Quality Power Management (QPM) and Singapore Turf Club(STC) introduces a newly implemented power managementsolution. This new power management solution focuses onsystem integration to reduce the cost of STC’s power supplybills, and also maximizes the potential of existing powergenerators in STC’s backup system that are currently underutilized.

Singapore Turf Club

Singapore Turf Club (STC) is Singapore’s only racecourseoperator. Located in Kranji, its operations cover a land area of81.2 hectares, housing state-of-the-art facilities and supportingservices dedicated to horse-racing. This includes over 400betting windows with ACCESS terminal points, an auditoriumwith a 100 people capacity, 450 video screens, closed circuittelevision monitors, electronic dividend boards, multi-usefunction rooms and F&B facilities.

An immense amount of power is required to sustain STC’soperation and the load is shouldered by a few incomers fromPowerGrid. Power is distributed using various broken ringnetwork configurations, via several substations located withinthe racecourse. Strategically placed network cuts in the ringnetworks enhance the reliability of the system.

The Floodlighting System

The web of floodlights that illuminate the racecourse groundsis fundamental to STC’s operation. In all, there areapproximately 2,500 track floodlight bulbs installed on theroof of the grandstand, camera towers and 42 high-mastsaround the racetrack for night racing. The existing trackfloodlighting system is powered by a number of 22kV / 400Vsubstations (See Figure 1).

70% of the track floodlighting system is connected to thenormal switchboards, while the remaining 30% is connected to the emergency supply switchboards. The emergency supplyswitchboard is backed up by standby generators andUninterruptible Power Supply (UPS).

In a normal power supply failure condition, the UPS will beable to support up to 30% of the track floodlighting systemrequirements for a short duration, during which the standbygenerators will auto-start and take over to supply the powerneeded. When generator mode is activated, the UPS batterieswill be charged simultaneously.

Measures are in place to minimise any occurrence of majorpower outages but blackouts are always a possibility. With thefloodlighting system being a critical installation for the STC,backup plans over and above the existing system are crucial.

Situation Analysis

As PowerGrid’s supply has been consistently reliable, STCfound that it was under utilising their fully installed powerbackup system that is always on standby to be activatedshould PowerGrid’s supply discontinue.

STC’s monthly load profile fluctuates - from 25% on non racedays to 100% during night races - of the declared contractedcapacity. During night racing (scheduled for three Fridays permonth), the demand may shoot up to 100%. However, themaximum demand drops to 60% during day racing (onSaturdays and Sundays) and 25% during non-race days(weekday office hours).

The large number of floodlights consumes an enormousamount of energy. STC therefore has to look at a more cost-efficient way to power up its operation’s critical electricalsystem. In doing so, it could lower its Total Operating Costs(TOC).

QPM was thus brought in to develop an understanding of theenergy consumption and operational requirements of STC.

Recommendation

With the assistance of STC, QPM analysed and proposedseveral possible alternatives to provide reliable power to thetrack floodlights, before deriving at a solution for the mosteconomical means to power up the track floodlights.

QPM recommended the Peak Shaving technique. Instead ofreceiving electricity supply from PowerGrid with standbygenerator sets as a backup source, QPM suggested that STCreverse this operation by using its existing generator sets asthe primary source.

The existing generator sets will be used to supply power to30% of the track floodlights and essential loads, with backupby power supply from PowerGrid. This method will enableexisting standby generator sets to be utilised and cost savingscan thus be achieved. However, the existing AutomaticTransfer Switch (ATS) had to be modified to cater for thisoperation.

With this approach, 30% of floodlights that are connected tothe emergency supply will be powered by the existinggenerators.

As for the remaining 70%, STC could choose to implementthe same method, though an investment will have to be madefor additional generators as the existing generators can onlypower up to 30% of the floodlight load requirements.

There are a few types of generators to choose from, but motor-generator (MG) type generator sets are most suited becausethey do not need UPS as a back up during the transitionperiod, thus eliminating the cost of maintaining UPS.

However, QPM suggests that the existing UPS system beremoved only if the existing generators are replaced with MGtype generators.

Recommendation Rationale

By using existing generator sets as a primary source, STC willbe able to save on its monthly contracted capacity charge,while concurrently receiving reliable supply from PowerGridas a secondary source.

