Computerized control systems have been used in many years to supervise and control power distribution. These systems, which often are referred to as SCADA (Supervisory Control And Data Acquisition) systems, have in recent been more and more interconnected to other systems in recent years. In modern utilities various kinds of data are exchanged between the distribution management systems and the...

In this paper we have examined the scale and cost inefficiency of a sample of Swiss electricity distribution utilities. To do so, we have considered estimation of a stochastic frontier average cost model using the approach suggested by Schmidt and Sickles (1984) for panel data. A translog cost function was estimated using panel data for a sample of 30 municipal utilities over the period 1992-19...

Problem definition: Utility regulators are grappling to devise compensation schemes for customers who sell rooftop solar generation back the grid, balancing environmental interests and financial of utilities, system installers, retail customers. This is difficult: Regulatory changes made in Nevada 2015 protect Nevada’s utility induced SolarCity, market leader systems, suspend local operations. ...

1 INTRODUCTION Electric power utilities have sustained significant damage from lightning. The occurrence of line faults is one result of lightning damage. To prevent it, power utilities adopt various measures of protection from lightning. Transmission line overhead ground wires greatly contribute to a decrease in the number of line faults by preventing direct hits to the power lines. Lightning ...

We analyze the cost-effectiveness of electric utility rate payer–funded programs to promote demand-side management (DSM) and energy efficiency investments. We develop a conceptual model that relates demand growth rates to accumulated average DSM capital per customer and changes in energy prices, income, and weather. We estimate that model using nonlinear least squares for two different utility ...
