Micro-grid installations might soon become a fixture in neighbourhoods or new housing developments, especially as the prices for storage are forecasted to drop in costs. Talks about increasing costs for existing infrastructure of the traditional grid (as less traditional power is used by the consumer) helps to build the business case for solar PV plus energy storage nanogrids. These focus on distributed solar PV installations in behind-the-meter building-level applications for residential and commercial customers. Extracting the greatest value from solar PV in the absence of subsidy will require linking this variable distributed generation (DG) to a battery. As such, pairing solar PV with energy storage in a distributed fashion will soon emerge as the most economical way to successfully incorporate distributed energy resources into today’s market landscape.
