This workshop report provides a summary of the ideas that emerged from the Climate Policy Initiative (CPI) Berlin and the Florence School for Regulation informal workshop on 20 October 2011. The report is structured thus: (1) Financing Grid Investments: How can regulatory frameworks provide sufficient incentives, facilitate access, and reduce cost of financing to deliver necessary large-scale grid investments? (2) Aligning European and National Planning: What is the role of the proposed European Union (EU) Infrastructure Package in aligning EU/regional and national network plans? (3) International Cost Allocation and Financial Support: How are costs shared among countries? What lessons can we draw from the existing mechanism to consider for the proposed new approach?
