Get to know the city of Surabaya
Surabaya is the second largest city in Indonesia after Jakarta. This city is located on the north coast of Java Island and is the capital of East Java Province. Surabaya has an area of around 374.8 km² with a population of around 2.9 million in 2020.
Surabaya’s history is very long, starting from the Dutch colonial period to the struggle for Indonesian independence. This city also has the nickname “City of Heroes” because of its important role in fighting for Indonesian independence. This city is a silent witness to various historical events in Indonesia, starting from the Hindu-Buddhist era, the Majapahit kingdom era, to the Dutch colonial period and the struggle for Indonesian independence. The city of Surabaya has a strategic location as a center for trade, transportation and industry in East Java.
The city of Surabaya has many interesting tourist attractions, such as the Heroes Monument, Submarine Monument, Cheng Ho Mosque, Mpu Tantular Museum, Bungkul Park, and various shopping centers such as Tunjungan Plaza, Pakuwon Mall, and Galaxy Mall. Apart from that, Surabaya is also known for its various culinary specialties, such as Soto Lamongan, Rawon, Rujak Cingur, Lontong Balap, and many more.
The city of Surabaya also has quite good infrastructure, such as toll roads, international airports, sea and river ports, and trains that connect Surabaya with other cities in Indonesia. Apart from that, Surabaya also has many leading educational institutions, such as the Sepuluh Nopember Institute of Technology (ITS), Airlangga University, and the University of Surabaya.
However, like other big cities in Indonesia, Surabaya also has various problems, such as traffic jams, air pollution, and waste management that is still not optimal. Therefore, the Surabaya city government continues to work to overcome these problems by developing sustainable programs, including the application of renewable energy.
Development of Renewable Energy in the City of Surabaya:
Technological developments and increasing energy needs are a serious problem for countries around the world. One solution that is considered the most effective in overcoming this problem is the application of renewable energy. Renewable energy is an energy source that comes from renewable natural resources such as solar, wind, hydro, geothermal and biomass energy. In this article, we will discuss the application of renewable energy in the city of Surabaya and what innovations can be applied to achieve sustainability in the future.
Along with the rapid economic development, the need for energy in the city of Surabaya is increasing. However, the dominant use of conventional energy, such as oil and natural gas, produces high greenhouse gas emissions and has a negative impact on the environment and human health. Therefore, the use of renewable energy is an alternative that can reduce these negative impacts.
One of the renewable energies that can be applied in the city of Surabaya is solar energy. The city of Surabaya has great potential in utilizing solar energy considering its location in the tropics. In addition, hot and sunny weather throughout the year can maximize the use of solar energy as an alternative energy source.
To apply solar energy in the city of Surabaya, this can be done by installing solar panels on the roofs of buildings or other buildings that have the potential for utilizing solar energy. In addition, the government can provide incentives for people who use solar energy by providing subsidies or tax breaks.
Apart from solar energy, wind energy can also be applied in the city of Surabaya. We can take advantage of the sea breeze on the north and south coasts of the city of Surabaya as a source of renewable energy. In applying wind energy, this can be done by building wind turbines in coastal areas that have strong and stable winds.
Apart from solar and wind energy, the city of Surabaya also has the potential to utilize water energy as a renewable energy source. One source of water energy that can be utilized is hydropower produced by waterfalls or rivers. The government can build water turbines in these areas to utilize the energy potential of the water.
In addition to implementing renewable energy in the energy sector, the Surabaya city government can also promote the use of electric vehicles as an alternative to conventional engine vehicles which are still dominant. In implementing electric vehicles, the government

Most Americans, me included, are puzzled as to how the Trump administration can openly thumb its nose to the findings of our courts. Until recently, behavior like this would have wound you up in jail.
Over the decades, many households across Victoria have resided in older suburban homes equipped with traditional ducted gas heating and aging split-system air conditioners.
However, today the scenario has changed significantly. As energy prices rise, families are feeling the pinch, with annual heating and cooling costs often rising $2,000.
But what are the main issues?
Gas systems that waste energy heating unused rooms, old non-inverter aircons that struggle to maintain even temperatures, and confusion among residents about how rebates, such as the Victorian Energy Upgrades (VEU) program, actually work.
That’s where trusted providers like Cyanergy Australia step in!
By replacing outdated systems with efficient reverse-cycle multi-split air-conditioning and applying VEU rebates, we help many households to cut energy bills, reduce emissions, and enjoy year-round comfort, all in one smart upgrade.
This air conditioning upgrade can lead to a smoother transition from gas to clean, efficient electric heating and cooling, building a smarter, more sustainable home.
So, let’s break down how the household saved $1,200 with the VEU & Air-Con upgrade, what the program offers, and how you can take advantage of similar rebates to cut costs and enjoy a more energy-efficient home.
