Get rewarded for how you use power this summer

Summer is fast approaching which means that your business can get involved in demand response programs and be rewarded for how you use power this summer.

Demand response has become a hot topic in recent years.

Last year the Australian Renewable Energy Agency (ARENA) and the Australian Energy Market Operator (AEMO) launched a joint initiative to ensure stable energy supply during times in peak demand of which, Flow Power is a participant in the program in NSW.

Demand response is a simple idea ARENA explained it best when Adam Morton wrote, imagine you have turned up at the airport, e-ticket in hand, only to be told your plane is full.

There are no other flights immediately available, but the airline has a solution – if you can volunteer to miss the flight and wait for a later one you will be compensated through an upgrade, a voucher, or maybe a free night in a good hotel.

At least from one perspective you’re better off.

Inconvenienced passengers may grumble, but they also mostly recognise that supply of any good is not infinite.

And if they lose out – by choice, hopefully – they win in another way.

A similar idea is behind demand response.

Demand response is simply businesses reducing the power they draw from the grid during times when demand for power is greater than supply.

Just as it would make little sense for an airline to put on another flight for a handful of passengers, there is not much economic sense in building another power plant to service a tiny number of consumers at the few times a year when electricity use peaks.

What if, instead, consumers were offered an incentive to cut use during extreme circumstances?

The power market is a balance between supply and demand, when demand is greater than supply you can support the market and be rewarded by lower average power costs or payments for your business.

Market signals such as real time electricity prices and short-term network constraints indicate when demand response is likely to be required.

Small changes to your operations can make a big difference to your power bill and the reliability of the system.

From modelling we did on 670 Australian business last financial year, at the start of 2018, demand response could have cut South Australia’s power price by 2.7 c/kWh for all Australians.

It can include shutdown of non-essential plant, use of onsite generation or energy storage such as batteries or load shifting.

Businesses generally have more flexibility to shift demand than they realise, and new technologies are making it cheaper and easier to do so.

Getting on with the job We know you have a business to run so by signing up to demand response with us you let our experts monitor the market for you.

You receive notifications when the time comes to respond via email and text message.

In addition, for businesses who want greater control over their power we have the kWatch Intelligent Controller.

When installed on your site, the controller gives you more insight into your business, alerts and can integrate with your operation.

The controller integrates with your energy intensive equipment, so you can respond within minutes to market signals.

For more than 10 years, we have been working with Australian businesses to ensure they are rewarded for supporting the power market with demand response.

We can get you involved in a range of programs including RERT (VIC and SA), and ARENA (NSW).

To see what it’s like to participate in demand response and explore how it would work for your business, join our webinar on November 13.

Premium power supplies for food makers

NHP has released a premium range of basic power supplies that offer a cost-effective solution without compromising reliability, efficiency and application flexibility – the 1606 XLB Series from Allen-Bradley.

Ideal for use in manufacturing applications such as food and beverage, packaging, materials handling, and water and wastewater the compact 1606 XLB Series from NHP offers the highest levels of reliability to reduce downtime and optimise savings.

Rated up to 1.37 million hours mean time between failure (MTBF) and with a minimum service life-time of 47,000 hours, the efficiency figures of these power supplies range from 90.7% up to 95.2%.

Offering increased choice when it comes to finding a solution that meets your application requirements, these convection cooled units can operate from -10 C° (some units -25 °C) up to 70 °C ensuring performance in the most demanding applications.

Available in 5A (120 Watts) with an input range of 85-132V AC / 170-264V AC and 10A (240 Watts) with an input range of 170-264V AC, the outputs ranges on both models are 24-28V DC.

The XLB Series are equipped with a DC-OK signal which allows the ability to monitor the output voltage, the unit also clicks smoothly onto any standard DIN rail and features large-sized terminals which makes wiring easier.

Tasmanian raspberry farm turns to the sun

Westerway Raspberry Farm was established forty years ago by the Clark Family on 150 acres of the fertile river flats of the Tyenna River on what were old hop fields to supply the local fresh fruit trade and for processing.

Freezing was seen as the key to expanding their market, but the potential energy costs were a major obstacle.

As a solution, Westerway has installed a 50kW solar system to offset the cost of operating its irrigation pumps and a 288 cubic metre blast freezer. The solar scheme comprises nearly a nearly 200-panel system in two 2.5 metre sets 50 metres long to generate the power. The system comprising 192 x 260W Trina Honey modules were installed by Powercom solar.

Powercom Business Development Manager Rohan Windsor said that the solar panels were installed in a paddock rather than a roof as this reduced the wind loading, made it easy to face north to get maximum sun exposure and low maintenance.

“The location of the panels between the farm’s pump and freezer are ideal for maintenance and for future expansion,” he said.

Westerway Harvest Manager Richard Clark said that the freezer has revolutionised their farming operation and the solar has made it more affordable to operate.

“We need to take the fruit from the field and freeze it at its peak quality and it is not viable to slowly freeze warm fruit from the field where summer temperatures can often exceed 30 C.

“The system designed by Powercom is extremely efficient and uses the solar energy on the freezer when needed and then switches over to irrigation when the freezer is not in use.

“The idea was to capture as much energy on the farm, as we need and use it through December, January and February, when most of our activities are in high gear.

“The 2014/15 season was a good one for us especially as there is a growing demand, especially from high end consumers, for Australian grown frozen berries.

“This investment has revolutionised our farm as the solar is making the freezer more affordable to operate.

“As well as the financial benefits of using less energy, we are very happy to now have a smaller environmental footprint.”
