Electricity transmission and distribution

Again, this is not to say that no one will buy a home pem. There are parts of the country where electricity prices are very high, where there are electricity transmission and distribution constraints, and where there are severe air quality problems that make it difficult to build new generation. This is a small but genuine market, especially for people with large homes. Also, first adopters of technology will no doubt be interested in home fuel cells. My point is merely that the market is far less attractive than is widely perceived, especially for a market entry of pems. 

Locating power sources closer to where electricity is used puts less strain on the electricity transmission and distribution lines. It is increasingly difficult and expensive to site and build new power lines, so if the old lines are nearing capacity, load-centered generation can postpone the need to build new lines and reduce the chance of power outages (see the discussion under Benefits of Load-Centered Generation ). 

Since H2 can be burned in gas turbines, these turbines could provide an early market for additional H2 production— assuming that the H2 is not generated from natural gas. Turbines located at the site of the hydrogen production could generate electricity, which could be transmitted via the usual electrical transmission and distribution (T D) system to residential, commercial, and industrial users. 

Home fuel cell power may be utilized in those parts of the country where electricity prices are very high and in rural areas where there are electricity transmission and distribution problems. 

The production sensitivity and capital cost sensitivity for electrolysis allow the user to alter the source of the electricity. The default electricity option assumes electricity is produced using gas combined cycle technology (GasCC). The user may also directly set a price (User Set option). The electricity costs are calculated at the plant gate and do not include transmission and distribution (T D) costs. T D costs may be added by the user (Electricity Transmission and Distribution box).

Direct Current - A type of electricity transmission and distribution by which electricity flows in one direction through the conductor usually relatively low voltage and high current typically abbreviated as dc. 

Energize(d) - To send eiectricity through a electricity transmission and distribution network a conductor or power line that is carrying current. 

Grid - A commmon term refering to an electricity transmission and distribution system. 

Line Loss (or Drop) - Electrical energy lost due to inherent inefficiencies in an electrical transmission and distribution system under specific conditions. 

Stand-Aione Generator - A power source/generator that operates independently of or is not connected to an electric transmission and distribution network used to meet a load(s) physically close to the generator. 

Wheeling - The process of transmitting electricity over one or more separately owned electric transmission and distribution systems. (See Wholesale and Retail Wheeling.)... 

Note Fall protection requirements for scaffolds (including aerial lifts), cranes and derricks, steel erection, tunneling operations, electric transmission and distribution fines and equipment work, and stairways and ladders are found in otfier subparts in the construction regulations. 

As used in Subpart V, the term construction includes the erection of new electric transmission and distribution lines and equipment, and the alteration, conversion, and improvement of existing electric transmission and distribution lines and equipment. Notwithstanding all of the above. Subpart V does not apply to electrical safety-related work practices for unqualified employees. 

It is essential to have organizational entities which are able to perform electrical capacity and electrical transmission and distribution system planning, consistent with various national requirements and objectives. The functions of these organizations include electrical system expansion planning, and manpower and industrial capability assessments. 

Unless an employer is using the maximum transient overvoltages specified in Table V-8 for voltages over 72.5 kilovolts, the employer must use persons knowledgeable in the techniques discussed in this appendix, and competent in the field of electric transmission and distribution system design, to determine the maximum transient overvoltage. 

Power lines means electric transmission and distribution lines.
