In an effort to improve reliability, Pepco, the utility serving Maryland and Washington, DC, has two construction projects in progress that will help maintain the supply of electricity for its customers.
Extending broadband services to more customers is a priority for telecommunications and cable television companies who are locked in a fierce battle to consolidate and expand their shares of the high-speed Internet market and, with it, other bundled services; fiber optic technology is a key element
As 2005 came to a close, many economists blamed a cloudy future on a femme fatale named Katrina. Anthropomorphism, giving human characteristics to something inanimate, is a tricky device, usually frowned upon in writing.
Between a troubled public utility power grid, unprecedented demand for power by a growing population and the need to protect an increasingly digitally dependent economy, everyone from major manufacturing facilities to homeowners are recognizing the need and value of the protection and capabilities
Horizontal directional drilling (HDD) is an innovative “trenchless” construction procedure. It has been in use for a dozen years to make trenchless installations of cable, conduit and duct in areas where surface improvements or crowded utility easements make excavation impractical or impossible.
Unusual circumstances affected the planning for the new Omaha JATC facility. The International Brotherhood of Electrical Workers (IBEW) Local 22 and National Electrical Contractors Association (NECA) Nebraska chapter shared a building and were looking for more space together.
A utility-interactive photovoltaic (PV) system is defined in Section 690.2 of the National Electrical Code (NEC) (NFPA 70-2005) as a “photovoltaic system that operates in parallel with and may deliver power to an electrical production and distribution network.” NEC Article 690 covers Solar Photovol
Photovoltaic (PV) modules convert sunlight directly into electrical energy. Integrating PV into a building will impact its operation. Not only will the PV system produce electric energy to serve building loads but it can also reduce the building's electric demand and air-conditioning heat load.
The installation of photovoltaic (PV) equipment is governed by a number of industry codes and standards. Electrical contractors need to be aware of the codes and standards to ensure a safe and functional PV installation.
Photovoltaics (PV) are semiconductors that convert sunlight directly to direct-current (DC) electric power. Photovoltaic technology has been used for years in specific applications where conventional utility service is not readily available or practical.
The electrical contractor's job on a typical construction project goes beyond the scope of traditional electrical installations. It's a two-part responsibility that includes the construction or renovation of electrical systems for the structure.
Distributed generation (DG) refers to the practice of locating small-scale electric generating units at or near the load served. With distributed generation, individual buildings or complexes can have a local electric power supply that provides some or all of the facility's electric energy needs.
Earlier this year, routine activities came to an abrupt halt at San Bernardino Valley (Calif.) College when a construction crew excavating with a backhoe struck a power cable, causing a small explosion that knocked out a campus transformer.
You could not find two adjacent states taking more opposite approaches to electric markets than Maryland and Virginia. But they still have one thing in common that could be good for electrical contractors. Governors of both states have issued orders for conservation upgrades worth millions.
Concerns about the efficiency and reliability of electricity are prompting new responses by federal and state government agencies, utilities, associations and product manufacturers. They could provide new business for electrical contractors if you can position your company for these opportunities.
New utility business regulations could affect you Is electric transmission a natural monopoly or not? Does the Federal Energy Regulatory Commission (FERC) have authority over states and utilities to order restructuring and regulation of transmission systems?
Submeters are installed after the main utility meter to gain additional information regarding energy usage inside a facility, according to Don Millstein, president of Langhorne, Pa.-based E-Mon Corp. Estimates for the submetering market are primarily based on existing facilities, although U.S.
