How Do Substations Work?

|

Untangling the various equipment you might see in an electrical substation.

This is a very interesting video. Substations do a lot more then just stepping down the voltage from high-voltage transmission lines. They carefully control the output voltage and frequency, bring together often multiple power lines feeding into the system, they can disconnect and connect lines for servicing and repair. In many ways, substations really are the brains of the local power grid.

The developers of a transmission line that is essential to meeting New York’s clean energy goals and shutting down polluting New York City power plants say they’re still on track to finish construction in 2026 — despite pushing for nearly $3 billion in increased ratepayer subsidies.

The recent ask by the Champlain Hudson Power Express is the latest effort by renewable energy companies to press New York regulators for more public aid for their projects — putting the state in an increasingly difficult bind as it steams toward ambitious climate goals by 2030.

Refrigerants How they work in HVAC systems

In this video we will be learning how refrigerants work in HVAC systems such as refrigerators, air and water cooled chillers as well as split a/c units. The refrigerant removes heat from the building and transfers it into the ambient outside air to produce air conditioning.

ALBANY ?— Electricity prices could rise 64 percent in order to cover inflation and the higher-than-anticipated costs that are becoming apparent in New York’s shift to renewable energy, according to a leading state agency.

“The impact of implementing ACE (Alliance for Clean Energy) NY’s requested relief … would be an increase in weighted average strike (base) prices of 64 percent,” reads part of the comments from the New York State Energy Research and Development Agency, which sets contracts for electricity sales by solar and wind developers.?

What that means for the consumer isn't clear as yet.??