With MG type generator sets installed, the racecourse willgenerate further savings by reducing maintenance costs on theUPS. This capital investment could be moderated by utilizingexisting generator sets first, with the implementation of thevarious portions in stages. A risk comparison of differentpossibilities of power failure is tabulated as shown in Table 1for the implementation stages.

Table 1: Risk Comparison of failures between Present System and Proposed Modifications to the system

Proposed Implementation

The existing 30% of the track floodlighting system connectedto the emergency switchboards are powered using existinggenerators as the primary source (as shown in Figure 2).

Auto-Transfer Switch (ATS) is used to switch the supplyfrom the primary source to the secondary source. Thefloodlights are supported by the existing UPS system to ensurea smooth switch over in the event of a power interruption.

The new generator system will be classified into two differentmodes of operation: “Normal Mode” and “Race Mode” (seeFigure 3). During normal operations, the track floodlightingsystem will be in “Normal Mode”.

During night racing, the mode of operation will be switched to“Race Mode” operation.

Under “Normal Mode”, the track floodlighting system utilisespower from PowerGrid as the primary source. The ATS willbe programmed to monitor the power supply from PowerGrid.If the automatic main failure detects no power from

PowerGrid, it will start up STC’s generator sets andautomatically switch over to this secondary source.

Under “Race Mode”, the track floodlighting system will bepowered by STC’s own generator sets as the primary source.The ATS is programmed to monitor the power source from thegenerator sets, and if it detects no transmission of power, itwill automatically switch over to the secondary source – nowPowerGrid.

A trial run was done to confirm the feasibility of theimplementation. The supply to the emergency boards wasswitched over with the generators as the primary source andPowerGrid as secondary. The trial successfully confirmed thatthe generators are able to support all loads connected to theemergency switchboards.

Data collected from the trial as well as from PowerGrid on theenergy consumed was collated and analysed. Based on thefindings, QPM recommended that implementation becompleted in stages (one substation at a time).

Business Benefits

The proposed new system will run on existing generators and UPS system, which involves little capital investment, except for the cost of modifying the operational function of theexisting ATS as required. This investment cost is basically thelabour cost and the material cost, which is about $1,000 pergenerator set. This covers the cost of both local and remotecontrol by the Building Automation System (BAS).

Should the implementation be carried out in its entirety, STCexpects to see an immediate saving of approximately 3% of itsmonthly electricity bill as seen in the calculations in Table 2.This is clearly plotted in the pie-charts as shown in Figure 4.The investment needed to modify this system will be minimalwith barely noticeable changes to the way the system isoperating.

Analysis based on the following assumptions:

- Total rating of standby generatorsets

2,000 kW

- Standby generator sets operationsper night race in hours

5 hours

- Number of night race per month 3 night race - Cost of operating the standby

generator sets (include fuel and maintenance)

S$0.20 / kWh

- Cost of electricity consumption S$0.12 / kWh - Cost of Contracted Capacity S$7.04 / kW

Before Implementation

(Using PowerGrid Source without generator sets)

- Monthly Contracted Capacity Fee(based on the total rating of generator sets, 2,000 kW)

2,000kW x S$7.04 = S$ 14,080.00

- Monthly electricity consumptioncost (with reference to the electricityconsumption from the standbygenerator sets)

2,000kW x 5 hours x 3 nights x S$0.12= S$3,600.00

Total S$17,680.00

After Implementation

(Using generator sets)

- Monthly cost of operating thestandby generator sets (inclusive of fuel and maintenance cost)

2,000kW x 5 hours x 3 nights x S$0.20= S$ 6,000.00

Total S$6,000.00

Saving

- Saving per month S$17,680.00– S$ 6,000.00 = S$ 11, 680.00

Table 2: Analysis of cost saving

STC has currently implemented the recommendation in one ofits substations with immediate savings of about 1% of themonthly bills.

The projected 3% savings will be achieved once the othersubstations implement this Peak Shaving technique of utilisingthe existing standby generator sets during night racing.

Conclusion

STC is confident of achieving the savings as stated based onall the cost saving data collated for the past one year on thedesignated generator. The engineering team is now lookinginto further savings by operating some of the air conditioningchillers on the generators during race days. By alternating theroles of STC’s own generators and PowerGrid’s supply, STCwill be able to achieve even greater savings than the projected3% from its monthly electric bills. This is accomplished bymaking use of under utilised investments that STC has alreadymade in its backup generators. The cost of implementing thisnew system is negligible compared to the overall savings andeffective use of its existing equipment.
