With a nice balance between geothermal, hydroelectric, unusually continuous wind power and some solar, the country has less intermittency of green power than most. Transpower NZ, the government-owned power company, made NZD 208.4m profit in 2016-17 (AUD 190m) and has investigated grid-scale battery systems for near-term investment. Battery storage under investigation Building energy storage systems across New Zealand would represent an economic ‘game-changer’ for the country within the next few years, according to new research by national grid owner-operator Transpower. The company said its research findings show distribution-connected or community-scale batteries are expected to be economic for homes and business from 2020— promising “real potential and benefits from batteries for New Zealand consumers”. Now Transpower is preparing to conduct trials of battery storage systems, while working with industry leaders to push for market and pricing reforms the company said will be needed to “unlock the value of battery systems to maximise their value”. Transpower’s general manager for grid development Stephen Jay said: “We are actively evaluating opportunities for using new technologies throughout our network. We are preparing for what that future looks like and this battery research is the first of a number of reports we will release looking at technologies that could possibly have an impact on our business. “Battery projects at lower voltage distribution substations and at a consumer level are forecast to be economic in the next few years, due to the declining cost of battery systems,” Mr Jay said. “Over time, we believe they will also become economic for the high voltage transmission grid and this will then provide battery resilience across the whole supply chain.” Mr Jay said Transpower is not planning large-scale high voltage trials with batteries “in the near term— but we will seek opportunities to work with and learn from others in joint projects where appropriate.” According to Transpower’s study, the functionality of a battery as both a load and a generator at various times “will need to be examined, and regulatory and technical barriers to entry addressed”. In the long-term, the study said battery storage at any location in the supply chain is expected to delay or replace the need to build additional thermal peaking plant and should over time reduce the cost of electricity to consumers. Container-based battery storage systems in the order of 1-2MW “have the advantage that they can be implemented relatively quickly to target specific grid constraints in a controlled manner”, the report said. They can be ‘right sized’ for the first year of need, “with the possibility of increasing the storage capacity over time if load growth occurs”. This would “optimise initial capital expenditure and leverage the declining cost curve of future expansion”, the report said. In addition, the report said ramping up battery storage projects would support national plans to boost the take-up of electric vehicles. According to Transpower, there are currently around 3,000 electric vehicles in the country, but government policy is targeting 64,000 vehicles by 2021-22. “In future, we expect that electric vehicle batteries could have the capability to be part of a battery network, providing services when the vehicle is plugged in to charge overnight,” Transpower said.

Next Generation: the long-term future of the National Electricity Market calls for preparatory work on a ‘capacity mechanism’ to encourage investment in new electricity generation and reduce the threat of shortages and blackouts. The report warns, however, that the costs of such peace of mind would ultimately fall on consumers through higher electricity prices. So a capacity mechanism should be introduced only if all other market reforms have been exhausted and supply is still under threat. Through a capacity mechanism, generators would be paid not only for the electricity they produce to meet current demand, but for committing to provide power for years into the future. The market operator or retailers could contract for sufficient electricity to meet future demand, to ensure new generation and storage is built in time. “Australians have endured a decade of toxic political debates about climate change policy, South Australians suffered a state-wide blackout last year, consumers across the country are screaming about skyrocketing electricity bills, and energy companies are shutting down big coal-fired power stations,” said Grattan Institute Energy program director Tony Wood. “It is understandable that governments feel the need to ‘do something’. But the danger is they will rush in and make things worse. What Australia needs now is perspective, not panic.” The Australian Energy Market Operator (AEMO) last week called for a ‘longer-term approach’ to ensure electricity supplies. The Grattan report identifies a capacity obligation on retailers as the most effective and lowest-cost approach. The report calls for a three-step policy. First, the Federal Government should implement all recommendations of the June 2017 Finkel Review, including a Clean Energy Target or a similar mechanism to price greenhouse gas emissions. Second, alongside the Australian Energy Market Commission’s work on the market’s reliability framework, AEMO’s annual assessment of future supply and demand should be extended to include a more comprehensive assessment of the future adequacy of generation supply. And third, if the newly created Energy Security Board concludes that projected shortfalls are unlikely to be met under the current market design, AEMO should introduce a capacity mechanism. “This pragmatic, planned approach offers the best prospect of affordable, reliable, secure and sustainable power for Australians,” Mr Wood said.

The good: sugar Queensland Minister for State Development Dr Anthony Lynham said the MSF Sugar biorefinery was part of a multi-million dollar investment in 21st century bio-futures plants that could generate more than 130 jobs in regional Queensland. “The proposed MSF Sugar biorefinery is expected to generate 80 construction and farming jobs and an additional 50 operational jobs, delivering a further boost to the region’s economy,” Dr Lynham said. “Powered by an onsite bagasse-fuelled 24 MW Green Power station, the combined biorefinery complex is expected to produce 110,000 tonnes of raw sugar, 200,000 MW of green electricity for the grid and 55 million litres of ethanol biofuel annually.” The company will trial large-scale blue agave cropping as an alternative feedstock to sugarcane in the off-growing season, which could potentially allow the biorefinery to operate 12 months of the year. Blue agave is said to grow well in dryland conditions with minimum irrigation required. Dr Lynham said the government was providing funding that would primarily be used by the company to progress feasibility studies, to accelerate construction commencement of the proposed biorefinery. Dr Lynham said Atherton’s MSF Sugar biorefinery was another step towards achieving the state’s plan for a $1 billion sustainable, export-oriented biotechnology and bioproducts sector. Acceleration of the Atherton project came out of the government’s $4 million Biofutures Acceleration Program that offers support to companies to build commercial-scale biorefineries in regional Queensland to process materials such as agricultural and industrial waste. “More than 120 parties indicated interest in biorefining in Queensland through the program and 26 submitted detailed expressions of interest,” he said. Other biorefinery projects coming to regional Queensland from the Biofutures Acceleration Program are:
- A biorefinery in another Queensland sugarcane region by US biotechnology company Amyris that would create 70 operational jobs. The company aims to produce 23,000 tonnes a year of a sugar cane-based ingredient called farnesene used in products including cosmetic emollients, fragrances, fuels, solvents, lubricants and nutraceuticals.
- A planned $26 million expansion of United Ethanol’s Dalby Biorefinery facility by 24ML to 100ML, creating 50 jobs. The company also plans to conduct detailed scientific studies to improve the marketability of its high-value and high-protein animal feed product called ‘dry distillers grain’ later this year.
