The Tiny Town Movement

Let's talk about making legal places for Tiny Homes. Tiny homes offer another way of addressing affordable housing and homelessness. These discussion areas provide a forum where we can develop the ideas and strategies that can make Tiny Towns a reality. To become part of the discussion simply Join the Association (it's Free) and then get into the conversation on topics that interest you.

The highest density pods are expected to have 10 tiny homes residing in them. The question becomes what are the potential power requirements for a pod? Below I have listed some anticipated power requirements for each tiny home, and what we will need to do is calculate the potential power requirements of each, to ensure that we produce and store enough power to support each pod operating off the regular power grid.

  • 12v lighting for inside and outside each house
  • fridge - full size, energy efficient
  • induction stove top, oven (the stove tops may be gas but best to plan for all electric)
  • microwave - plan 1,000W
  • coffee brewer
  • toaster
  • dishwasher - standard built-in
  • exhaust fans - bathroom, kitchen (range hood)
  • ceiling fan (living room)
  • a heat pump system
  • AC system
  • infrared heating panels
  • washer/dryer combo
  • on-demand hot water system (most likely gas, not sure if electric is an option)
  • computer
  • tv
  • audio system and speakers

These are the items I have identified that could be in a Tiny Home and require power. The next step is to add to the list any items I have overlooked and then identify average daily power requirements for each item to come up with a potential max per Tiny Home. Then we can figure out the requirements for a pod and determine the size of the solar/wind systems needed to generate the power required.

Note that comments can be added by everyone, are appreciated, but they are just comments. Board members should use the Submit Your Response form below with constructive information to build on this topic so that we can assemble the required information. Upcoming talks with Tesla could benefit with as much data available as possible.

An item popped up on my LinkedIn feed today about the initiatives funded by the Ontario Smart Grid Fund. I think we need to look into this and develop a proposal for the Smart Grid in our FirstTinyTown project. 

From the site:

Building the smart grid

The Smart Grid Fund is helping us modernize Ontario’s electricity distribution grids. The fund supports innovators to develop cutting-edge technologies that will make our systems run better and give customers more choice and control over their power use.

By using sensors, modern communications technology and powerful computer systems, a smart grid can:

  • make electricity grids more efficient, reliable and resilient
  • harness data to help customers and utility companies make decisions
  • make it easier for customers to use new technologies - like electric vehicles, rooftop solar generation or energy storage
  • allow customers to track and manage energy use
  • create savings on your bill

Types of projects

The Smart Grid Fund provides money to test, develop and launch the next generation of technologies that can turn Ontario’s electricity distribution systems into modern, digitally enabled grids.

We funded projects in the following categories:

  • proactive consumers - testing tools that households can use to directly manage how they use power (for example, home energy management systems)
  • data analytics - powerful software to analyze electricity systems and make them work better
  • electric vehicle integration - testing how to charge electric vehicles with minimal impact on electricity grids, while ensuring that owners have enough fuel in the tank
  • energy storage - exploring the benefits that energy storage offers when it’s connected to electricity grids and managed by intelligent control systems
  • grid automation - using new technologies powered by intelligent software to detect and automatically fix problems on electricity grids
  • microgrids - exploring the potential for combining renewable generation, energy storage, and intelligent controls to address system issues or give customers access to cleaner, more reliable power
  • building local capacity - creating Ontario-based centres of excellence focused on the domestic and global promotion of smart grid technologies and the local companies that design these technologies

This calculation is a bit higher than the above mentioned calculations. The higher is taken so as to meet any excess use per home. The Panel size and design has been taken into consideration for the acrage. Kindly, find the attachment for reference.

Hi 

In terms of calculations I have added a file stating most of the above mentioned demand and supply formulation. The maximum number of panels required could be upto 7 per home(in terms of maximum wattage).

The challege would be during the winter season, it would require atleast 8 hours of irradiance to have a backup for 24 hours for approximately 4000 watt hour energy. I have taken higher side of wattage. The backup can be complimented and compensated during winter by supplying power from the grid supply.

Thanks, Sayan. I have proposed to Paul Dowsett who is looking at designing the common area structure, that we plan for 120 x 300w panels for each Pod. When planning the battery storage, I feel that we should plan to have 50% more capacity than our calculations, at least in our first demonstration/test town. Through monitoring consumption, we can determine if more is needed or if less would be sufficient.
