only two cases clearly incorporated SEA recommendations into the final PPP. Overall, results show considerable potential for SEA to support PPP assessment and decision making in the electricity sector, but also a considerable need for improvements in understanding of the importance of the timing of SEA in the PPP process and how to integrate the results of SEA into PPP development.
