Marcy to New Scotland Upgrade Project



Meet LS Power

Power generation and transmission company formed in 1990

LS Power Project Experience Map

LS Power Grid New York will lead the development, engineering, and construction of this new project with its partner, New York Power Authority (NYPA).



How Does the Grid Work?

• High voltage transmission lines – like the project – efficiently move large amounts of energy around New York State

• High voltage substations act as transmission endpoints and allow energy to step down onto the distribution network

• Electrical energy is produced at generating stations

– Hydropower – Renewables like wind and solar – Natural gas-fired turbines – Other generation types

GENERATION TRANSMISSION DISTRIBUTION

• Distribution lines move energy more locally

• Typically, one final step down in voltage is required near your home or business for end use


Why is This Project Needed?• Congestion on New York’s grid

limits new renewable resources in upstate areas and creates higher energy prices for consumers

• The result of New York State’s 2012 Energy Highway Blueprint, which has evolved into the Clean Energy Highway

• The New York grid operator (NYISO) and the Public Service Commission identified electric transmission system issues requiring solutions in 2016

• NYISO selected LS Power and New York Power Authority’s joint proposal in April 2019, from among seven solutions submitted by various qualified project sponsors, as the most efficient and cost-effective project

• Complements other transmission projects underway across New York State

• The project will use existing electric transmission corridors

• Removing more than 1,250 aging transmission structures from the existing corridors and replacing with only about 600 new structures

• Constructing a new substation in Princetown and expanding an existing substation in Rotterdam



Project Benefits for the Mohawk Valley and Capital Region

• Major investment in the electrical grid will:

– Create hundreds of construction jobs

– Generate significant local annual tax revenues

– Support renewable energy resources, reducing carbon dioxide and other emissions

– Improve electric grid reliability and resiliency

– Reduce transmission system congestion, allowing the lowest cost, most efficient, and environmentally-friendly generation to better meet electrical demand

– Help meet New York State’s for-ward-looking clean energy goals

Guiding Principles: Our Commitment to Environmental Protection

Our Commitment to the Community

1. Identify sensitive resources through research and field surveys

– Wetlands, historical architecture, archaeological sites, threatened or endangered species, agricultural land, invasive species, and others

2. Work with our engineers to strive to avoid these resources altogether

3. Employ innovative technologies and techniques to minimize impacts

4. Coordinate with regulatory agencies to determine appropriate conservation measures – like funding the creation of new wetland areas

1. Listen to ideas from neighbors2. Minimize project effects on and off the

electric transmission corridors3. Reduce the number of structures while

limiting heights and viewshed4. Meet state guidelines for noise and

electromagnetic fields5. Provide safe and reliable electric

transmission service6. Ensure conditions are as good or better at

the end of construction



Technology and Best Practices to Be a Good Neighbor



• Noise – Innovative gas insulated substations to be located within

buildings, meaning no noticeable off-site noise during normal operations

– Careful attention to the layout of new transformers at the Rotterdam substation to minimize noise and meet New York State guidelines at neighboring properties

nLocating far from property boundaries and homes nTaking advantage of barriers like firewalls and natural

site terrain nRetiring three older transformers at the current substation – Modern transmission design minimizes corona effects,

which create the faint buzz during certain conditions

• EMFs – Electric and magnetic fields (EMFs) are generated by any

electrical device – New York State sets

guideline limits for EMFs for transmission lines at the edge of utility property nElectric fields: 1.6 kV/m nMagnetic fields: 200 mG

– We will minimize EMF levels at the edge of the right of way through careful design – even reducing values on some segments below existing levels

A few everyday appliances:

Transmission Line Construction



1. Right of way and staging yard preparation and installation of stormwater controls

2. Construct access roads

3. Remove existing lines

4. Construct new lines – Install foundations – Erect structures – String conductors

5. Conduct offline testing

6. Energize for operation as part of the New York State grid

7. Restore construction areas

Substation Construction



1. Site preparation and installation of stormwater controls

2. Substation construction – Site grading – Install grounding and foundations – Construct gas insulated substation

building – Install equipment, such as breakers,

switches, transformers, and controls – Erect transmission line terminations

3. Conduct offline testing

4. Energize for operation as part of the New York State grid

5. Restore construction areas

Operations and Maintenance



• Operations – As with all transmission grid facilities in New

York State, NYISO will operate the project and provide instructions on a minute-by-minute basis to generators, transmission owners, and others to keep the lights on, based on real-time electrical demand, outages, and other conditions

– NYPA is planned to control the project, meaning NYPA will respond to NYISO’s instructions, for example, opening and closing breakers or switchesnRemotely from NYPA’s existing local control

centernOn-site at the new Princetown or Rotterdam

substations – Substations will include state-of-the-art security

measures to allow remote monitoring

• Transmission Line Maintenance – Typical routine maintenance similar to existing

linesnVegetation management on a four-year cycle,

including annual phases for inspection, full right-of-way treatment, and re-inspection/spot management

nPeriodic line inspections one to two times each year by helicopter or drone

nRepairs performed as needed

• Substation maintenance – Substations are not planned to be permanently staffed – Routine inspections expected a couple of times each month – Repairs performed as needed
