SMALL HYDRO ENERGY
The installation of most of very low head sites is technically feasible, but civil works give rise to high costs, resulting to economically enviable projects. To solve this problem, one must design a new machine using a completely different philosophy to equip such sites: the small hydro power system.
The study of current turbines reveals that they were all invented on the basis of a poor understanding of hydrodynamics, and a consequent false premise.
The new damless development of a submerged helical pathway is capable of extracting high energy from low head sites at very low cost because of a physics phenomenon, called repulsion energy, which speeds up the current at the extremity of the curves. This is an exciting breakthrough in green energy; it is modular, relatively easy to install and highly scalable.
The secret is in the natural motion of the water, which is a vortex. Water reduces resistance by curving more and more inwards thereby avoiding the confrontational resistance of straight motion. Nature has no use for the straight line: think of the water that leaves your bathtub; give it a twirl and see what happens.
The threshold velocity required to energize a turbine in fast water is 3.1 m/sec. The vast majority of river/ocean currents in the Canada and United States are slower than 3 m/sec. The HUG taps into a vast new source of clean and renewable energy of water currents as slow as 2 m/sec. previously off limits to conventional turbine technology. Even if the flow is less than 2 m/sec, the HUG introduces the Energy Body to make a difference.
Electricity Energy Costs
- Median cost of base load power: gas, coal and atomic plants: $0.10/kWh (2015)
- Rooftop Solar power: $0.16/kWh to $0.31/kWh: in Spain and Belgium respectively.
- Coal plants could be $0.17/kWh if carbon emissions will be accounted.
- Solar Energy: $0.20/kWh and $0.10/kWh before 2025
- Advanced clean-coal plants cost about 11 cents per kWh, the same as nuclear.
- Advanced natural gas-burning plants come in at just 6.3 cents per kWh: add 70% for carbon emission costs: $0.107 /kWh
Wind Energy: On Jan. 1 the federal production tax credit on wind investments expires. For the past 20 years the credit has offset about 30% of the cost of wind turbines. The final true cost is $0.15/kWh.
Ratepayers are paying about $8.5 billion more this year for electricity from wind than they would have paid if it were gas-fired power. That amount doesn’t even include the cost of the direct federal subsidies but this money subsidizes a less efficient, more expensive technology: $8.5 billion that could otherwise be invested in other electricity solutions.
Significant hydropower potential remains unexploited. The technical potential is some 4.8 times greater than today’s electricity generation. Typical emerging small hydro technologies include: low head (<15 m) and very low head (< 5 m) power generation technology
- Micro Hydro (< 2 MW) and Small Hydro Investments (Up to 50 MW): $1,200 to $6,000 per installed kW: 75% of costs are site specific. The total installed costs for large-scale hydropower projects typically range from a low of USD 1,000/kW to around USD 3,500/kW.
- Nuclear Reactors: In South Carolina, power company Scana and its partners are investing about $11 billion to construct two 1,100 mw nuclear reactors: $5000 per kW: a very high upfront cost.
- Breakdown of Costs of Small Hydro:
Typical Small Hydro: 12.5 MW x $6,000,000 = $75,000,000
- Equipment: 18%
- Electrical Connections 2%
- Infrastructure 73%
- Planning 4%
- Other Installation Costs 3%
HUG Costs: 11 MW: $1,286,000
- Equipment: 62%
- Electrical Connections 4%
- Infrastructure 4%
- Planning 15%
- Other Installation Costs 15%
Total Costs::11 MW: $117/kW $0.015/kWh @ 90% of Usage

Why so low? The Infrastructure Cost is not 73%.
Levelized cost of electricity (Discounted lifetime costs divided by discounted lifetime generation):
The IEA assumes 2.2 % for large hydropower and 2.2 % t3 % for smaller projects, with a global average of around 2.5 % (IEA, 2010c). Other studies (EREC/Greenpeace, 2010 and Krewitt, 2009) indicate that fixed O&M costs represent 4 % of the total capital cost.
The difference between a 3% discount rate and a 10 % discount rate is very significant, with the LCOE increasing by between 85 % and 90 % as the discount rate increases from 3 % to 10 %.
The levelised cost of electricity (LC) for hydropower refurbishments and upgrades ranges from as low as USD 0.01/kWh for additional capacity at an existing hydropower project to around USD 0.05/kWh for a more expensive upgrade project assuming a 10% cost of capital.
According to the federal Energy Information Administration, the “levelized cost” of new wind power (including capital and operating costs) is 8.2 cents per kWh. Most calculations of the cost of wind power do not take into account the costs per kWh of keeping fossil plants on standby or running at reduced loads. But they should, because it is a real cost of adding clean, green, wind power to the grid.
With 8.2 cents per kWh, reflecting total installation costs of $2,000 per kw of capacity.
- Then account for an assumed 30-year lifespan for the turbines (optimistic), which increases the cost to 9.3 cents per kwh.
- Then add the effect of subsidies allowing accelerated depreciation for wind investments you get 10.1 cents.
- Add the costs of keeping gas-fired plants available, but running at reduced capacity, to balance the variable performance of wind — 1.7 cents.
- Extra fuel for those plants adds another 0.6 cents.
- Finally, tack on 2.7 cents for new transmission line investments needed to get new wind power to market.
This adds up to $0.15/kWh. Ontario pays $0.11 – $0.135/kWh for wind power. Compare Ontario Hydro rates to: 5.6 cents in Quebec and 7.3 cents in Manitoba

RING of FIRE The Ring of Fire Potential will come down to one factor, which will make or break any prospects: Hydro Electricity. Enter the HUG!
LABRADOR ENERGY POTENTIAL Any new technology leads to new growth opportunities: HUG is a Patented Energy System that will literally change the face of our world as we know it.
MOBILE HUG: The HUG development is an exciting breakthrough in green energy. Small batches of HUG turbines can be installed with only a short period of 12 to 18 months between investment in the technology and the time when revenue starts to flow: it is modular, relatively easy to install and highly scalable.
PRE-FABRICATED HUG Standardized pre-fabricated modules should make it possible to order this new product as a “power plant kit” just like ordering from a catalog. The HUG power plant uses standardized parts, so no custom engineering is necessary. A one-size-fits-all pathway could be ordered.
Why is the HUG Frictionless? When we direct the water to flow at its natural mode, it hugs the inner wall. This kind of vortex motion tends to accelerate and contract the stream of water. The less collisions improves the flow, i.e. the better ordered and more dense the flow will be. The net result is that the velocity of the flow in the HUG is four to five times faster than the river velocity.
