10 respondents provided a breakdown of the proportion of the HRSGs they supply (by value) in each of 6 size categories. The averaged information is shown below:- Figure 36: Average percentage of business by HRSG size. This simply shows that there is activity at all scales. It is based on a simple average of the percentage of units (by value) that each company supplies. Since the companies that supply the larger units also have far larger turnover, in value terms the market is dominated by the large units. 6.3 Market Perception amongst Consultees Consultees in the US suggest that the market for utility scale HRSGs is very poor currently. Prior to the last year or so, the market in the US was buoyant. HRSG companies had expanded to meet a demand for new utility scale power plant. However the market is now largely saturated and there is generation over-capacity. Transmission and distribution networks are close to full capacity and finance for merchant plant cannot be obtained in the current economic climate. Siemens [10] expect the US HRSG market to slump considerably over the next few years. Consolidation amongst HRSG companies in the US is expected. At the industrial scale there is more activity. There are opportunities for the development of CHP schemes on industrial sites, largely driven by security of price and supply issues in the volatile deregulated electricity market. Concern over climate change is not yet perceived as a significant influence on policy or the market in the US. However, the Clean Air Act is having an influence at the industrial scale. Consents are specifying lower NOx emission levels and rather than retrofitting low NOx boilers and selective catalytic reduction (SCR) some companies are opting to switch to a completely new CHP scheme. One consultee identified Russia as a good current market due to the need to replace ageing and inefficient plant. The same is true of Central and Eastern (104)
European (CEE) countries. The market in CEE countries is likely to be enhanced as the EU enlarges as trade with them will become easier and they will be striving to meet EU environmental standards. Turkey was identified as a good market due to low gas prices and a large demand for electricity. The Middle East was identified as a market with good potential due to the abundance of open cycle gas turbine plant that could be retrofitted with HRSGs for improved efficiency by operating in combined cycle mode or for power augmentation by turbine inlet chilling. One consultee identified Italy and Spain as good markets for oil replacement plant and the Middle East for desalination plant. The market in China is expanding rapidly, but is viewed as a difficult place to do business. This is due to the bureaucracy of complying with the local codes and standards and the fierce competition from local manufacturers. The market in Indonesia is also apparently growing, but competition from Chinese manufacturers is stiff here too. A number of other markets were identified by consultees as still being active, despite the general depression of the CHP market throughout Europe associated with falling electricity prices and rising gas prices. Within Europe the markets in France, Spain, Italy, Germany and Scandinavia are perceived as being most active for the development of CHP projects. German and Scandinavian markets are seen as being more highly regulated still (less competitive pressure on wholesale electricity prices) and there is price support for CHP schemes in Germany for a limited period. Some new CHP schemes in Germany benefit from a guaranteed feed in price. France, Spain and Italy also have support mechanisms in place for CHP. 6.4 UK Market The UK electricity generator market has essentially two sub-sectors, utility CCGT / CHP and industrial CHP as outlined in Table 8. Utility CCGT/CHP Industrial CHP DISTRIBUTION BY MWe +1 MWe +10 MWe +40 MWe +500 MWe 60 20 200 80 20 Table 8: UK power generation market sectors. Utility CCGT/CHP are required to compete with conventional plant under the New Electricity Trading Arrangements (NETA). Industrial CHP plants are struggling under NETA trading conditions and most are currently operating their steam and power supply contracts at a loss. There is therefore a degree of turmoil within the market with attrition expected amongst some of the players. However despite competition problems both sectors cannot ignore the need to consider widespread integrity and performance improvements to meet NETA market and client contractual demands. (105)
