2. Our mission a sustainable global future.
SEN defines Sustainable Energy as energy that is renewable within a human lifetime and can be produced safely and equitably for all time with minimal impact on the environment and future inhabitants.
I’d like to introduce you to Sustainable Energy Now (SEN as we call ourselves) –
Our mission is to promote the uptake of renewable energy – via practical and affordable strategies so that it can help us reach a sustainable energy future. Setting a good example of what can be done, will encourage other nations to do so also. 2

3. Background
Existing renewable energy software is useful but SEN's SIREN and PowerBalances solution offer further capabilities
Features:
Rapid renewable scenario generation with costs
Easily cater for multiple renewable energy stations and technologies
NASA derived weather data, US NREL electricity generation models
Example of local transmission network models & demand data (SWIS) 
Balances generation and storage with demand
In-house expertise to model and provide development scenario cases 3

4. SIREN Toolkit Process Flow4

5. 09/23/16
The SIREN Model
Sophisticated computer model with simple user interface
Users explore potential location and scale of renewable energy sources (stations, storage, transmission) to meet electricity demand
Can be based upon existing network
Enables rapid development of renewable energy scenarios using robust models 5 5

6. Map overlay "as-is" Network6

7. Weather affects generation
09/23/16
Weather affects generation
Weather data that reflects actual weather conditions of the past enables any model to better map actual load demand with “supply”
For example, hot weather increases air conditioning load
NASA MERRA-2* data
(~ 55km x 0-69km)
A source for worldwide solar and wind data
* Modern-Era Retrospective analysis for Research and Applications, Version 2 7 7

8. Place and size Stations
Click to add Station
Simple interface to specify Station details
Connects to grid network
Save & reload Scenarios

9. Model Power generation
09/23/16
Model Power generation
System Advisor Model (SAM) models from US National Renewable Energy Laboratory (NREL)
Run SAM model for each station and produce combined result
Match generation to Load 9

10. How does it compare?

11. How does it compare?
Validated SAM calculated generation with actual generation
(Average correlations for 2007 to 2015 vary from 0.70 to 0.77)
Validates use of US NREL SAM models and NASA MERRA-2 data
Correlation of actual generation with calculated gives confidence to use this approach

12. Scale to Requirements

13. Broad capability using public data
Data sources are publicly available
Models – NREL SAM
Maps – OpenStreet Map (or MapQuest, …)
Weather – NASA MERRA-2
Network – Location/area dependent
Developed to support any geographic area

14. Identifying Shortfalls?

15. What is PowerBalance? What does it do?
Programmed Excel spreadsheet templates for scenario types
What does it do?
Quantifies and costs dispatchable energy generation, storage and CO2 emissions
Balances power with load for the 8,760 hours of the year
Enables a complete a costed renewable energy scenario for the particular grid or island
