The Importance of Electrical Construction Permit Inspections

3-Phase-Image

THE PERMIT AND INSPECTION PROCESS IS ESSENTIAL TO ENSURE THAT CODES, REGULATIONS, AND SAFETY ARE ENFORCED TO HELP PREVENT FAULTY OR POOR INSTALLATIONS THAT COULD JEOPARDIZE HUMAN LIFE. IN MOST CASES, ENGINEERING BLUEPRINT DRAWINGS ARE REQUIRED TO BE SUBMITTED ALONG WITH THE PERMIT REQUEST WHICH MUST BE SEALED BY A REGISTERED PROFESSIONAL ENGINEER (PE). OTHER PERMITS WITH SEALED DRAWING PLANS ARE REQUIRED FOR EACH DISCIPLINE, SUCH AS, ARCHITECTURAL, CIVIL, ELECTRICAL, FIRE PROTECTION, MECHANICAL, PLUMBING, STRUCTURAL, ETC.

Direct Satellite-to-Mobile Services Emerge

Cellphone-Satellite-Communications

By EETimes / Design Lines: “In just over 12 months, direct satellite-to-mobile communications have morphed from being a Sci-Fi pipe dream to a real-world prospect.

Apple and T-Mobile are separately rolling out schemes with Globalstar and SpaceX, respectively, to enable customers to connect to signals delivered from space. Amazon is preparing for multiple launches of its low earth orbit (LEO) Project Kuiper satellite constellation.

Startups such as AST SpaceMobile and Lynx Global have signed satellite-to-cellphone deals with multiple mobile network operators (MNOs) across the world—even before the official launch of spacecraft that will enable these services.

Google, meanwhile, is working on its own software project that will speed up communications between terrestrial networks and satellites in orbit. In September, Google spun out a startup called Aalyria to work on network orchestration software that connects systems on the ground with those deployed on planes and in space.”

Canada OPG and Czech Republic Partner to Advance Small Modular Reactors

Nuclear-SMRs

By PowerMag: “Ontario Power Generation (OPG) and Czech Republic-based ČEZ are collaborating to advance deployment of nuclear technology, including small modular reactors (SMRs). The companies said they signed a memorandum of understanding (MOU) on Oct. 11, with an aim to “reduce financial, technical and schedule risk to both parties on their respective future projects.”

“OPG is Ontario’s largest electricity generator. The company has 75 generating stations in the province with a combined capacity of more than 18 GW. In addition to 66 hydroelectric facilities, its fleet includes two nuclear stations—the 3.5-GW Darlington facility and the 3.1-GW Pickering station (Figure 1). OPG says nuclear power provides about 60% of Ontario’s power today.”

Xcel Energy Strengthens the Grid with Advanced SVCs

Static-VAR-Compensators

T&D World – Xcel Energy uses flexible static VAR compensator topology to adapt to changing network conditions in New Mexico for more stability and voltage control.

In 2010, Xcel Energy Inc. was tasked by Southwest Power Pool Inc. (SPP) to build out the transmission system in southeast New Mexico, U.S., because the oil and gas industry in the area had a growing need for electricity. Oil producers were asking to convert from expensive diesel to more affordable electricity for their pumps. The request from SPP consisted of a transmission system expansion of new 115-kV and 345-kV projects in the region. Spending had to be prioritized between 2010 and 2021 because of the sheer scale of the plan needed to successfully implement the request.

Xcel Energy addressed the plan by implementing projects classified as high priority. This plan resulted in initiating 44 new transmission projects, an investment of US$557 million. In 2016, two static VAR compensators (SVCs) — the China Draw and Roadrunner — were built in southeast New Mexico to support SPP’s request.

To build or not to build: TVA asks public to weigh in on construction of large solar farm

TVA-PV-Solar-Farm

RenewableEnergyWorld – The Tennessee Valley Authority (TVA) is asking for public input on the draft Environmental Impact Statement for the North Alabama Utility-Scale Solar Project in Lawrence County.

In January 2019, TVA announced that it holds a two-year purchase option on 3,000 acres in Lawrence County to study the feasibility of building a large solar farm in order to continue reducing its carbon footprint.  

The purpose of this EIS is to address the potential environmental effects associated with constructing, operating, maintaining, and decommissioning the solar facility.

The draft EIS includes two alternatives: a No Action Alternative and an Action Alternative. Under the No Action Alternative, TVA would not execute the purchase under the Purchase Option Agreement, and TVA would not develop a solar facility at this location. Under the Action Alternative, TVA would execute the purchase under the Purchase Option Agreement for the Lawrence County, Alabama, property.
