NPPD:Who We Are

• Nebraska Public Power District was formed on Jan. 1, 1970 through the merger of:

— Consumers Public Power District — Platte Valley Public Power & Irrigation District — Nebraska Public Power System

• Nebraska’s largest electric generating utility

• Governed by an 11-member, popularly-elected Board of Directors

• Employ more than 2,000 people across the state

• Serve both retail and wholesale customers

• Integrated utility system, with: — Generation facilities — Transmission facilities — Distribution facilities

• Diverse mix of generation resources, which includes:

• 40 percent of our energy mix for native load is carbon-free

— Coal— Nuclear

— Hydroelectric— Wind

— Natural Gas— Diesel/Other

G140101

The Path ofElectricity

G140101

From the power plant, electric energy is delivered through a series of lines and substations where the voltage is

reduced to the proper level for end-use customers.

Criteria used to determine substation siting area:

These and additional criteria will be carried forward into the substation siting process.

What other criteria should NPPD consider? Which is most important to you?

Finalsubstationlocation

Criteria that will be used to determine final substation location:

Within general proximity to Cherry County and Western 345 kV transmission line

Minimize the need for additional transmission lines to connect substations

Constructable sites located within area

Locations outside communities

• Road access• Topography• Habitat/Environmental concerns• Ability to route transmission

lines into substation• Existing utilities/structures• Current land use

G140101

Right-of-WayActivitiesWe strive to build positive,

long-term relationships with landowners and tenants

Right-of-Entry Permit - provide access for:• Environmental assessments• Appraisal work• Survey activities• Cultural and historical resource assessments

Easement Acquisition• Compensation• Terms and conditions• Right-of-Way width

Post Construction• Construction damage compensation• Property restoration

Typical Right-of-Way Width

G140101

Typical examples of the right-of-way required for a 345kV electric transmission line

G140101

EasementCompensation

Determination of land valueLand Market Valuations• Independent appraisers will conduct real estate market study

and analysis• Market study will be focused on the area of the proposed line route• Market study and analysis based on comparable sales and the

highest and best use of property• Each parcel will be viewed and its value determined

Easement CompensationAfter land valuations are completed, and prior to actual negotiations, NPPD will establish easement payment amounts for each parcel based on: • Land valuation• Limited rights obtained by the District• Impacts of structures on farming or land operations• Any other special considerationsBased on past NPPD projects, a payment in the range of 80% of market value of the land area within the boundaries of the right-of-way area is customary.

G140101

EasementCompensationEasement Compensation• 80% of the fee value of the easement area.

Structure Payment• Single Pole — Equal to the fee of 1/2 acre of property per structure• Lattice Tower — Equal to the fee of one (1) acre of property per structurePayment for any special consideration on a case-by-case basis

Contruction DamagesIn addition to the easement payment, the property owner or tenant will be compensated for any damages to crops, fences or other property that may occur during construction or when maintenance is required in the future.

G140101

Stabilization and Restoration

Approach• Landowner input and experience

• Consulting with agencies having Sandhills expertise:- UNL- NRD

- NRCS- NDOR

- NPPD Water Systems Staff- Restoration Contractors

• Minimize construction impact- Effects of routing and siting- Investigate alternative design / engineering- Construction practices / equipment- Livestock control around structures

Tell us your experience• What particular restoration methods /

practices have you found to be effective or not effective?— Mulch— Matting

— Seeding— Compost / Manure

— Products / Techniques— Cattle control near structures

• Develop Restoration Plan based on best practices
