There are many potential causes of these issues. Obviously the installations must be part of a suitable maintenance program. But regardless of maintenance there are fundamental installation factors that must be considered for each installation. Common issues seen with process analyser installations that cause problems are:
| The Process AnalyserProcess analysers (or analyzers) are these days considered essential for modern plant closed loop control, for fiscal metering and to optimize laboratory sampling frequencies. Process analysers are expensive, with installed costs ranging from $20,000 for simple pH analysers, up to $10,000,000 for complex NMR analyser systems. After this making such an investment, you want your analyser to function well over its lifetime, reliably producing the intended data stream for operations, billing, and quality control.  © akiyoko / Fotolia Process Analyser TroubleshootingProcess analyser troubleshooting can be a difficult task. WAPGC have personnel with successful experience in design, installation and maintenance of process analysers at several Australian/Asian hydrocarbon processing installations. WAPGC personnel have experience with the following process analysers; Gas Chromatograph (GC), Density, IR, Distillation, Viscosity, PH, Flash Point, Cloud Point, Freeze Point, NIR, NMR. WAPGC can assist you with the identification and rectification of your process analyser issues.

N+1 and N+2 are terms commonly seen when describing a power station planting. So what do these terms mean? Disclaimer: Firstly, it is important to note that the meaning of these terms are often defined in contracts, so they can have different meanings from contract to contract. The meanings of the terms presented here are of a general nature. For the purpose of this discussion, we will ignore the effect of large motor drive starting loads or other special circumstances that might impact selection of generator sizing or the number installed. Where is it used? The term “N+1” applies to off-grid or remote power stations such as power stations that supply remote towns or mines which are not connected to the power grid or any other power station. The term doesn’t make a lot of sense in the context of a grid connected power station. This will become apparent in the discussion below.  How many generators to install? N, N+1, N+2 ?
 OPERATIONAL READINESS Operational Readiness is about ensuring that an asset is in a condition that is acceptable for the Operations group to take over, and that the appropriate documentation, training and operational resources are available. The asset might be a new asset, or it might be an enhanced asset being returned to operation following an upgrade or Turnaround. Agree The Roles Early... Roles and responsibilities need to be defined - preferably early in the delivery of a project. The key stakeholders in this process are the project delivery group, operations, and the maintenance group. How the operational readiness roles are attributed will depend on the agreed processes and division of responsibilities within an organisation. 
Operations, as the owner of the plant once handed over, can also have the role of registering classified plant and carrying out other activities required by Regulations.  Have an Operational Readiness Plan... The key to effective Operational Readiness is to have a plan. The Operational Readiness Plan should be tailored to suit the complexity of the project. It is preferable that the Operational Readiness Plan is developed early in the project. This will help:

Why did the Electricity Balancing Price fall in 2014?Looking at the daily average balancing prices for 2014 shows an interesting change mid year. The chart below shows the daily average balancing prices for year 2014. These are the blue columns. Each is the simple average of the 48 half hour trading period balancing prices for each day. Overlaid on the chart are 7 day and 30 day moving averages of the daily average data. 
2014 IMOWA Balancing Prices
[Chart based on raw data sourced from IMOWA.COM.AU] Why the fall in balancing price?The 30 day moving average shows a distinct change in average balancing price from around $60/MWh in the first half of the year, to about $40/MWh in the second half of the year - a fall of around $20/MWh. So what happened? On 1-July- 2014 the carbon tax was repealed. The carbon intensity of the single largest generating organisation on the SWIS is approximately 0.9 tonne CO2/MWh, and the carbon tax was approximately $23/tonne, which works out to a cost of around $21/MWh. This matches the fall in balancing prices which occurred around July 2014. Mystery solved. Energy ConsultingWA Power & Gas Consulting is a firm of Energy Consultants in Perth WA.

South West Interconnected System - Demand (MW) Chart based on raw data sourced from www.imowa.com.au Dispatch ObservationsNatural gas fired generation plant picked up the lion's share of the peak, and we can see that some diesel generation was dispatched as well. The contribution from wind power plant on the system fell during the height of the peak demand. Disclaimer
