The line was built to improve transmission to the Niagara area partly designed to complete in time to support increased capacity at the Beck generating stations of Ontario Power Generation (OPG). The completion of a $1.5 billion tunnel project was to get more water to turbines, with an estimated increase in power generation of 1.6 terawatt-hours (TWh). The primary reason given by Hydro One, in 2005, for the "Niagara Reinforcement - Transmission Line Project was, "Facilitate new generation development in the Niagara Falls area." 
The need for that was apparent to all who read the Buffalo New in 2011, as it reported on the international agreement regulating the water usage from the Niagara river. Prior to the completion of the tunnel OPG was unable to utilize their full allotment of water for power generation and an agreement allowed the U.S. side to generate power with the unused quota.
The new tunnel will not change that amount, because the U.S. has been drawing off whatever amount of water Canada could not handle, up to the treaty limit. The U.S. used the water to generate power, and then sent half of it back to Canada, Kangas said. The rest of that power was taken by the U.S. as a rental fee. "The U.S. has had more capability to produce energy, but now with the new tunnel they (Ontario Power Generation) have the capacity to process that water," Kangas said. That arrangement has affected only about five percent of the water drawn, [OPG media relations manager Ted] Gruetzner said5% of the water drawn on the river equates to 10% of the Canadian allotment. In 2011, assuming OPG lost half the prospective income on 10% of the potential hydro output the cost was about $22 million a year.
When the tunnel project completed in March 2013, a strange thing didn't happen - the annual output from OPG's Niagara river units remained essentially flat.
Note the same relationship exists between the Moses Dam and Saunders Generation station at the other end of Lake Ontario - and there, once I adjusts for output discretely steered to Quebec's grid, the two side do generate the same levels of electricity.
$67.2 million is what 1.6 TWh collects at OPG's currently regulated rate for that output.
It's been 2 1/2 years - which would be ~$168 million, or half that if the U.S. side could use the water and paid back Ontario with half the generation. More likely it would be over half because while OPG may be entitled to half the output, it has no way to transmit that half regardless.
Call it $100 million and growing by $50 million each year.
$50 million a year.
This is 10 times the interest on the transmission line CTV reported on, which is conservative as OPG's spend was 15 times greater on its project.
There are other costs being rung up besides that incomplete transmission line and a tunnel project which hasn't noticeably increased generation, most notably the largest industrial wind turbines in the province will bestride the wireless towers - with new transmission being built to get that bottle-necked power out of the region. The new route is required because of the inability to complete the Niagara-Reinforcement line, which CTV reports Energy Minister Bob Chiarelli explaining as, "a dispute between two First Nations that needs to be resolved by the federal government.?
Perhaps the Minister and his Premier should consider advancing the resolution by ceasing to force ratepayers to throw money at the Six Nations territory where the dispute is. The wind turbines are being built adjacent to the wireless towers by the Niagara Region Wind Corporation - the project is only one of many industrial wind projects the Six Nations hold an interest in:
Niagara Region - 230 megawatts capacity (MW)and the solar interests:
Grand Renewable - 149 MW
Summerhaven - 124.4 MW
Port Dover and Nanticoke - 105 MW
Dufferin - 61.4 MW
Grand Valley - 40 MW MW
Gunn's Hill - 25 MW
Port Ryerse - 10
First Solar Walpole 20 MW
Grand Renewable 100 MW
Welland Ridge 10 MW
Norfolk 10 MW
Brandgate 8 MW

The Six Nations have these interests because developers get paid more for the output if the project is deemed to have aboriginal participation of at least 10%, the project received a higher rate in the feed-in tariff contract offers.
Assuming each of these projects has a 10% aboriginal interest (the minimum for the adder to apply), the added cost to Ontario ratepayers of Six Nations involvement totals over $6.7 million a year.
For 25 years.
The little Calendonia dispute "between two First Nations" has had a huge impact on Ontario's electricity ratepayers. CTV reports on $5 million in interest charges but I've demonstrated the costs on the public generation side are likely 10 times that, and then there's the additional $6.7 million Ontarians are obligated to pay for renewable power projects where those who prevented the Niagara reinforcement line reside.
$61.7 million each year.
If OPG's Niagara plant goes another decade without demonstrating the 1.6 TWh annual increase promised by the tunnelers, the political nonsense in this region will be as expensive as the gas plant scandals in the Toronto area.
As impolitic as it is to say so, perhaps there's something not quite right about race-based electricity procurement policies.
