Challenges facing grid connected
renewables
• Old infrastructure – designed for one way transmission
• Limited control on loads
• Designed to meet peak demands

The New Challenges
Rapid growth in Micro generation
• Distributors are obligated to maintain operational voltages to customers
within prescribed ranges (+10% and –6% of nominal voltage).
• Small scale generation (up to 16 amps per phase) is installed and notified
latter*
• Generation profile does not match usage proposal
* Unless part of a muti-installation project such as a social housing or a community project including a number of properties situated close together

Demand profile
• Peak in demand in early evenings
• Peak in generation at noon (or
windy days)
• Solutions for this include
• Demand side management
• Energy storage

Outputs from the project
• Demonstration of the practical aspects of the technologies
• Batteries, communication and control
• Financial modelling to demonstrate the economic case for the approach
• Based on real data from pilot homes.
• Identifying wider financial benefits
• How does technology fit with existing infrastructure?
• How will DNOs be able to participate in the financial benefits?
