Hybrid Energy Systems
CTP has a dedicated Hybrid team specialised in providing solutions for Hybrid Energy Projects. Our clients include developers, property owners, councils, mine sites, island resorts, manufacturers and universities. As of mid 2020, CTP has been a key technical partner in the deployment of over 10MWp of hybrid PV projects, which incorporate over 6.5MWh of energy storage and integration with numerous spinning generator systems.
Off-Grid – Microgrids
On-Grid – Dispatchable Power
On-Grid hybrid systems are grid connected and exchange energy with the wider electrical network. Embedding hybrid energy systems and controls allows access to new revenue streams such as demand response and energy arbitrage; lowering energy costs.
With the appropriate controls and equipment, On-Grid hybrid systems can be ‘islanded’ and can run independent from the grid.
Why Install a Hybrid Energy System?

|Participate in demand response|
|Reduce peak demand charges|
|Reduce diesel consumption|
|Energy arbitrage (Retail/wholesale)|
|Backup power supply|
|Improve power quality|
|Meet renewable/sustainable targets|
|Reduce diesel consumption|

Feasibility Studies & Approvals
Off-Grid: CTP has completed numerous assessments of hybrid PV, battery and spinning generator microgrid involving detailed modelling of energy flows, system operation and storage to determine the economic benefits of offsetting fossil fuel consumption with a combination of batteries and Solar PV. The ideal sizes and integration of the Solar PV and battery storage options can be assessed based on technical, environmental and financial limitations.
On-Grid: CTP has completed numerous hybrid energy studies in grid-connected scenarios to determine optimised capacities and costs for various combinations of PV, batteries, spinning generators and control systems. Studies involve analysis of tariffs, load & generation profiles, islanding & back-up power, network augmentation offset and interaction with demand response & ancillary service markets to determine ideal sizing and required equipment to achieve an innovative and practical solution. For on-grid hybrid energy systems, CTP will manage the complete grid connection processes with in-house expertise and software, having completed grid connection studies for a range of generating technologies up to 100MW in capacity.
Modelling: CTP has in-house microgrid modelling capability which is done with HOMER/HOMER Grid (microgrid simulation software) PVSyst (industry standard PV generation modelling software) and DIgSILENT PowerFactory (leading power system stability software). Where grid connection studies are required, CTP utilises in house software and engineers appropriate to the size of the plant and connection location, including:

Concept Design & Specifications
In order to progress a Hybrid Energy project the logical next step for many clients is to define the requirements in a concept design and set of specifications in order to seek quotes from the market / suppliers. CTP is experienced in preparing front end designs and specifications that realistically connect client requirements and the capabilities of what is a relatively new industry. CTP works closely with many of the leading vendors, has the delivery experience and depth of technical knowledge to be able to quickly direct a hybrid project towards a viable concept, avoiding too many iterations or rabbit holes.
