Title of presentationGSK Energy Efficiency practices in Utilities Operations and Capital Projects Implementation

SynopsisGSK started its energy efficiency journey in 2002, delivering a 44% energy reduction while production volume increased by 45%. Since then, GSK has implemented more than 350 energy projects. Our methodology consists of 2 important aspects:- the use of technology and management practices. The key technology is the Energy Management System that provides on-line data to allow efficient utilities operation and identification of energy saving opportunities. The GSK management practice in Singapore and its head Office has provided the catalyst and empowerment for the GSK staff to strive to achieve its ambition to be carbon neutral by 2050

The DriversEnable & sustain energy savings initiatives

The ProjectAutomated energy targeting and monitoring system

(Rockwell) since July 2005

Server & data concentrators link with IT office network.

Web based for site wide access by all users

132 power meters, 13 flow meters, 26 temperature

transmitters.

Added new flowmeters for compressed air usage as part of

air compressor asset replacement project scope. Added

new power meters for new plant expansion. Approx. 70%

of site equipment (based on kw) are monitored via power

meters.

Benefit Detect significant unexpected deviations from normal

consumption patternDiagnostic, target setting, identify opportunities,

benchmark, calculate efficiency, quantify savings. Baseline usage

Report usage – auto reports

Energy Management & staff engagement

7

• Energy Management team sponsored by site Directors. All departments are represented. Regular meeting to review energy usage and track project status.

• Staff engagement from regular Friday Exchange messages and annual campaigns

Sharing – Singapore pharmaceutical industry

800 Month 0000Presentation title in footer

• GSK has led the Biopharmaceutical Advisory Committee (Sustainability workstream), since its formation in 2011 by Singapore’s Economic Development Board

• Energy Managers from 12 Biomedical companies meet regularly to share best practices and project ideas.

• Collective target to reduce 6% energy usage every year.Excellent results achieved , 2011: 7.4% reduction. 2012: 9% reduction. 2013: 6.2% savings. 2014: 6.2% savings. 2015: 4% savings. 2016: 5.4% reduction. 2017: 5% savings

• The voice for the Biomedical industry to feedback to government agencies.

PROJECT TITLE: Cooling Tower Water Treatment Process Redesign

BEFORE

Poor water treatment control

- reduce coolinng tower and chiller

efficicncy ( fouling & scaling)

- higher chemical usage ( cost)

- higher water usage ( cost)

- more labour for cooling tower

& chiller tube cleaning ( cost)

- manual weekly monitoring

condenser

Chiller

cooling tower

conductivity meter

& blowdown valvedos ing pump with timer

& chemical drum

water top-up

- reduce cooling tower and chiller

efficiency

AFTER

Improvement

-precise chemical dosing - use traser

molecules & feedback control

- interlock with dosing pump

- on line monitoring

detect abnormalitiy for quick reaction

Benefits

Annual energy saving 409 Mwh, $53k. Improve chiller efficiency by 5%. ROI = 0.3 years.

Reduce water usage

Reduce manpower for cooling tower cleaning and chiller tube cleaning.

Reduce water treatment chemical usage

- smart logic - blowdown valve
