Remote communities rely heavily on fossil fuel for electricity generation. Industries, First Nations, islanders, and defense departments are now integrating renewable energy into their remote systems to save fuel. Closer to urban centres, electric utilities are testing battery storage to reduce outage time and provide other grid services.
Challenge: Sizing batteries and solar with diesel
When it comes to microgrid design, multiple objectives can be pursued. Choosing the right renewable energy size to save fuel, the right battery size to pick-up the load, and the right location for automated grid points is of paramount importance. Changing load profiles and extreme weather conditions need to be simulated properly for meeting fuel saving or reliability target of your investment.
Each microgrid is unique, just as your business and customers are unique. A well-planned project requires technical, economic, and customer engagement that fosters local acceptance and drives long-term economic benefits. We offer:
- A multi-year planning horizon;
- Distribution network load and outage modelling;
- Battery sizing for optimal outage or peak reduction;
- Solar sizing for optimal fuel saving;
- Voltage regulation schemes with smart inverters, and;
- Protection and system stability validation.
Smart home technologies to the rescueMicrogrid design can also be expanded to include demand-side technologies. Customer’s storage, smart thermostats and water heaters can be managed by the operator when the system is at stress. We plan demand-side and load management investments for microgrid developers and energy services companies. We offer:
- The identification of the best customer technologies at the lowest price;
- The preparation of customer offers (incentives and rates);
- The definition of load management schemes, and;
- The revenue impact calculation.
