Distributed Energy Solutions

The Challenges

Some energy users are connected to unreliable utility grids and, in order to support their electricity needs, they have historically utilised their own conventional power generation units.  These facilities could have been Coal, Heavy Fuel Oil (HFO), Diesel, or Gas-powered engines or turbines connected to electrical generators and/or heating systems.

Unconnected users have had no choice historically and had to rely on their own conventional power generation units.

The cost of carbon-based fuels is based on the particular location and any logistical constraints to obtain them economically and reliably.  There is a different carbon footprint for each type of conventional fuel and many users are evaluating what they can do to reduce emissions.

As part of the Energy Transition, many users will have (or plan to have) and increased use of Renewables in their Energy Mix.

Some Solutions from Stellae Energy

Distributed Energy Solutions with Renewables can include Solar PV, Wind, and Geothermal Energy in facilities close to the users

Hybrid solutions combined with existing conventional power generation are being adopted by many energy users.  The choice of these energy sources would typically be based on their availability and suitability for a particular location;

Energy Storage Systems are essential to provide stability and resilience.  Short duration (i.e. Li-on or LiFePo) as well as long duration ESS (i.e. Redox Flow or Hydrogen) systems are needed;

Hybrid Microgrids (either unconnected or connected to a utility grid) using multiple sources of energy including Renewables are one of the best solutions to provide both the reliability and sustainability needed;

Stand-alone Power Systems (SPS) are another good scalable solution, particularly for remote residential, commercial, or smaller industrial users. These modular steel containerised units provide conventional diesel power generators for back-up electricity, Battery Energy Storage Systems (BESS), inverters, and switchgear.

Externally they would have interconnected Solar PV and or Wind Turbines to provide the main energy source.  They would reduce carbon footprints and improve resilience for many remote users.
