The document discusses clean energy microgrids, which are small-scale power grids that can disconnect from the traditional grid and operate autonomously. It provides examples of microgrids at the University of Texas and other locations. Microgrids are owned by customers or third parties and can improve energy reliability and profitability while reducing emissions. The document outlines reasons to implement microgrids including improving asset utilization, avoiding rising utility costs, and increasing control during outages. It also discusses some barriers to microgrid adoption like regulatory reforms and the need for standardization.

2. What is a Microgrid?
Controls load and generation onsite
Includes distribution wires
Connects or disconnects (island) from
central grid with black-start capability
Provides energy 24/7, 365 days a year

5. The University of Texas microgrid
140MW
100 percent of power
heating and cooling to 150 campus buildings
20 million square feet
Operating 40 years with 99.9998% reliability

7. Why microgrids?
1. Improves asset profitability
2. Avoids rising costs of main grid
3. Meets rising peak demand at lower cost
4. Control during unplanned outages
5. Reduces carbon emissions

8. 1. Improves property profitability
Continue to generate revenue regardless of
whether the main grid is operating or not
Utility costs available for resale rather than as a
pass through cost paid to utility

10. 3. Meets rising peak demand
Defers costly and
lengthy
transmission
upgrades
Increases reserve
margins

12. 4. Greater control of supply and costs
Severe weather such as Superstorm Sandy
leading cause of power outages in USA
Losses risen to $200 billion per year in the
last decade, globally
Unplanned outages also due to under
investment, lack of maintenance, substation
and transmission line equipment failures

15. 5. Reduces carbon emissions
Cost effectively lowers carbon emissions by
using waste heat, demand response, solar,
wind, fuel cells and batteries
Improved access to climate change financing,
meets national environmental laws and
emissions reduction targets

17. Can microgrids operate legally?
South Carolina state
has jurisdiction over
the sale of power
from rooftop solar
panels to a host
Connecticut allows
microgrids to sell
across power across
public streets

18. Why Israel should get onboard
1,437 microgrids worldwide, 13 GW
$40 billion annually by 2020, up from $10 billion
in 2013
Clean energy investment in China, Africa, the US,
Latin America and India $328.9bn in 2015

20. What’s the ROI of microgrids?
20
Pay for themselves due to cost savings
Avoidance of transmission upgrade and
Continual operations
Texas U Microgrid, Princeton U MG and many
others have achieved net savings

21. Timing is right
Bankable energy storage (batteries)
Solar PV costs reduced by 95% over 10 years
Improved microgrid power control software (IoT)
Operations and regulations simplified
21

22. 22

23. Barriers to exponential growth
Reform energy, capacity and ancillary markets
Allowed to serve as their own balancing
authority when in island mode
Provide compensation for congestion relief
Recognize value of black start capabilities
23

24. Opportunities for Israeli Companies
“it is more economically viable for a hybrid PV-CSP power
plant with Molten Salt storage to operate baseload in
comparison to hybrid PV-diesel” or PV-battery
This is true for Chile and South Africa, North Africa,
Australia, East Africa, India and China

reducing outage time by more than 98% at a cost
comparable to non-integrated baseline solutions
reducing emissions by more than 20% and
improving system energy efficiencies by more
than 20% by 2020.
