Title:  The economics of solar PV in Singapore

Solar photovoltaics (PV) has reached the so-called “grid parity” for many commercial and industrial buildings in Singapore. This means that the levelised cost of electricity (LCOE) over the lifetime of the solar system are equal of lower than typical electricity supply contracts. This presentation provides details of the LCOE calculations and its main influencing factors. It will also give an overview of the current status of PV in Singapore and the market outlook in the future. Different business models will be introduced, ranging from self-ownership of the PV system to “solar leasing” and the sale of “renewable energy certificates” to third parties, which would like to use green electricity, but do not have own roof space available.

Title: Energy Saving Ice Condensation Vacuum System at  Refinery Plant

Deodorization is a process to remove unwanted Free Fatty Acids (FFA) from edible oils. Steam is introduced in the deodorizer columns to strip the FFA from the edible oils. The FFA and stripping steam are then removed from the columns using a vacuum system. The conventional vacuum system which comprised numerous large and small steam ejectors, consumed a large amount of steam. To reduce steam consumption, Fuji Oil replaced the conventional system with an ice condensation vacuum system. This new system comprised an ammonia compressor and small steam ejectors. The increase in electricity consumption of the new system was offset by a larger decrease in steam consumption, leading to an overall reduction in energy consumption.

His achievements include heading the start of a Safety, Health & Environment department in Nestle’s Jurong Factory and extending the coverage of SHE to cover the whole of Nestle Singapore.

Title: Waste heat recovery from boiler flue gas by installing condensing economiser for Loos boiler

15t/h of steam was produced from Nestlé’s natural gas fired boiler which had a design feed water proportion of 20% condensate return and 80% make-up water from softener. Prior to project implementation, make-up soft water was supplied to the deaerator at 31°C and further heated in the deaerator using steam while boiler flue gas was discharged to the atmosphere at about 120°C.

To improve energy efficiency, Nestlé installed a condensing economizer to recover both sensible and latent heat from the flue gas to preheat the make-up soft water before it entered the deaerator. The soft water supply temperature increased from 31°C to 60°C, thereby reducing the amount of steam required to heat the soft water in the deaerator. Flue gas temperature was discharged to the atmosphere at about 75°C.

Title: Continuous improvements through Retro-commissioning, real time monitoring, data analytics and performance contracting- Case Study at DCP Sentosa

Owners and service providers often neglect the opportunities for further enhancement of existing equipment through continuous improvement once the pre-agreed goals are met.

Clients not embarking on continuous improvement journey further run the risk of system performance deterioration over time.

The opportunities can only be realized if the owners and service providers have collaborative mindset and are equipped with right skills, technology and information.

Prior to starting this project, DCP had invested in latest hardware and undergone one round of optimization by an ESCO. Nevertheless, DCP is constantly evaluating new opportunities to reduce its energy consumption and environmental impact. After evaluating similar technologies, DCP selected Central Chiller Plant optimization solution from BBP due to level of savings guaranteed through highly intelligent algorithm proposed and are fail safe type, many check & balance ensure reliability of continuous improvement, the track record of successful energy efficiency improvements. DCP and BBP team worked closely to customize and install the BBP solution, keeping in mind the critical operation of a District Cooling Plant.

The impact of embarking on continues improvement journey speak for itself- greater than 8% improvementin energy efficiency leading to 5,500,000 kWh in annual energy savings.

Improving system efficiency is the first step of continuous improvement of the system. BBP and DCP worked together supported by data driven technologies such as continuous remote monitoring with clear KPIs, Alarm and Reports to analyze and undertake timely corrective action to maintain the system efficiently.

The sustained actions together with Advanced Data Analytic of operational data helped the combined team to sustain and improve the performance over a two-year period as well as to identify further opportunities

Deputy General Manager, PacificLight Power

Mr Kwong is the Deputy General Manager of Maintenance at PacificLight Power Station located on Jurong Island. He is a Singapore Certified Energy Manager and Water Efficiency Manager. Mr Kwong has been involved in implementing a number of energy saving initiatives. PacificLight Power is among the most efficiently operated plant in Singapore.

Title: Experience in energy management at PacificLight power station

The operating regime in power sector put emphasis on grid resilience and supply reliability. Operating in an over-capacitated competitive landscape, PacificLight constantly looks for innovative ways to improve reliability, increase efficiency and reduce carbon footprint. The management set 5-year improvement targets and the KPIs are included in the annual appraisal performance review process. The annual treasure hunt yielded double-digit suggestions for further engineering review and possible implementation.

A number of reliability and efficiency improvements were successfully implemented. Annual savings of 39GWh was realised after bypassing 2x4500hp fuel gas compressors. PacificLight had chosen VSDs over the hydraulic fluid coupling to regulate the speed (and hence power saving) of the Feedwater Pumps. The design was conceived with “reliability-in-depth” in mind so that the feedwater pumps would be robust with no loss in reliability. The project was given the go ahead by the enlightened management at the time of lower energy prices.

The presentation will delve into experience sharing in the implementation of VSD in boiler feedwater pumps from the perspective of system design, equipment selection, robust switchover tests, performance evaluation and how initial problems were overcome. 5.6 GWh of annual energy savings was realised, which was 18% better than initial project estimate. The intangible benefits were significant reduction in noise level and ambient temperature in the sound enclosure of the FWP. The project demonstrated that without decoupling pump and motor, VSD can indeed achieve a reliable and have better energy savings than a conventional hydraulic fluid coupling speed driven 6.6kV motor.
