ENERGY USERS
Energy users contemplate the market A conversation with Energy Users Association of Australia chief executive Andrew Richards who says large energy users are employing significant innovations and lateral thinking to manage cost, reduce gas use where possible and find alternative solutions to the high cost challenges they face.
“While rooftop solar creates a great opportunity for homeowners, the huge expansion and lack of transparency of generation is putting a lot of pressure on networks and AEMO … one person used an analogy of a car which can drive in reverse, but it is not primarily designed for this purpose and in reverse, it has limitations.” 40 WINTER 2019
IN THE ABSENCE of lasting national energy and climate policy, the challenges faced by large energy users have been amplified with costs rising dramatically in recent years, along with the threat of increased obligations and risks. To address these issues the Energy Users’ Association of Australia’s National Conference shone the spotlight on ‘Sorting Fact from Fiction’. Speakers included Clare Savage from the Energy Security Board, Paula Conboy, outgoing chair of the AER, and Nicole Ross of the ACCC. Discussions centred on the future of network pricing, a topic close to the hip pocket of large energy users whose bills now consist of a minimum of 40 per cent network costs. But who will end up paying for the fundamental changes shaping the market? “A big challenge in the huge transition taking place in electricity markets is the impact of what is now fast becoming a two-way grid with increased Distributed Energy Resources. AEMO’s Integrated Services Report indicates huge expansion of the network to pick up new renewable zones which will mean increased costs,” Andrew Richards said. “Working out how this is prioritised so as not to increase costs unnecessarily on all energy users is critical. So too is looking at total system cost as we bring increasing volumes of renewable energy into the system.” He said that with the enormous transition underway a better understanding of the total system cost of the transformation of the energy system is vital. “Only then will we really understand the implications and costs that will flow on to energy bills.” In particular new ways of funding the transition need to be explored, especially the increased costs associated with the “rewiring” of the grid, and the EUAA wants to see a more equitable sharing of costs and risks amongst all market participants rather than the cost burden falling entirely on consumers.
Andrew Richards listed other matters under consideration, including the lack of energy policy that continues to create uncertainty and increasing costs. Part of the response from large energy users is to enter into corporate PPAs directly with new entrant generators as a price hedge. “Large users are driving new large-scale projects through PPAs which underwrite their cost as it gives the ability of large business to create some certainty on energy prices for a set period. This situation is unlikely to change irrespective of RET finishing,” he said. In gas, more supply is needed to create greater competition but this alone is not likely to bring prices down. Implications for gas users of no action to address issues in the gas market are dire. According to EUAA large energy users are innovating in their businesses (with some presenters discussing drastic diversifications), the way they source energy and how they use energy to manage cost and improve sustainability outcomes; and finding least cost firming solutions is high on the agenda.
A role for more renewables? We asked Andrew if there was much discussion over investment in renewables by large energy users to lower power costs in the long term. While rooftop solar creates a great opportunity for homeowners, the huge expansion and lack of transparency of generation is putting a lot of pressure on networks and AEMO, he said. “In relation to networks, one presenter at our National Conference used an analogy of a car which can drive in reverse, but it is not primarily designed for this purpose and in reverse, it has limitations. “It is the same for our electricity network which was not designed to take huge amounts of energy off
