We broaden the theoretical basis for generating scenario trees in multi-stage stochastic programming based on stability analysis. Numerical experience for constructing trees of demand and price scenarios in electricity portfolio management of a municipal power utility is also provided.

To date limited work has focused on assessing the economic viability of scCO2 extraction to obtain waxes as part of a biorefinery. This work estimates the economic costs for wax extraction from maize stover. The cost of manufacture (COM) for maize stover wax extraction was found to be € 88.89 per kg of wax, with the fixed capital investment (FCI) and utility costs (CUT) contributing significant...

The traditional problem often called “electricity development” is to improve and expand services from an established monopolistic electricity supplier. The lack of an effective dominant utility, however, is a defining condition for the 1.4 billion people without access for electricity, the so-called unserved. Therefore, the issues that arise are different from those of traditional utility servi...

The deployment of smart metering in the electricity industry has opened up the opportunity for real-time BI-enabled innovative business applications, such as demand response. Taking a holistic view of BI, this study introduced a visual data mining driven application in order to exemplify the potentials of real-time BI to the electricity businesses. The empirical findings indicate that such an a...

Under conventional models, subsidizing energy efficiency requires electricity to be priced below marginal cost. Its benefits increase when electricity prices increase to finance the subsidy. With high prices, subsidies are counterproductive unless consumers fail to make efficiency investments when private benefits exceed costs. If the gain from adopting efficiency is only reduced electricity sp...

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...

The residential demand for electricity, studied on the national level for many years, is here investigated on the regional level. A survey of the literature is first presented outlining past econometric work in the field of electrical energy demand. An econometric model is then presented using a 1970 cross-section of sixty-seven New England electric utilities and their service areas as the data...
