Hydroelectric

Facility

How much power can be generated?

h * Q * 85% / 11.8 = kilowatts capacity

kilowatts * Days of Operation * 24 = kwh

How much money can be generated?

Kwh * $.06 = $ per year generated

How much financing can that fund?

$ per year generated – annual costs = payment capacity

6% financing over 20 years

How much to build the facility?

Pipe costs, building, turbine-generator-switch

How close to utility for interconnection?

Do you know what FERC means?

Do you know anyone at your state PUC?

What is the zoning of your potential site?

Does this thing generate positive cashflow?

Putting the Financial Pieces Together At 10,000’

Any water conservation?

Conserved water for instream or additional lands to irrigate

Any O&M costs eliminated?

Any cost savings to someone else?

Pressurized water to patrons that reduces pumping

No need for bridges on new road being planned

Any benefits to someone else?

Piped waterway now creates opportunity for trails

Easement reduction provides more developable land

Identify Other Benefits

• 2.5 Miles – Main Irrigation Canal

• 9’ Steel Pipe

• 20 cfs Conserved Water Savings

• 3.5 MW Generating Capacity

• 5 MW built capacity

• $24 MM Project Costs

• Multiple Benefits & Beneficiaries,

& Funding Sources

• Capability to pipe upstream 4

miles and add 4 MW of power

• Each mile of additional pipe

generates 10 cfs for instream

It’s all about financial rate of return

Rate of return expectations higher than for municipal entity

Income taxes & property taxes

Incentives available to private party – PTCs and depreciation

Contract and performance driven
