Finding the energy

Make an energy management plan

Investment level: $0

Payback time: 0 – two months

Consuming energy is often a very passive act. We use lights, heat, air con, plug sockets etc, and never really think about whether we could use them less, or differently. Then we’re surprised by the bill at the end of the month.

It can be a more proactive experience though, and creating an energy management plan is the first step to that. 

First, take a look at your business and how it uses energy. “Do you leave the shop lights on all night? Why? Do all your staff members shut down computers or mobile POS systems? Is electronic equipment switched off at the wall? Are you running half-empty fridges that could be merged? There’s a helpful checklist on the EECA website,” says Paula Cooper from the EECA.

Once you have assessed your business’ immediate energy needs, write a checklist of changes you feel you should make. Shutting down all electrical equipment at night, making the most of natural light with opened curtains and clean windows, making sure you don’t have the heating or cooling systems on when a window or door is open – they’re all common sense, easy wins.

“Finally, and this is the key to making it work, you need to get staff buy-in,” says Cooper. “There’s no point in writing energy efficient procedures if no one follows them.”

It’s important for senior staff to show leadership in this area, but enable everyone to take ownership and feel they are making a difference by setting up a multi-level team to implement the new policies. Review regularly, give updates so people can see the effects of adhering to the programme and keep an open dialogue with staff so you can gauge changes in organisational behaviour.

Energy saving tips from Meridian

  • Fit LED lighting. It uses less than a fifth of the power of normal light bulbs. Turn lights off after hours.
  • Upgrade kitchen and catering appliances. Modern appliances are much more energy efficient. Keep equipment well ventilated.
  • Check window seals and insulate your outlet’s ceiling and under floor.
  • Install an auto-close external door to avoid letting too much hot or cold air in.
  • Use sunshades on hot days to reduce the ambient temperature naturally.
  • Turn off all non-essential equipment at the wall at the end of each day.
  • Keep your heating, air conditioning and hot water systems well maintained.
  • Meridian partners with companies like Enercon to facilitate energy audits to help its large business customers identify areas where they can save power and money. Ask if you would like to take part.
  • For customers who want to make the investment in solar generation, Meridian offers competitive buyback rates for excess electricity. Currently with just over 3,500 solar customers, it believes it has the largest share of the solar market.

Light me up

Investment level: $10,000

Payback time: Over three years

Light bulbs represent an ongoing maintenance cost that’s easily overlooked. Whether you own your own High St bricks and mortar store, or rent a box in a mall, forking out for luminescence will no doubt take its toll. After all, light bulbs are expensive, and a bit of a ‘grudge purchase’ all things considered. When was the last time a customer wandered into your store and said, “Ooh, love the glow from those light bulbs”?

Until recently, New Zealand has been pretty reliant on the old incandescent bulb. In a business setting, these light bulbs can represent a cheaper upfront cost, but they also introduce a maintenance cycle that can be expensive and disruptive to customers. Recent developments in LED lighting have, however, made investing in this type of bulb a smart move for retailers.

“We changed all our forecourt lighting to LED in 2012, with the help of a grant from EECA,” says Gerri Ward, sustainability manager for Z Energy – one of New Zealand’s biggest retail outlets with 216 stores to date. “We ran the project out in partnership with Philips, but we were cautious. We invested $2.7m into the project, focusing just on canopy lighting, and EECA supported us with a $580k grant. Without that grant it would not have been economical over six months.”

Z Energy owned 212 stations at the time, and a handful already had LED lighting. The company retrofitted the remaining 171.

“We instantly got positive feedback from staff about the new lighting,” Ward says. “LEDs cast a much more even light, where as the old-style bulbs would cast pools. The LEDs meant that the forecourt was more visible making the working environment safer, and improving the customer experience.”

But what about cost? LED light bulbs are actually up to 3,600 percent more expensive than incandesents to buy, with the average consumer LED bulb costing $18 against the 50c cost for their more traditional counterpart. Although in a bulk-buy business setting you would benefit from discounts, it’s still a lot of money to fork out.

“We saw an 11 percent saving on energy costs per annum,” says Ward, who also points out that the bulbs last significantly longer than the older types. “The light bulbs have a 10 year warranty, but we expect them to be going well beyond that.” Plus, there’s practically no maintenance costs. “In a remote area like Gisborne, it could cost $500 for an engineer to replace a light bulb and be very disruptive to the business,” says Ward.

The light bulbs will pay back Z Energy’s investment next year, just five years after they were installed, and will of course continue to return that 11 percent p/a saving. Plus, Z can boast a 16 percent carbon reduction – it saves the equivalent emissions of 350 NZ homes each year. The company is so impressed it’s now rolling out LED lighting in internal areas as well.

“There’s this misperception that sustainability is something you do when times are good,” says Ward. “Our experience is an example of why that’s wrong. No one can dismiss the economical, social and environmental positives of this project.”

Electric dreams

New Zealand is reliant on electricity for so much, and we’re proud that 80 percent of it comes from renewable sources. Yet, when you look at the country’s total energy budget, only 36 – 38 percent of the energy used here is clean. The discrepancy comes largely from cars. With six out of every 10 people owning a car, and 70 percent of the vehicles on the road owned by businesses needing to get people and product from A to B, it’s no wonder the fossil fuel tally is taking its toll.

In many ways, this doesn’t make sense. Recent data from a government monitoring programme shows that petrol costs are almost back to their mid-80s high of 240 cents a litre (c/L). After a sharp rise in 2008 the average cost of petrol for the last seven years has been around 220 c/L. Diesel has followed a similar pattern coupled with steady increases in road user charges, making the cost of running a standard car quite high. In comparison, electric vehicles can cost very little to run – according to the ECA, just 30c p/litre comparatively.

“The issue is largely the upfront cost,” says Mark Gilbert, director and chair of NZ leadership organization, Drive Electric. “There are currently no Electric Vehicles (EVs) under $60k, the cheapest being the Mitsubishi Outlander.”

Until 2012, Gilbert was the managing director of BMW Group New Zealand, and is a big supporter of electric vehicles, driving one himself. He believes that EVs could be a great solution for NZ businesses in the long term.

“You pay a premium upfront, but EVs have very few moving parts. The fuel and maintenance costs are much less, so it evens out,” says Gilbert, who notes that on days when he travels out of town, he can actually charge his EV for free at Auckland Airport.

“By charging an electric car you are using 80 percent renewable energy, and it also means we have to import less fuel so there are benefits there to the economy as well.”

Gilbert still believes work needs to be done though to encourage uptake.

“There are incentives in other countries,” he says. “In the UK, around £5,000 of the cost can be covered by those. As a result, there are over 40 models on the market, from town vehicles to family cars to small vans, plus plenty of public charging points and other support.”

In New Zealand, we currently have only five EV models available, and while many energy companies – including Meridian – are introducing tariffs that help support cheaper charging of EVs, the infrastructure is still lacking.

“Very few SMEs will be able to invest $60k into an EV,” says Gilbert. “But things have improved dramatically in the last 12 months. The government is looking at an incentive package, the infrastructure is increasing, and companies like Renault are considering entering the New Zealand market. More choice will drive down cost.”
