What are primary power delivery challenges you are facing?
Schneider Electric is the largest supplier of medium and low voltage systems in the world.
Our top campus customers are data centers, health care, and other critical power campuses.
Out top utility customers are N.America’s IOUs.
The primary challenge is 2 hours of outages per year, vs 1 -2 min in other advanced economies
How do MG address those challenges?
Traditional and advanced microgrids are seen as the primary vehicle for resiliency, energy reliability and energy security
What are the major technical gaps preventing adoption?
Systems integration of switching, grounding and protection, and controls/optimization for brown fields
We don’t think there are insurmountable challenges, just making MG more repeatable

What is a Microgrid?
An integrated energy system consisting of interconnected loads and distributed energy resources…
…which can be controlled as a single entity operating in parallel with the grid and/or in an intentional islanded mode.

Businesses and Utilities will seize new, unique opportunities to
differentiate goods and services through intelligent infrastructure. The traditional approach is no longer adequate - models will be developed to
create new value for businesses and utilities to benefit from the new energy economy.
As alternative means of producing and distributing energy becomes
commercially viable…
Distributed generation, grid parity, aging infrastructure, climate change…
Increasing distributed generation to integrate with the grid – including renewables
Why Microgrids? Why Now?Energy trends
Climate change effects are more and more visible, new political trends (COP 21 Paris)
Grid parity is a reality

o Utility generation mix is changing, led by natural gas, wind and solar.
o About 10% of the US grid is based on DER, with solar representing the fastest growing DER and cogen
o Many utilities are buying Solar Integrators, and will increasingly use battery energy storage and generators as “anchor resources to make this DER work without the grid
o SE is an expert at adapting switching, control, protection and grounding systems for DER to “island.”

Key Trends Declining Cost of Solar The Natural Gas Boom Affordability of Energy Storage
Schneider Electric
Solar power has become a cost effective tool for lowering an organization’s energy bill
Solar generation is often at peak production capacity when electricity prices and demand are the highest
North America, gas is $4.5 MMBtu vs. $12 - $16 in Europe and Japan*
It will stay inexpensive due to horizontal fracking
The cost of lithium ion-based storage systems are expected to decrease dramatically over the next few years
The technology is becoming a key enabler for cost savings

• Shifting the electrical consumption from on peak hour to off peak hour, while ensuring the comfort of the occupant• Example 1: charging an energy storage
system during off peak period and discharging it during on peak period
• Example 2: consuming electricity with a HVAC during off peak period (pre heating or pre cooling) and reducing its electrical consumption during peak period
Use Case:Tariff management – Load shifting
Page 40Confidential Property of Schneider Electric |
Energy bill optimization
• Optimizing DER Start/Stop based on electricity tariff and building occupancy• Example 1: starting and stopping an
HVAC system at the right time during the day for ensuring the comfort of the building occupant and avoiding wasting energy
Use Case:Tariff management – Optimum start/stop
Page 41Confidential Property of Schneider Electric |
Energy savings and energy bill optimization
• Optimizing when to charge and discharge your energy storage device based on electricity tariff • Example 1: charge batteries during
low tariff periods • Example 2: discharge batteries
when tariffs are high
Use Case:Tariff management – Battery Integration
Page 42Confidential Property of Schneider Electric |
Discharge at high price periods
Charge at low price periods
• Shaving the consumption peak in order to reduce demand charge or to avoid paying penalties• Example 1: shedding an HVAC during a peak
consumption period, while ensuring the comfort of the building occupant
• Example 2: discharging an energy storage system or turning on a distributed generation asset during a peak consumption period
Use Case:Demand charge – Peak shaving
Page 43Confidential Property of Schneider Electric |
Energy bill optimization
• Consume energy produced locally first, import energy second• Example 1: charging an energy
storage system with the extra amount of electricity produced by a PV system and consuming it later during the day
Use Case:Self-consumption
Page 44Confidential Property of Schneider Electric |
Be greener and optimize your energy bill
• Performing load curtailment following a Demand Response request
• Can be performed as demo “manually” or via OPEN ADR with a utility / commercial aggregator who can bid on the energy market• Example 1: answering and performing
automatically Demand Response requests (for instance load curtailment with a HVAC or an energy storage system) sent by a commercial aggregator through OPEN ADR
Use Case:Demand Response – Load curtailment
