The conversation was getting heated and it ended with the statement “Diesel Generators are cheaper than the Electricity Company of Ghana (E.C.G) and some businesses in Ghana run on generator power even when the grid is available”……………………..

This was what I learnt from a conversation I had in 2014 with an associate of mine who ran a medical practice in East Legon at the time.I was actually doubtful of his claims because of his political affiliation and therefore brushed these claims aside.

Whilst Ghana appears to have recovered, somewhat, from the power crisis, many businesses are, ironically, turning to generators which they find to be cheaper than the national grid. Fast forward to 2017 ,whilst running several power audits across Ghana ,I  come across several businesses who run on diesel generator power 2-3 times weekly as a cost cutting strategy for electricity. Some of these business claim to be able to save up to 25% on power costs by this strategy alone.

With Ghana’s prepaid metering system, it’s easy to compare how much is spent on either generators or the national grid on weekly or even daily basis .The bare facts are that  that solar  has gotten cheaper today than it was years ago and with an average 5.5 hours of effective sunshine daily in Ghana, businesses  should seriously consider quality Grid-tied solar power systems such as Fronius .With these solar power systems you don’t need to even worry about rising utility tariffs  or fuel prices.

Most Ghana based business shy away from Solar power because of the perceived high initial costs. Grid-tied solar often has fewer upfront costs than an off-grid system. For one, it can cost less to install a grid-tied system because it does not require batteries, as off-grid does. For another, it’s more flexible, as you don’t necessarily have to install the number of panels you will need to produce all your energy needs right away. people choose grid-tied solar power  systems when they know they could only afford a certain number of panels at a given time, so their goal is to lower their electricity bills—but not eliminate them entirely just yet.

Over time, you can always add more panels as you find the financial resources to do so.This solar power option is excellent  for  commercial operations that have a high power demand during daytime hours.Up to 65% percent of power demand for most offices in Ghana is for air-conditioning /cooling due to high daytime temperatures  and humidity.  Our research indicates that grid tied solar can be at least 45% cheaper than off grid solar power systems and you can save Ghc 24,000 per annum by the deployment of just 10kwp.We are able to calculate the savings because of the inbuilt monitoring systems in these intelligent devices built by Fronius BV of Austria.

Erratic power supply AKA Dumsor has always been hot topic these past few  years .Pronounced “doom-sore” (or more appropriately dum sɔ, “off and on”) is a popular Ghanaian term used to describe persistent, irregular and unpredictable electric power outages. Everybody from businesses to households has been affected one way or the other. In addition to this most Ghana residents have had to spend 200-300% more than what they used to spend on electricity five years ago.

2016 Its an election year in Ghana and I hear lot of promises from political parties and politicians alike. These promises include, good roads, education, health, jobs and of course Energy .

Can we be brutally honest with each other as Ghana residents?

  • Our energy demands have risen over the years and we require more capacity
  • Energy prices have risen all over the world and reliance on only hydro isn’t sufficient for Ghana anymore
  • There is no political party that can reduce electricity tariffs to rates that were being paid 5-10 years ago. Even if anybody tried, it wouldn’t be sustainable
  • Electricity prices will continue to rise in the coming years and the time to change our mindset is now
  • Ghana needs a serious national policy plan /implementation on energy matters

I have to admit times are pretty hard in Ghana these days. A lot of people are unable to pay their utility bills. Some have actually resorted to either connecting utilities illegally or using less. A good number of people have been caught some of them being foreign business and all .I also know a few people who switch off their refrigerators or deep freezers at night.

Another interesting fact is that for those who are buying new electrical appliances, price becomes the most important or deciding factor so much  such that efficiency is thrown out of the window.

While interacting with people we get these statements quite frequently: So you tell people to use less electricity and conserve it?” or “Your website has ideas on how to buy appliances, how does that relate to saving electricity?” The easiest way to save energy (or electricity) is to use less of it, but we have to be realistic in our approach. Our lifestyles are changing, and with increased pace of development, our need for appliances is increasing and so is our need for energy.  Thus the ideal mix to save energy will involve both conservation and efficiency. Now let us look at what is the difference between the two.

What is Energy Conservation?

Whenever you use less of something that means that you are trying to conserve it. So if you use a 1100cc vehicle instead of a V8 vehicle, it means that you are trying to conserve fuel (among many other reasons why you would prefer to use 1100CC over a V8 motor vehicle). If you switch off lights when they are not needed, then you are conserving energy. When you increase the temperature at which you operate your air conditioner from say, 24 degrees to 25 degrees, you are conserving energy. You also conserve energy when you switch off your DSTV decoder boxes and TVs when they are not in use.

