Making power smart

September 15th, 2015
The energy problem in South Africa has made it essential for businesses to find alternative forms of power. But how do we know when to switch between environments? INUS DRECKMEYR, CEO at Netshield South Africa discusses how to gauge when it is ideal to move off the “grid” and when to stay on it.

The energy crisis in South Africa has made the addition of alternative energy sources imperative for businesses and households across the country. So now you have power around the clock – regardless of power outages or load shedding. But how do know when to switch between environments, gauge when peak hours are or make your renewable energy solutions work to help you save costs and cut back on grid usage?

Power management needs to be carefully thought out, or you may end up spending more on your electricity bills than you did before. There is a lot of scepticism around implementing renewable energy sources because of the hefty price tag that comes with the initial lay out, but if used correctly these solutions will ultimately save you money while keeping the lights on.

So what can you do? You need to implement a single power management resource that will intelligently and proactively help you determine which energy sources you should be using when, so that you get the most out of your power and maximum return on your investment.

It is all about management, if you have a device in place to manage your power sources in the best way possible, you don’t have to. But be careful to select a scalable solution, something that can accommodate your personal business need. This is particularly relevant if you are a large enterprise, SMBs or homeowner, who has made an investment into multiple power sources, but are finding it challenging to take control and understand your power environment.

All the features, none of the fuss

When we factored all of this in we looked at what was available on the market, saw there was little to match these needs, we elected to develop a home-grown solution designed especially with South African needs in mind to help cut costs and manage your power. If you have a renewable solution in place you want to use it first, because ultimately it reduces your reliance on the grid.

We wanted something that could dynamically determine when these renewable resources were depleted and then move you back onto the grid (Eskom) power, without disruptions to your home or your business. That means happy customers that will always get the services they need, and no wailing children when the TV goes off in the middle of their favourite show.

In addition, if your power goes off at a peak time and your renewable energy stores aren’t fully “charged” to capacity, your solution must tell your system to start up and revert to a generator, if this is included in your power environment. So basically, your power is managed for you to ensure stability and business/home continuity which will in turn, enable you to get the most out of your renewable energy investment and realise ROI. It will also give you the ability to gauge the total cost of ownership in a qualified manner.

Why do I need power management?

Multiple power feeds or sources are very much the way of the future unless some massive changes are made to energy management in South Africa. When adding alternative energy sources to your power environment, the options can be overwhelming and if you don’t use a power management solution, you can’t see where the power is going or where it’s coming from and may end up throwing money down a black hole.

Ultimately it is about effective and smart power management, using the power that’s best for your needs – and pocket – so you can realise a return on your renewable energy investment. Power management is quite a new concept for South Africans, we know that it’s needed but very seldom know where to start. A large problem when it comes to renewable energy at the moment is that people want a “quick fix”. So they will purchase renewable energy and power management solutions that are of bad quality and that will ultimately cost them more than laying down initial investment on a good quality solution would have.

All you need in one solution

How does it work? By quantifying and identifying peak times and even load shedding schedules, we will set up a series of triggers in the systems that then use a type of failover model to determine which power source is needed at that moment.

Depending on your setup of the system, your power management solution should always seek to use renewable first, only electing to revert to the grid if the load requires it, helping you save on grid costs wherever possible. This is achieved via a series of pre-set priorities, determined by you before installation, priorities range from one to four with four being the most severe-case scenario.

In addition to managing your power, the solution we have developed the Nviromon, is also an environmental monitoring solution that enables the remote management of server rooms, entire business networks, and your home, remotely, from a single management console and from a single device. It can remotely open and close gates, serve as an alarm system when connected to movement sensors and sirens and will inform you of power outages as well as other environmental threats outages through an SMS or email.

Remember that power management must give you an efficient, and convenient way to manage your power and your environment with one device, so that you get maximum ROI and peace of mind. In addition, the future will see South Africans paying more for their grid electricity during peak times, so why wouldn’t you want a solution that enables you to switch to alternate sources and save money? It’s the smart thing to do.
