OBSERVATION
Given a choice between protecting the environment and impact on their Pocketbook, the majority of people will opt
for protecting their Pocketbook
Demand and Supply - A key QuestionDemand and Supply - A key Question
When will the Demand for Energy exceed the Conventional Supply?
The likely result will be Increases in the Price of Energy and Instability in that Price
The timing of this is very uncertain but it will happen

What will fill the Gap??
Filling the Gap - 2 SolutionsFilling the Gap - 2 Solutions
•Increased use of Nuclear Energy
•Renewable Energy Sources•Solar•Wind•Tidal•Biofuel derived from biomass•Geothermal•Wave•Small Hydro (Run of River)•Large Hydro
Properties of Renewable EnergyProperties of Renewable Energy
•Secure•A local energy source
•Environmentally Benign
•Inexhaustible
•But it is either intermittent or strongly location dependent or both

“Grid Parity” – The Holy Grail“Grid Parity” – The Holy Grail
•What is “Grid Parity”?•Equality of the renewable energy price per kilowatt-hour (kWh) with the currently accepted kWh price from the grid
12
Getting to “Grid Parity”Challenges
Getting to “Grid Parity”Challenges
•Bridging the current cost differential•Renewable energy incentives
•Generation of firm, dispatchable energy from renewable sources
•Creation of renewable energy dominated supply systems and subsystems
•Integration of renewables into existing energy systems and managing the transition
13
Getting to “Grid Parity”Solar Energy System Cost & kWh
Price
Getting to “Grid Parity”Solar Energy System Cost & kWh
Price
•Fuel is free! – Enhances price stability
•Large up-front investment, amortized over a defined time period
•Kilowatt-hour price is driven by the cost of amortizing the capital investment combined with the cost of operation and maintenance.
14
Getting to “Grid Parity” - TechnologyGetting to “Grid Parity” - Technology
•The technology must:•Maximize the number of kilowatt-hours generated annually per unit of capital invested.•This is the key performance parameter
•Produce the rated power over the amortization period and beyond.
•Have low maintenance and operating costs.
Getting to “Grid Parity”Bridging the cost gap
Getting to “Grid Parity”Bridging the cost gap
•Incentives (that reduce to zero over time)•Performance-based – Incentivizes performance improvement
•Capital rebate – Leads to commoditization – only price matters
•Tax-based•Others
16
Performance-Based Incentives
(Example: Feed-in-Tariff)
Performance-Based Incentives
(Example: Feed-in-Tariff)
•Guarantees a stable price environment and a stable return on investment (~8%) for a stated period (typically 20 years)
•Attracts private capital into the process of realizing a mature renewable energy industry by creating a stable and realistic pricing environment.
•Motivates renewable energy companies to innovate and discover ways to improve the number of kWh per annum per unit of invested capital in order to remain competitive. (Performance counts)
•Is an investment in future energy price stability•Reduces the time to reach grid parity.
•Money can be made doing all the right things to get there.17

Renewable Energy Sources are either intermittent or strongly location
dependent or both.
How can we create a system that can generate FIRM renewable power
ANYWHERE?

Renewables in the Mainstream
Creating the Infrastructure
•This is a very large undertaking•The structure will be very different from what we have today
•The design is highly location dependent•It will require much innovation and creativity•It will take much time
• Time that we may not have much of
•IT IS TIME WE TOOK MAINSTREAM RENEWABLE SYSTEM ARCHITECTURE SERIOUSLY
