AESOP disrupts pumped hydro industry – Improves project profits by over 100%

We invite you to watch our 2.37m video on AESOP

AESOP (Advanced Energy Storage Optimising Program) is software that enables engineers to accurately model and optimise hybrid renewable energy storage projects.

Without AESOP, project designs lack thorough economic optimisation resulting in projects that are financially constrained.

AESOP can be applied to existing and planned pumped hydro storage projects. Applying AESOP generates significant benefits in resulting decarbonisation and in project profitability.

A design is optimised by taking years of historical price and energy data and modelling how a project would have performed as though this data was arriving in real-time. Millions of decisions using energy, price, demand and other available data determine the optimal bid stack submitted in every cycle. The sizing of various elements of the physical project can be optimised against actual historical as well as scenarios for the future which vary in price and volume to test the resilience of a model.  Using this methodology AESOP typically increases project profits by well over 100%.


The resulting plant is called a Superhybrid™. The Superhybrid provides contracted firm green energy to replace baseload and peaking power from fossil-generated plants, contracted gaseous & liquefied green hydrogen, and valuable grid services. It also assists greatly in reducing transmission requirements for grid owners.

Implementation of AESOP requires assessment of the current or planned infrastructure and investigations into potential inclusions. This process includes:

  • Examination of social licence
  • Examining potential environmental impacts
  • Developing land options for additional infrastructure
  • Determining a source of renewable energy to feed the project
  • Examination of the existing grid connection
  • Collection and processing of historical wind, solar and electricity pricing data
  • Examination of local, state, and federal regulatory requirements
  • Development of initial Superhybrid™ configuration

Adjusting the variety of variables within AESOP allows engineers to optimise a project to desired specifications. Variables that can be adjusted include, but are not limited to, storage, charging and electricity generation rates, incoming energy sources (wind, solar), and hydrogen production and storage. There are over 80 other accessible settings and variables that need to be considered in setting up a digital twin — AESOP can provide suitable defaults for most of these settings and as the refinement continues these too can be adjusted where necessary.

The decision to include a hydrogen production plant as a device to improve electricity supply resilience is somewhat counterintuitive. By adding more hydrogen to the project, it builds resilience, leverages increased renewable energy supply, provides more energy storage, and increases overall revenues. Ultimately, AESOP’s decision-based matrix is directed to prioritise maximising profits on the tradeable portion of its energy and as such allows the outcome of any simulation to take calculated and decisive steps that result in optimal profit, whilst adhering to project scope specifications.

AESOP supports pumped hydro, large-scale batteries, CAES, gravity storage and flow batteries. The innovative solution of incorporating AESOP with multiple green technologies including wind, solar and hydrogen production is what we call a Superhybrid™. The integration of such technologies requires unique decision-making to develop cohesive operations that best harness the capabilities of each component within the system to produce clean energy 24 hours in a day and 365 days of the year.

The integration of AESOP is a vital component that works to simultaneously manage the numerous processes within the Superhybrid. AESOP works by applying 33 specific optimisations, to effectively distribute the incoming energy to different parts of the system within the Superhybrid to ultimately meet contractual energy requirements whilst in turn maximising revenue through opportunistic trading within any electricity market.

An untold story about nuclear power

There’s been lots of discussion lately about nuclear power and its role in a future Australian grid. In a recent Investor Q&A Webinar for our equity crowdfunding campaign on Birchal, we were asked if we see nuclear power as a threat to our Superhybrid™ business model. That question inspired me to write this blog.  


Our story so far

The first tender shoots of the idea for this company started when I was living in a sustainable community. The community needed energy storage and I started looking at how that might be done. First I envisaged a micro pumped hydro station. However, the more I explored these ideas, the bigger things became and the possibilities of what could be achieved increased. It soon became clear that I needed a company with like-minded individuals to carry this forward, and so Sunshine Hydro was born.
