Success story: Money Printing Company

A factory “with plenty of money” but with an efficient way to spend, only the exact amount of energy they need to produce it.

PERUM PERURI is a state-owned money (IDR rupees) printing company located in Indonesia, with offices in Jakarta, Karawang and Surabaya. They have drawn to export their money manufacturing capacity at the service of other countries as well. PERUM PERURI in its aim to be more sustainable and making constant energy conservation in their manufacturing process decided to float a Power Factor Correction System and Solution tender in 2017, in which CIRCUTOR along with its local skilled and experience system integrator PT. ELCO POWER SYSTEM, were awarded because of the technological solution offered along with the value for money. Besides they built the counter performance contract and include the scalability of the solution, as part of a full integrated Energy Efficiency solution plan.

As a matter of fact, CIRCUTOR is vastly experienced in correcting the unnecessary wasted energy commonly known as “reactive energy” produced by the motors among other loads. However, what made this project special and peculiar were the technical and physical constraints and little challenges that CIRCUTOR had to overcome. With such hidden difficulties, only by being a vanguard manufacturer on Power Factor and Harmonics Mitigation products with expert local partner, you are really able to deploy, offer and install the right solution that end user, in this case PERUM PERURI, needed.

In less than 7 months, the application was able to return the customer's investment...
Our solution was a customized OPTIM-FRE capacitor panel (2400 kVAR) fitted with reinforced detuned filters (harmonics distortion protection). It was conceived to compensate the power Factor at Medium Voltage coupling point but with a step-up voltage transformer in low voltage and thyristors driven operation. We had to bring the current sensing from 2 different sites at the same time with a summation CT to the “brain” of the panel, which is our Power Factor Regulator Computer Smart III, and far away from the capacitor panels. In less than 7 months, the application was able to return the customer the investment, with full operational system so far. Not only that, but thanks to the Electric Parameters incorporated in our automatic power factor regulator we had the chance to offer our PowerStudio SCADA energy supervision system, as part of the solution of comprehensive monitoring and to control all the time the status of the panel and the benefits of constant energy savings.

SAVINGS

€200,000 per year

 

INVESTMENT

€150,000 per year

 

PAYBACK PERIOD

5 years


Objectives:

To optimise the consumption of energy of the installations of the UPO


Results:

  • ––The cumulative savings from 2011 to 2014 were 26.47%, compared to the 2011 Reference Baseline.
  • ––It is worth mentioning that phases II and III of the Library were started in 2012, which led to high monthly consumption figures. The consumption of this building was further reduced years later by implementing more exhaustive controls.
  • ––This has resulted in savings of approximately 200,000 euros per year.

 Main consumption control

Initial situation

Energy demand management is starting to become a vital element of the energy policies of organisations and, in particular, of Spanish universities. The reduction of energy demand is a very economical way of achieving the objectives of reducing the costs of energy supply, minimising the environmental impacts and increasing energy safety.

Taking these premises into account, since the foundation of the Pablo de Olavide University (UPO) in Seville in 1997, the Infrastructures, Maintenance and Energy Efficiency area (IMEE) and Computing and Communications Centre (CIC), led by the administration of the UPO, have been increasingly concerned about establishing quality Energy Efficiency management mechanisms for the installations and buildings of the campus, as well as raising awareness on "shortages in the availability of energy and its environmental impact", with the participation of the whole university community in achieving these objectives.

In turn, the infrastructures of the University have grown from 1997-2015 (buildings and installations used for teaching, research and administrative management), which require the efficient management of the matters described in these good practices (management of light, drinking and irrigation water and air conditioning systems, attendance control systems, fire alarms, fire extinguishing systems, surveillance systems, etc.).

SAVINGS

25-30% of consumption

 

INVESTMENT

€80,000

 

PAYBACK PERIOD

3 years


Objectives:

The main objectives were to achieve maximum energy efficiency and maintain the level of comfort for customers


Results:

Using statistical data of similar topologies, it was estimated that implementing the system would obtain savings the first year of 25-30% over the previous year. In addition to the drastic decrease in energy costs, overload problems in lines and consumption peaks were minimised.

The change also increased customer loyalty, because port management allocated the exact costs of each mooring in the invoices without mistakes or estimated usage.


 Sea ports

Initial situation

The Port of Barcelona experienced a 60% increase in the electricity bill due to continual increases in the cost of energy. At the same time, users of the moorings wanted to enjoy the same commodities they have in their usual dwellings, and so were using all types of household appliances, air conditioning and heating devices, without being aware of the extra costs they were incurring.

This situation caused the overloading of existing lines and difficulties for managing a network with numerous consumption points. Therefore, it was necessary to find a solution that would reduce electrical costs and decrease overall consumption without affecting the customer satisfaction rate.

Results:

From the first month following the installation, there was already a 15% electrical energy consumption saving, and all the improvement measures resulted in an average saving per centre of €32,000 the first year. The payback period for the project was eight months. 

"The detection of inefficiencies caused by inappropriate consumption schedules, such as air-conditioning at night, enabled a saving of €8,000 a year through awareness, and the programming and/or remote control of those systems". 

Other savings were also confirmed, both in terms of use and maintenance, which facilitated a rational use of energy in the installations, including remotely via the WEB platform. Other improvements were achieved through the use of calendars to rationalise seasonal consumption


 Supermarkets

Initial situation

The energy systems manager of the shopping centre chain detected extra costs in electricity bills. This manager is responsible for establishing the objective to improve the energy efficiency of the installations. There was no energy consumption forecast or possible comparison between similar centres of the same chain.
