GRCA Inks Deal With Ontario Power Authority, Dam Spending Increased & Tree Plantings!

Grand River Conservation Authority has agreed to sign a 20-year contract with the Ontario Power Authority for power produced at the Shand and Conestogo dams.

The hydroelectric contract initiative allows hydro producers to sign a long-term agreement at a rate of 6.9 cents per kilowatt hour in the base year 2009. Each year the price will be adjusted based on the Consumer Price Index. Currently, power from Conestogo Dam is sold under a contract that expires in September 2011 with the rate of 6.01 cents per kilowatt hour.

A 20-year contract will provide a stable revenue source for the GRCA. Any increase in the plant’s capacity would be eligible for revenue under a different program geared to encourage new sources of electric power at a rate of 13 cents per kilowatt hour. In 2010, the GRCA’s hydro revenue is projected at $364,000, compared to $220,000 under the existing terms of sale.

In other GRCA related news, the cost of work underway at the Conestogo Dam has increased from $2.8 million to $3.1 million.

The project began in July 2009 and is expected to be completed by the end of this year. Work involves upgrades to the stilling basin, which is the area immediately downstream of dam gates. Concrete walls and energy dissipation blocks are designed to calm the water after it surges through the gates.

During the project, it was also discovered that a portion of the south wing wall had poor quality concrete without enough strength to support the new new construction. Extra work will be required on this part of the wall.

Another piece of news from GRCA includes the planting 379,000 trees in 2010. Four different companies have been awarded contracts with a total value of $176,000.

The GRCA carries out numerous tree planting projects on both private and GRCA-owned property each spring. The cost of these plantings has increased over the last few years to the extent that it is necessary to put the planting contract out to public tender. The contract for machine planting throughout the watershed and hand planting of trees in the north part of the watershed will be done by Tree Logic for $83,103.88. Hand planting of seedlings in the south and saplings throughout the watershed will be carried out by Wilderness Vegetative Management for $76,000. Curb Appeal will plant seedlings and saplings on two GRCA-owned properties for a value of $11,000, while Great Lakes Woods Ltd. will plant seedlings in plastic mulch for close to $6,000.
