Businesses could save up to 33 per cent on energy costs by combining corporate renewable power purchase agreements (PPAs) and demand response, according to new data.
The Institute for Sustainable Futures (ISF), University of Technology Sydney, in partnership with WWF-Australia and Flow Power, today announced its report into the benefits of combining corporate renewable PPAs with demand response for Australian businesses.
The report, Best of Both Worlds: Renewable Energy and Load Flexibility for Australian Business Customers, outlines the prospective savings from the uptake of corporate renewable PPAs with demand response for three large Victorian-based businesses, representing the following industries – water utilities, agriculture and industrial manufacturing.
Last year, Flow Power introduced corporate renewable PPAs to the Australian market with the view to giving local businesses a way to tap into low-cost wholesale renewable energy over a long-term period.
“Demand response from businesses has a pivotal role to play in delivering reliable low-cost power for all Australians, as well as greater financial savings,” Flow Power managing director Matthew van der Linden said.
“For customers on corporate renewable PPAs, firming can be the most expensive element.
“This report shows demand response can remove the costs associated with firming and yields additional savings.
“Where the financial savings delivered to customers on corporate renewable PPAs in the past year are just a small snapshot of ten-year or more agreement, demand response gives businesses greater flexibility to control the prices that they pay.”
Utilising data provided by Flow Power and its customers, ISF evaluated the electricity consumption, operations and potential flexible usage of the three businesses – ANCA, Select Harvest and Yarra Valley Water, to determine the financial savings provided by combining demand response with corporate renewable PPAs.
Across all three businesses, demand response had the potential to reduce costs by up to 33 per cent – a figure that could translate to several hundred thousand dollars a year depending on the business.
This was in addition to the significant savings already provided through the wholesale purchase of power on a corporate renewable PPA.
|ANCA||Yarra Valley W||Select Harvest|
|Sector||Industrial manufacturer||Water Utility||Nut and Health Food|
|Demand response type||Shut down of non-essential plant||Onsite generation||Shut down of non-essential plant|
|Reduction in energy costs (on top of modelled PPA savings)||2.3%||24%||33.3%|
The modelling used the financial savings provided through corporate renewable PPAs as a baseline for estimating the additional financial savings that each business could expect from active demand response.
It also assessed varying approaches to demand response, such as shutdowns of nonessential operations and on-site eletricity generation.
ISF research consultant and lead author of the report Jonathan Prendergast said demand response has great potential to reduce costs for the electricity grid and for customers.
“Our analysis of on-the-ground data confirms that well-implemented demand response can achieve cost savings and manage risk for Australian business customers paying wholesale rates,” he said.
