| 09-04 | Planning, Markets and Investment in the Electric Supply Industry
On March 7, 2008, an executive forum conducted by PSERC, focused on the role and structure of the planning needed to elicit needed investment in the power system. The participants, some 23 senior electricity industry managers, were divided into five groups. Each group was composed of individuals from organizations deemed to have similar institutional, economic and geographic circumstances. This report summarizes the discussions among these groups.

| 09-05 | Characterization of Composite Cores for High Temperature-Low Sag (HTLS) Conductors
New conductors that employ high strength light weight composite cores are being introduced in the electric power system to address the complex problems associated with increasing electric power transmitted with minimal new construction in existing right-of-ways. Two of these conductors are: aluminum carbon composite conductors (ACCC) and aluminum conductor composite reinforced (ACCR) conductors. The ACCR conductor uses a metal matrix core and the ACCC conductor uses a carbon composite core. Composite cores have a higher strength and lower coefficient of thermal expansion when compared with the steel core used in traditional aluminum conductor steel reinforced (ACSR) conductors. The effect of the temperature distribution on the current carrying capacity of these conductors is not known. The objective of this study is to model the radial temperature distribution and its effect on current carrying capacity in bare overhead ACCC and ACCR conductors. This study develops a method to calculate the radial temperature distribution in composite (ACCC & ACCR) conductors.

| 09-09 | Facilitating Environmental Initiatives While Maintaining Efficient Markets and Electric System Reliability
Emerging environmental policies to reduce CO2 emissions will raise a number of challenges for the electric power industry as it continues to maintain a reasonably priced and reliable supply of electricity. Careful analysis of the implications of those environmental policies is warranted because of the effects they could have on retail prices, on the system-wide cost of operation, on reliability, and on emissions of all pollutants. This study focused on a particular environmental policy: cap-and-trade. We used an economic/engineering model of the power system in the northeastern United States as the conceptual framework for analyzing the impact of environmental regulation of CO2. In our study, we conducted simulations using a 2007 power system with network reduction to capture both power flows and voltage constraints, thereby enabling 'stress testing' of the current power system. Our analyses led to a number of conclusions about the effects of cap-and-trade policy on the electric power industry.
