| Summary/Abstract |
A U.S. nation-wide transmission overlay is a high capacity, multi-regional transmission grid, potentially spanning all three interconnections, designed as a single integrated system to provide economic and environmental benefits to the nation. The objective of this paper is to identify benefits to building a national transmission overlay and to lay out essential elements to facilitate continued dialog on this topic. A preliminary study performed on a national scale using a long term investment planning software illustrated that a national transmission overlay, under a high renewable penetration scenario, could result in cost-reduction of between one quarter trillion and one-half trillion dollars over a 40-year period, while promising to increase infrastructure resilience and flexibility.

| Summary/Abstract |
We analyze the electricity transmission planning process in Germany (Netzentwicklungsplan), which separates transmission expansion decisions from generation dispatch. We employ an economic modeling approach to analyze two different network planning settings. In the first setting, there is no trade-off between transmission network development and generation dispatch, as is currently the case in Germany. A second setting alternatively allows for such a trade-off, and thus represents a welfare superior way of transmission network planning. Applications with the two model variants are carried out for the German electricity system in 2035. The results illustrate overinvestment in transmission capacity and decreased welfare associated with the Netzentwicklungsplan.

| Summary/Abstract |
This viewpoint reviews renewable energy development in 14 markets that differ in market structure (restructured vs. not restructured), use of feed-in-tariff (FIT) (yes vs. no), transmission planning (anticipatory vs. reactive), and transmission interconnection cost allocated to a renewable generator (high vs. low). We find that market restructuring is not a primary driver of renewable energy development. Renewable generation has the highest percent of total installed capacity in markets that use a FIT, employ anticipatory transmission planning, and have loads or end-users paying for most, if not all, of the transmission interconnection costs. In contrast, renewable developers have been less successful in markets that do not use a FIT, employ reactive transmission planning, and have generators paying for most, if not all, of the transmission interconnection costs. While these policies can lead to higher penetration of renewable energy in the short run, their high cost to ratepayers can threaten the economic sustainability of renewable energy in the long-run.
