Ontario’s Energy Markets in 20 Years
Cleantech Business Forum
Ontario Environmental Industry Association (ONEIA) Workshop Presented by: David Teichroeb - Enbridge Inc. May 3, 2013

Enbridge’s Footprint
• Employ 10,000 in Canada & U.S.
• Largest liquid pipeline operation
• Natural gas transmission and Canada’s largest gas distributor
• Electricity transmission
• ~ $ 3 Billion in Green and Alternative energy
• Includes fuel cells, geothermal power, run of river hydro, heat to power, etc.
• More than 1300 MW of wind and solar assets operating or under construction
• Recent Investments include Hydrogenics and Temporal Power for electricity storage & Morgan Solar for CPV

Investing in Ontario Companies
Morgan Solar – Toronto, Ont. • Concentrating Solar Photovoltaic (CPV) – Sun tracking technology – Good potential for grid parity power costs
Hydrogenics, Mississauga, Ont. • Electricity Storage with Hydrogen – Power-to-Gas uses hydrogen electrolyzers for
bulk storage of surplus renewable power – Store renewable Hydrogen in natural gas grid
Temporal Power, Mississauga, Ont. • Flywheel Energy Storage – Flywheels enable correction of short-duration
power imbalances – Mechanical battery storing kinetic energy

Innovating for Smarter Energy Grids Energy Exchanges Between Silos
• Energy exchanges bring new economic, environmental , and operating flexibility to power grids
• Power to Gas converts renewable energy to hydrogen with electrolyzers
• Renewable gas back to power
Natural Gas 35%
Transport Fuels 36%
Electricity 19%
Other 10%

Gas to Power
5
Power to Gas; Seasonal Electricity Storage
• Off-Peak electricity to hydrogen with water electrolysis
• Blending of hydrogen in pipeline grids
• Store renewable gas in cavern or pipeline
• Blended gas to electricity at peak time / peak season • Alternative end-use as green heat or upgrading
Renewable Fuel to CCGT & Gas-Fired Distributed
Generation
Cavern Storage
PEM Electrolysis
Natural Gas Network

Flexibility of Power to Gas 1) converts surplus, non-emitting electricity to hydrogen with electrolyser, 2) bank energy in pipeline infrastructure, 3) transmit energy by pipeline, and 4)
economic discharge of renewables at the time and place it is needed

Combined Cycle Gas Turbine Generators
• More flexible planning for energy supply & transmission • Geographically distributed for grid stability, charging and discharging • Electricity storage with the single addition of electrolyzer
• all other infrastructure exists
