Mission Statement
1. To conserve and protect Toronto's eastern beaches and the Scarborough Bluffs from being unnecessarily desecrated.

2. To enlighten the general public of the pros and cons of industrial size wind turbines.

3. To unravel the politics behind the industrialization of Toronto's waterfront.

Helimax Report 2008 Highlights

Analysis of Future Offshore Wind Farm Development in Ontario
Prepared for Ontario Power Authority by Helimax Energy Inc. April 2008


- to reflect a sensible and rational site selection process.

- place 64 offshore sites in Great Lakes

- parameters - wind speed, development complexity, social and environmental factors and presence of infrastructure to establish the most favourable sites

- 9 sites in Lake Ontario (not evaluated -seabed properties and icing conditions, visual impact, social acceptability and economic viability)

- Social Acceptability - concerns on personal enjoyment and recreation (viewscapes, aesthetic issues and noise) property values and avifauna (the bird life of a district)

- no offshore project in the world faces comparable ice conditions to those of the Great Lakes re: harsh winters, enclosed areas (lakes) with weak currents.

- all factors; include a geotechnical survey (flora, fauna and fish surveys, a detailed noise impact assessment, a detailed wind resource study)

- distances 1-3 km. will appear prominent on the landscape (less favourable)


- offshore costs - 30-70% more than onshore wind farms (hardware and software)

- O & M costs 2.3 to 3.1 cents per KWH offshore vs. 1.8 to 2 cents per KWH onshore

- 2-3 ½ million dollars per meg. Watt plus learning curve, turbine supply, engineering experience

- civil works and interconnection approx. 10 times more costs than onshore

- additional protection against a fresh water or saline environment - thus turbines design must be more robust, lower supply demand than of offshore turbines add premium costs, ice formation require heavier foundation designs

- 4 million dollars per MW for hardware, plus maintenance significantly more costly and time consuming thus may trigger significant revenue losses.

- offshore experience, less available levels, longer wait times for spare parts, crew and equipment, inclement weather and longer repair times due to the environment.

- "Project owners and manufactures can be reluctant to share their experience."

Ecological reasons not to locate wind farm at Scarborough Bluffs

Environmental Constraints

- areas of natural interest (Scarborough Bluffs)

- environmentally sensitive areas (Fisheries Dept.)

- national parks

- natural wildlife areas

- national heritage values areas

- provincial parks (conservation reserves)

- significant ecological areas

- Oak Ridge Moraine

- Niagara Escarpment

Ecological Concerns

- lake bed disturbances

- aquatic life effects (fish spawning)

- zebra muscle habitats

- migratory bird path

- butterflies

- bats

- lesser species

- 12,000 year geological site with flourishing wildlife habitats

- environmental degradation will impact the natural quality of life for all species
