Smart Grid
“The smart grid is not a single technology, but rather a broad
range of interconnected, inter-operable technologies –
including distributed generation, energy storage, wireless sensor
networks, software and computing – that can give customers
the ability to reduce costs, improve efficiency, and
enhance the environment that we live in by several means. “
Mike Niggli, President and COO of SDG&E
Smart Grid Workforce
A broad range of interconnected, inter-operable PEOPLE –
including experts in Engineering, IT, Telecommunications, Field
Services, Data Analytics, Customer Service, Innovation,
Marketing, Project Management… that can give customers the
ability to reduce costs, improve efficiency, and enhance
the environment that we live in by several means.
SDG&E’s Smart Grid Roadmap
• SDG&E’s roadmap includes smart grid investments in 9 programs:

Smart Grid Deployment Plan Objectives
Engage customers and other stakeholders to create a Smart Grid Deployment Plan that reflects the region’s priorities and values – not just those of the utility.
Align the organization so that it can continue the cultural change necessary to create the Utility of the Future.
Analyze a wide range of potential projects oriented toward “smart” technologies and services – prioritizing cost vs. benefits, both financial and societal.
Comply with CPUC decisions, state and federal policy
SB 17 and D.10-06-047

Methodology
Presents a comprehensive plan that includes 64 projects in 9 programs
The plan is not a request for funding – it is a “policy guide for future investments”
8 officers, 18 directors, 150+ managers and staff helped develop the plan
Two-Way dialogue with 25+ stakeholder groups
Aligned to SDG&E Strategic Plan
Collaborated with the Environmental Defense Fund to value environmental benefits
Partnering with the Office of the Information and Privacy Commissioner of Ontario on the implementation of customer privacy policies (DPP)

• Paperwork
• Manual processes
• Labor intensive
• Software systems are not fully integrated
• Unplanned outages are reported by customers
• Limited ability for specialized reports
• Near real time data
• Automated process
• Integration with more systems
• Faster outage restoration times
• Better management of customer expectations
• System generated reports
• System generated switching plans

Research, Development & Demonstration: SDG&E Borrego Springs Microgrid Project
Project
Description
In cooperation with the US Department of Energy and the California Energy Commission,
SDG&E and 10 public and private sector partners will develop a “microgrid” project - a small
version of its electric grid which takes advantage of local distributed energy resources and
state-of-the-art controls to enhance grid operations – to achieve a >15% reduction in feeder
peak load and improve system reliability.
Current
Status
•Site Selection complete – Borrego Springs
•Finalizing system requirements and high level design
•Developing customer communication plan
•Collaborating with environmental agencies to satisfy permitting requirements
