FAQ
A: CAES makes Ontario’s energy grid more efficient and resilient. CAES has the ability to power more than 624,000 homes for up to 8 hours a day using repurposed green energy. Harnessing renewable energy sources like wind and solar helps reduce our province’s reliance on non-clean sources which are subject to shortages.

A: While our national net zero ambition requires a reduction of emissions, individuals and businesses across Ontario will still need energy. CAES speaks to the former while delivering on the latter. The repurposed green energy that CAES will provide the grid reduces energy waste (by repurposing energy) and greenhouse gas emissions (by using emissions-free technology and reducing reliance on non-clean energy sources). The reduction in greenhouse gas emissions alone are equivalent to removing more than 328,000 cars from our roads.

A: By innovating existing technology in use in other locations (Germany, Alabama), Bedrock’s CAES is itself 100% emissions-free. The Bayfield and Stanley locations Bedrock uses to store green energy as compressed air utilize the unique geological characteristics of naturally-occurring porous rock reservoirs in Southwestern Ontario.
A: Bedrock’s CAES will have the capacity to power more than 624,000 homes for up to 8 hours a day using renewably-sourced energy. This will not only save ratepayers upwards of $150M per year, it will also create jobs and incentivize green energy solutions well into the future.
CAES: COMPRESSED AIR ENERGY STORAGE

INNOVATION.

Bedrock’s Compressed Air Energy Storage solution (CAES) will have the following impacts:x

FINANCIAL

Bedrock’s CAES will save Ontario ratepayers upwards of $150M, and promises to create hundreds of jobs in Ontario — all in support of a sustainable future. Repurposing surplus green energy will help stabilize energy prices for ratepayers.

ENVIRONMENTAL & INNOVATIVE

Our Bayfield and Stanley locations feature natural reservoirs, 500-1500m below ground, capable of storing enough compressed air at 1,176 PSI to power 624,000 homes across Ontario (approx. 520 Megawatts). The unique geology of these reservoirs can handle extremely high pressures and temperatures, and the technology used is tested and proven. With further innovations to existing CAES models however — ones that require natural gas to operate — Bedrock’s CAES solution is an emissions-free solution which puts Canada at the forefront of innovative green technology going into the future.
THE PROBLEM

How do we balance Ontario’s peak energy demands with the intermittent supply provided by various sources of renewable energy?

THE SOLUTION

1. Managing Ontario’s peak energy demands

Ontario’s homes and businesses need power to operate, and sufficient power is not always available to satisfy demand. In periods of both high and low demand, excess energy can be generated. In low-demand periods, this excess is simply related to how low the demand is, i.e. demand is lower than production. In high-demand periods, this excess is related to demand dropping while production is still at peak rates, i.e. production gets ramped up to deal with demand, but does not necessarily stop on a dime when demand drops.

2. Managing intermittent renewable energy supply

Ontario’s homes and businesses need power to operate, and sufficient power is not always available to satisfy demand. In periods of both high and low demand, excess energy can be generated. In low-demand periods, this excess is simply related to how low the demand is, i.e. demand is lower than production. In high-demand periods, this excess is related to demand dropping while production is still at peak rates, i.e. production gets ramped up to deal with demand, but does not necessarily stop on a dime when demand drops.

3. Lowering emissions on the way towards net-zero

The future will bring with it various challenges, many of which we are already starting to feel and face. Canada’s net zero emissions goals already require significant progress to be made with regards to our energy infrastructure as well as our energy innovation. CAES is a significant step in the right direction, and one that benefits all stakeholders and ratepayers in equal measure while also utilizing and safeguarding our natural environment.
