iHEPS delivers real-time energy consumption data using Devices World’s innovative iSCADA technology platform.
The goal of iHEPS is to assist major electrical energy consumers i.e. Manufacturers, in better understanding their energy consumption patterns, achieving energy efficiency, and lowering energy expenses.
iHEPS provides many benefits for buildings and facilities in terms of energy monitoring which may not be possible through traditional monitoring of electricity meters; these include:
Demand response optimisation – Maximum Demand (MD) mitigation. The prudent use of iHEPS derived information allowed for the reduction in Max. Demand (MD) by as much as 3% for a 10 MW consumer.
This resulted in a RM9,000 monthly reduction in the MD portion of the monthly electrical utility bill. Another source of savings (again using iHEPS) came from a shift from peak to off-peak consumption. Overall KWh consumption savings through this peak to off-peak shift additionally reduced RM1,500 from the same monthly electrical utility bill.
The overall savings by implementing these energy efficiency measures (facilitated by iHEPS) resulted in a total monthly saving of approximately RM10,500.
The Return on Investments for this company’s iHEPS investment was thus less than five months and the company continues to enjoy additional savings through longer term energy efficiency measures.
Bangsar Village has been utilizing Devices World’s patented iSCADA technology, via the iHEPS solution, since 2010, and during that time they have been able to reduce their Maximum Demand by over 300 KW. By using the data that was acquired by the iHEPS solution, Bangsar Village was able to consult with Devices World, their energy managers, and various maintenance departments to help reduce and optimize their energy usage.
Bangsar Village is a large, up-market shopping center that opened in 2004. Since then it has expanded to have a sister mall right next to it, Bangsar Village II.
Bangsar Village is a prime example of a standard shopping mall in Malaysia. They have around 70 tenants in Bangsar Village 1 and around 120 tenants in Bangsar Village II.
Operational challenges like high utility expenses and frequent power outages caused Wisma Central to receive complaints from their tenants and workers on multiple occasions. Wisma Central were unable to identify the usage patterns of their energy consumption every month, causing them to spend huge amounts of money in utilities and missed out on OPTR (Off-Peak Tariff Rider) benefits monthly. In order to receive the benefits on electricity usage during off-peak hours, max demand needed to be controlled.
In 2015, the iHEPS solution was installed and Wisma Central achieved OPTR savings and optimization of energy consumption every month by monitoring the maximum demand and load factor of their energy consumption. Through the iHEPS solution, Wisma Central were able to monitor in real-time their energy consumption, and therefore identify and augment any energy inefficiencies within their facilities.
Wisma Central is a commercial office building located right next to the iconic Petronas Twin Towers, on Jalan Ampang. Its facilities include a covered car park, cafeteria, convenience stores and more.
In July 2010, the iHEPS solution was implemented for Malay-Sino. After installation, the iHEPS system allowed them to understand their energy consumption patterns and mitigate kWh costs and Max Demand. From August 2010 – April 2011, a reduction of almost 600 kW in consumption was made. Through the iHEPS solution, Malay-Sino achieved off-peak tariff rider (OPTR) savings and optimized their energy usage every month by monitoring the Maximum Demand and load factor of their energy consumption. Over a period of 3 years, they were able to reduce their Max Demand by over 1.5 mW.
Established in 1973, Malay-Sino Chemical Industries Sdn Bhd is a company which specializes in manufacturing Chlor-Alkali chemicals, being Malaysia’s largest manufacturer of these products. Their products are used in a variety of fields including paper manufacturing, textiles, detergents, electronics, and more.
Being a large manufacturing company, Malay-Sino utilize huge amounts of electricity on their production every month. This heavy amount of electrical consumption requires that their facilities optimize production so as to prevent inefficiencies in cost.
Devices World engaged with SOGO in 2011 to install the iHEPS system to monitor their energy consumption. Utilizing the iHEPS system, they were able to justify the purchase and replacement of their older chiller units to newer, more efficient units. This modification resulted in a drop of more than 300 kW in consumption. Since then, Sogo has gone on to further reduce their MD by an additional 800 kW, amounting to a total reduction of 1.1 mW over a 6 year period.
SOGO, Kuala Lumpur (also known as KL SOGO) is a large single department store in Malaysia. It is located at a site formerly occupied by Suleiman Courts apartments located at Jalan Tuanku Abdul Rahman, one of the main shopping streets of Kuala Lumpur. KL SOGO commenced business on 18 January 1994.
Devices World develops, designs, engineers and installs a variety of solutions customized to enable precise measurement of instantaneous demand, and control demand as required to mitigate energy costs. Our innovative solutions help our customers achieve a maximum demand that conforms with their requirements to reduce monthly energy bills.
