Vibration analysis technology rxtrndrd at Pontl

MPS, Modem Power systenq May 1995, 15, (S), 49, 51,53-54. Discusses investment in advanced vibration analysis systems which is sub- stantial for even medium sized power stations Iike the independently owned Ponti sul Mincio Thermal Power Plant in Italy, but since it is part of a strategy which wiII result in frequency of major overhaul outages being reduced from every two years to three years, the cost should be recovered within a short payback time. The system concerned in this case is the new Ansaldo MONSOR system which extendes the Solar&on 1051 concept to new horizons.

- . The role of energy in the production of manufacturing output has been debated extensively in the literature, particularly its relationship with capi- tal and labour. In an attempt to provide some clarification in this debate, a two-step methodology was used. First, under the assumption of a five- factor production function specification, the authors distinguished between electric and non-electric energy and assessed each component’s rclation- shi with ca ital and labour. Second, the authors calculated both the Allen an B* P pnce e asticities and constructed 95% confidence intervaIs around these values. The authors discuss their conclusions.

Q5lO5456 Assessing demand when lntroduclng a new fuel. Natural gas on Java Van Grocnendaal, W. J. Energy Economic& Apr. 1995.17, (2), 147-161. The Indonesian novcmmcnt is investing in a PBS transmission svstem on Java. For the eviluation of this invcs&ent aTorccast of the dehnd for natural gas by the manufacturing sector is needed. To obtain this forecast the manufacturing sector is dividid into subsectors according to energy use in production processes. On the level of production processes the opportu- nitles for natural gas are based on net present value evaluations of its future benefits in aroduction. This results in the desired fuel mix for manufactur- in4 subscciors, from which the gas intensity ratios per subsector for cxlsting production and new investments are calculated. Gas demand can then be forecast by combinin

(In German) Reports that building services engineers no longer wish to overcome the structural inadcquacres of buildings by the use of large, energy systems working against natural conditions.

95105499 Determinants of program effectiveness: Results of the natlonal weatherlzatlon evaluation Brown, M. A. and Berry, L. G. Energy, Aug. 1995, 20, (8), 729-743. The findings of a national eveluation of the U.S. Department of Energy’s low-inwme Weatherixation Assistance Program (‘Program’ are used to explain variations in Program effectiveness. Overall, the b mgram was found to be a cost-effective federal investment. However, local weatherixa- tion agencies vary greatly in the effectiveness of their o erations, and the energy saved by individual dwellings ranges widely. &e pr demon- strates the value of using alternative but complementary qu itative and quantitative methods to identify determinants of Program effectiveness.
