Overview Power Systems

The Legacy Power Systems: The Emerging Power System:

➢ Consumers are installing solar PV, battery storage and microgrids

▪ Reducing environmental impacts.

▪ Sell their excess DER power back to the grid.

Source: online

➢ Energy Generation

➢ Energy Transmission

➢ Energy Distribution

➢ Deliver to the Consumers

Why DERiM Solution

As DER sites are growing..

➢ Developers and contractors to identify potential

sites for DER’s.

➢ Distribution service providers need to provide

necessary information to DER’s.

➢ Energy Efficiency (EE) and demand response (DR)

➢ Improve the Green Energy.

➢ Need proper utility Regulations.

• Rooftop and community-scale solar PV.

• Distributed battery storage.

• Natural gas-powered microgrids.

• Energy efficiency and demand response.
