Utility pricing

With the current energy demands increasing, the unit costs of all utilities are increasing. Any prices quoted need to be reviewed periodically to determine their effect on plant operations. A company utility supervisor is a good source of future price trends. Unfortunately, there are no shortcuts for estimating and projecting utility prices. Utilities are the third largest expense item in the manufacture of a product, behind raw materials and labor. 

All prices are as of mid-1975. Escalation to the end of 1984 requires a factor of 1.8. However, the location of the optimum will be approximately independent of the escalation if it is assumed that equipment and utility prices escalate approximately uniformly so the analysis is made in terms of the 1975 prices. Annual capital cost is 50% of the installed price/year. 

This paper discussed the relative sensitivities of hydrogen cost to capital, feedstock, and utility prices for various different types of production processes, outlines some process selection criteria for different applications, and indicates what changes in process economics might be anticipated from new technical developments. 

Incorporating some or all of the above mentioned improvements will lead to a considerable reduction of energy consumption of an ammonia plant based on steam reforming of natural gas or naphtha. The actual plant design will depend on the project particulars and feed and utility price structure. 

Some smaller plants purchase utilities over the fence from a supplier such as a larger site or a utility company, in which case the utility prices are set by contract and are typically pegged to the price of natural gas or fuel oil. 

A sensitivity analysis was performed to identify the effect of the driving force on the utility cost and the equipment cost. The results are shown in Fig. 4 and they confirm that the driving force is inversely proportional to the ease of separation and therefore the cost. This means that over-prediction of the driving force may lead to infeasible separation while under-prediction of the driving force may lead to waste of resources. The equipment costs were estimated by Aspen ICARUS and utility pricings were based on general pricings in Thailand. 

There may be little economic incentive for the polluter to reduce pollution. Emission charges, disposal fees, and environmental penalties (e.g., fines) may be too low. Market prices of raw materials and utilities seldom account for external costs low prices of inputs reduce the incentive to consume less. The situation can be worsened when governments subsidize raw materials or utilities prices. 

Bureau of Agricultural Economics, Consumption of Food in the United States, Misc. Publ. 691 (1948). Statistics for 1909 to 1948 on food supply and utilization, prices and per capita consumption and on shipments of major food commodities for civilian relief in areas occupied by armed forces. 1949 Supplement gives revisions and 1949 data. No supplemental data since 1949. 

To develop and monitor any aspect of drug policies - which naturally include cost containment - one needs to collect reliable and valid data on processes and outcomes. This chapter focuses on the data needed to detect and evaluate the impact of a drug policy on the different elements of drug management and delivery. Important variables relate to the various aspects of prescribing, dispensing and consumption, but also to the ultimate consequences in terms of health and finance. The types of data discussed in this chapter therefore include facts and hgures on pharmaceutical expenditure, utilization, price, health and economics outcomes, as well as data on the pharmaceutical industry. 

The following notation will be used the price p of the chemical is a function of the total quantity sold, Q, and an index A, representing the reliability of the chemical this index will be referred to as the accumulation constant of the chemical. The inverse demand curve can therefore be written as p(Q, A). Consumers preferences for chemical persistence mean that marginal utility (and hence price) is increasing in the level of this characteristic, up to some critical point A after this point, concerns for toxic residues and personal safety mean that marginal utility/price decreases. Therefore dp/dA = p >OfoiA< A but < 0 for A > A and p < 0. As usual the price of the chemical decreases with the aggregate quantity sold (i.e. dp/dQ= Pq< 0). 

The utilities costs are usually estimated on the basis of mass and heat balances, on the equipment characteristics, and on the utilities prices. The prices of utilities have to be corrected for local conditions and historical trends. The main constraint at this point is the cost of energy because of unstable prices of fuels, which may significantly vary both in the long and short terms. The historical trends are shown in Figure 65.4, where one can see the well-known effects of the Iranian Revolution and the Iran-Iraq War... 

The problem of energy price volatility can be resolved by dividing the utility price into separate terms, each of them being a product of a certain coefficient and the price parameter [34]. The first term reflects the conventional inflation rate while the second one represents the contribution from the fuel price ... 

The OPEX is calculated using utility requirements of the equipment and utility prices based on an annual operating time of 8760 hours [Equation (10.B.3)]. 

Determing the price of a product which is not on the market can be achieved by utilizing price comparison with imported products on a nutrient basis. For multiple nutrient products, new product prices can be determined by calculating the price based on imported component materials. For example, the price of a new multinutrient -produGt-4 -25i -Gan-be-determined as follows ... 

The compensation policies for which this book is pertinent are mostly cash transfers or near cash transfers such as food stamps or heating vouchers. Other compensatory mechanisms, such as lifeline utility pricing for low-volume users or training programs for workers laid off from state enterprise reform, are common elements accompanying such reforms, but are outside the scope of this book.

The first comparison level was based on the energy consumption for the pretreatment methods (Figure 2.10). The utility prices were 6/MMBtu for heating, 4/MMBtu for cooling, and 0.07 kW h for power. After this comparison, the OS option was discarded, because it showed the highest energy demand.