Energy Conservation is all about using energy only when it is required and using it as much as needed for the job and not wasting any amount of it. It requires a conscious effort from the user of energy to make sure that there is no wastage on a regular basis. It requires a lot of behavioral change and needs effort. It may not need any investment always.

So what is Energy Efficiency?

Energy efficiency in contrast means using lesser energy to do the same job. When you buy a car that gives more mileage, you use less fuel to travel the same distance. When you buy a 5 star rated air conditioner instead of a 3 or 2 star rated air conditioner, it means that for the same usage and in same conditions, you use less electricity (for the same temperature at which you operate them). If you use a 5 star rated air conditioner at higher temperature, you double the effect and combine energy efficiency with energy conservation.

Energy efficiency has more impact on your personal finances. An efficient appliance may cost more than an inefficient appliance. Although the additional capital cost may get recovered in form of electricity savings. Energy efficiency may not require physical effort but requires change in people’s buying patterns. It requires knowledge of various products and their efficiencies. If people start buying more of efficient products, manufacturers will start producing more of them.

Conclusion

Both energy efficiency and energy conservation have the same goal: to save energy and the same impact: saves money. Both can individually save energy but when coupled together can save double the amount of energy and money. It depends on your choices as to which one you like to do. A good mix of the two can ensure high savings with low investments and efforts.


Air conditioning & the rising electricity tariffs in Ghana

My Nigerian friends often say Ghanaian folk have a signature look, very dark skin and red eyes. This they claim is as a result of the scorching sun in Ghana. Ghana is hot o…….

Average temperatures often range between  35-40 degree Celsius with high levels of humidity . Due to the nature of the weather in Ghana Air-conditioning is no longer a luxury.Most homes and offices who can afford , have invested in one form of cooling or the other while those who cant have settled for fans.But what happens when there is erratic power supply and load shedding  AKA Dumsor  in Ghana? I bet that is another topic for another day.

Recent electricity price hikes in Ghana have made Air Conditioners a pain point for most who are concerned about their electricity bills. Electricity bills increase significantly when an air conditioner is added to the list of appliances in a household. Although it is difficult to significantly reduce the “big” impact of an air conditioner on your electricity bills, it can be managed by choosing the right technology, and following the right installation/maintenance/operation procedure and also putting into consideration the insulation of room where the air conditioner is being operated.The latest and the most efficient technology that is available on market today is the Inverter Technology for air conditioners. Inverter technology is designed in such a way as to save 30-50% of electricity (units consumed) compared to regular air conditioning systems.At Nocheski ,we live up to our promise of driving your business with technology and we recommend the use of energy efficient appliances such as inverter Air-conditioners from brands including LG,Daikin and Samsung , Gencool just to name a few.

How do air conditioners work?

For most people, air conditioner just throws cool air at the temperature one sets it at. But does it really work that way? In principle, an air-conditioner during the cooling process, takes the indoor air, cools it by passing it through evaporator and releases it back in the room. It is quite opposite to how our good old air coolers used to work. Air coolers used to take outside air, cool it with water and throw it in. But air conditioners just work on internal air. Along with evaporator an air conditioner also has a compressor that compresses the gas (refrigerant) in the AC to cool it that in turn cools the incoming internal air from the room.

In a regular air conditioner:

The compressor is either off or on. When it is on, it works at full capacity and consumes the maximum electricity it is designed to consume. When the thermostat reaches the temperature level set in the AC, the compressor stops and the fan (in AC) continues to operate. When the thermostat senses that the temperature has increased, the compressor starts again.

Air Conditioners with Inverter Technology

The inverter technology works like an accelerator in a car. When compressor needs more power, it gives it more power. When it needs less power, it gives less power. With this technology, the compressor is always on, but draws less power or more power depending on the temperature of the incoming air and the level set in the thermostat. The speed and power of the compressor is adjusted appropriately. Originally developed in Japan for use in air-conditioning systems, digital inverter technology is now applied globally in appliances such as refrigerators, washing machines and even microwave ovens.

What is benefit of Inverter Technology?

Every air conditioner is designed for a maximum peak load. So a 1.5hp AC is designed for a certain size of room and 1 hp for a different size. But not all rooms are of same size. A regular air conditioner of 1.5hp capacity will always run at peak power requirement when the compressor is running. An air conditioner with inverter technology will run continuously but will draw only that much power that is required to keep the temperature stable at the level desired. So it kind of automatically adjusts its capacity based on the requirement of the room it is cooling thus requiring less electricity for efficient operation although air conditioner with Inverter Technology adjusts its capacity based on the room requirement, it is very important to install a right sized air conditioner in a room. Please make sure that you evaluate the room and air conditioner capacity before you make a purchase.For further clarifications on this subject ,you may contact our produuct specialist in Tema  here