Cyanergy’s Energy Assessment: What We Found!
From the beginning, Cyanergy’s focus was to remove or disconnect the old gas ducted heater, install a modern
reverse-cycle multi-split air conditioning system, claim the VEU discount, and significantly reduce your annual
energy bills.
Simply via the effective air-conditioner upgrade, households can “Save
up to $2,000 a year on your energy bill.
Here are the findings after Cyanergy’s initial home energy visit:
- In many Victorian households, the ducted
gas heater is still in use, with high standing and fuel costs. - The older split system had poor efficiency. Some of them were oversized for the room and lacked zoning
options. -
The electrical switchboard had spare capacity to support a multi-split installation. For example, one
outdoor unit
with multiple indoor units for different zones.
Home Heating & Cooling Upgrade| The Step-by-Step Path
It’s well-known that the upgrade path usually involves replacing old systems with modern, energy-efficient solutions.
So, from gas to an energy-efficient electric system, let’s have a look at the upgrade story:
Choosing the right system
For the households that want to upgrade under the VEU air
conditioner rebate, we proposed a multi-split reverse-cycle system:
- One efficient outdoor inverter unit connected to three indoor units
- One in the main living area, one serving the upstairs bedrooms, and
- One for the downstairs zone, which had very little heating or cooling.
- Going multi-split provides flexibility: you only run the zones you need, resulting in lower energy
consumption.
However, in Victoria, Cyanergy is a renowned company that handles design, quoting, installation, and also guides
families through rebate
eligibility.
Decommissioning the old gas ducted heater
As part of eligibility for the VEU discount, the existing gas heater needed to be decommissioned in most cases.
This involves removing the system or disconnecting the ducted unit from the gas supply, following proper procedures
and obtaining certification, and utilizing expert installers.
Installation Process & Timing Period
- Initially, after checking the eligibility, apply for the quotes.
- The quote needs to be accepted and dated.
- Then the installers will remove the old ducted heater, seal off the vents, and remove or disconnect the gas
appliance. - The outdoor inverter unit should be mounted externally in these households. The indoor units need to be
installed in each zone, minimising the intrusion of ductwork and piping. - The wiring and electrical breaker must be upgraded as needed.
- The system will then be commissioned, and the necessary documentation will be submitted to the accredited provider for the VEU scheme.
Choosing efficiency over just cooling
Rather than improving just cooling, the Victorian households treated the upgrade as a heating & cooling renovation, switching to a system that uses electricity rather than gas.
Modern inverter systems are more efficient, as they modulate their output, offer better zoning, and can both heat and cool, allowing you to enjoy both winter comfort and summer cooling in one system.
At Cyanergy, we emphasise this home upgrade path:
“Efficient and Eco-Friendly Electric Multi-Split Air Conditioner. Take advantage of up to $7,200 in Victorian Government Energy Upgrade incentives, save big this winter on your gas bill.”
Out-of-pocket and rebate
Here is recent data from the average estimation for a household from the aircon rebate case study in Victoria.
In the quotation, the family had an installation cost of approximately $8,000 for the new multi-split system, including the decommissioning.
The VEU discount for gas-ducted to multi-split upgrades in Victoria was approximately $2,500.
So, their net out-of-pocket cost was ($8,000 – $2,500), which is approx $5,500.
How to Apply for the VEU Rebate: Are You Eligible?
The Victorian Energy Upgrades (VEU) program provides rebates for eligible energy-efficient upgrades such as
installing a high-efficiency reverse-cycle air conditioner to replace an older heating or cooling system.
Before we discuss how
the rebate works, here are the eligibility criteria.
So, to qualify under the VEU program:
- The property must be more than two years old.
- The existing heating or cooling system must be removed or replaced.
- The new system must be an eligible high-efficiency reverse-cycle unit installed by an accredited
provider.
How the Rebate Works
In this case, the quote from Cyanergy already included the VEU discount, meaning the price shown was the net cost
after applying the rebate allocated to the installer.
After installation:
- The accredited provider registers the upgrade with the VEU program.
- They create and claim Victorian Energy Efficiency Certificates (VEECs) for the upgrade.
- The value of those certificates is passed on to the customer as an instant discount on the invoice.
The homeowner simply has to:
- Signs off that the old system was removed or decommissioned.
- Provides any required evidence or documentation, like serial numbers or photos.
The Result
The rebate is applied instantly at the point of installation, reducing the upfront cost — no need for the homeowner
to submit a separate claim.
Why is the VEU rebate significant?
Rebates like this make a big difference in the decision-making process. As the website says:
On average, households that upgrade
can save between $120 and $1,100 per year on their energy bills.
Additionally, the government factsheet notes that households can save between $120 and over $1,000 annually,
depending on the type of system and upgrade.
Thus, the rebate reduces the payback period, making the system more widely available.
Energy Bill Before vs After: See the Savings!
Here’s where the real story says: the household’s actual bills before and after the upgrade.
Before Adding Air Conditioning System
- Ducted gas heating and an older split system.
- In Victoria during winter months, the average monthly gas cost is approximately $125, and for electricity,
and other supplementary costs, an additional $30. So roughly $155 per winter month. Therefore, over the
course of four months, the price can reach nearly $620. - In summer cooling months, if their older split system ran for 2 hours per day, for example, from May to
October, it would cost around $50 per month. Over the 6 months, it will be, $300. - Total annual heating and cooling cost is approximately $920
After Adding the Air Conditioning System
- Household that installed a Multi-split reverse-cycle system.
- During the winter months, running the zones efficiently and utilizing the inverter system resulted in a
decrease in heating electricity costs.
Let’s say the average is around $70 per month over four months, totaling approximately $280.
- In the summer months, efficient cooling costs approximately $30 per month over six months, totaling around
$180. - So, the annual heating
and cooling cost is approximately $460.
Net Savings
Annual savings: $920 (before) – $460 (after) = $460 per year.
At that rate, the upgrade pays for itself in net savings and an upfront rebate.
However, as they also removed gas connection fees and standing charges, improving comfort, therefore, the “effective”
savings were perceived to be higher, around $1,200 in the first year with the air conditioning upgrade.
This figure also includes avoided gas standing charges of $150, lower maintenance costs of the old system, and
improved efficiency.
Maximising Your Savings| Key Insights from the VEU Rebate Program
Based on the case study and Cyanergy’s experience, here are some lessons and actionable tips for homeowners
considering an upgrade.
- Don’t wait until your system dies.
Replace outdated or inefficient gas or electric resistance systems immediately. Once the system starts
failing, you
may have fewer options or higher installation disruption.
- Choose a provider who handles the rebates.
Dealing with the rebate or discount component (VEU) on your own adds complexity, like documentation,
compliance, and
installation. So look for an accredited provider.
- Understand the actual savings potential.
It’s not just the rebate amount; consider running costs, efficiency improvements, zoning, and the ability to
heat and
cool.
- Ensure proper sizing and zone control.
As many families discovered, the benefit came from zoning: you only heat and cool rooms you use. Oversized
units or
whole-home heating can reduce savings.
- Factor in non-energy benefits.
Better comfort, for example, quieter systems and more consistent temperatures, as well as the removal of gas
standing
charges, less
maintenance, and improved resale appeal for eco-conscious buyers, all benefit you.
- Check the accreditation and compliance.
With rebate programs, there’s always a risk of non-compliant installations or companies that don’t follow
through.
So, do your homework: check that the installer is accredited for VEU, ask for references, and ensure that the
documentation is completed appropriately.
- Request detailed quotes that include estimates for both “before rebate” and “after rebate”
costs.
This helps you see how much you’re actually paying, the discount you receive, and ensures transparency. The
rebate is
not always the full difference; minimum contribution rules apply.
- Monitor your bills after installation.
Keep track of your energy bills (gas & electricity) before and after for at least 12 months. This will
indicate
whether the savings are as expected and aid in budgeting.
Be realistic about pay-back
Although the rebate helps upfront, large systems still cost thousands of dollars. Don’t expect payback in one
or two
years (unless you have extreme usage).
However, with a well-designed system, rebates, and efficiency gains, a payback of 5-10 years or better is
possible,
depending on usage.
Final Notes
This aircon rebate case study illustrates the VEU saving. By working with Cyanergy Australia, households transformed a traditional, inefficient gas-ducted heating and older split cooling system into a modern, efficient, zone-controlled multi-split reverse-cycle air-conditioning system.
This was made more affordable through the VEU scheme discount.
The result? A net cost of around $5,500, improved comfort, and savings of approximately $1,200 in the first year.
This real-world “VEU saving example” shows that:
- Rebates matter as they make the upgrade financially viable.
- Efficiency matters as modern multi-split reverse-cycle systems deliver lower running costs.
- Removing inefficient gas heating can unlock significant savings.
- A reliable installer who navigates the rebate process effectively is crucial.

About 20 years ago, a friend asked me if I was aware that cars could run on air. I asked, delicately, what she meant, and she explained that cars can run on compressed air.
“Ah,” I replied. “Of course they can. But where does the energy come from that compresses the air?” End of conversation.
Now, it’s back. Now there are enormous swaths of the population who know so little about middle school science that they believe we can put cars on the road, in an ocean of air, and extract energy out of that air to power our automobiles.
If you’re among these morons and want to invest with some heavy-duty fraud/charlatans, here’s your opportunity. They say that it’s “self-sustaining and needs no fuel.” If that makes sense to you, be my guest.
