Energy Storage: Can It Replace Transmission? (KEMA)
Aug 31st
Aug 31, 2010
By Rick Fioravanti
Grid-scale storage offers potential benefits to transmission and distribution systems of utilities in regulated and market environments. These benefits derive from cost reductions due to the time and location shifting of energy for congestion relief, reliability via enhanced stability and outage response, and incremental voltage support—once the storage device and its power electronics are in place.

Jul 19th
Jul 16, 2010 4:19 PM Midwest ISO
After more than 19 months of collaborative work with its stakeholders, the Midwest ISO filed its proposed cost allocation methodology for new transmission projects. Multi Value Projects (MVPs), transmission projects that have a regional impact and are part of a regional plan, will now have a 100% regional allocation of costs, pending the Federal Energy Regulatory Commission’s approval.
“This system will fairly and equitably share the cost of projects that benefit the entire region and enable the Midwest ISO and its members to continue delivering low cost and reliable energy to the region,” said John Bear, president More >

Jul 2nd
Jun 30, 2010
Neglected on the back burner for years, high-voltage electricity transmission systems throughout the world are expected to see investments of more than $600 billion globally from 2010 to 2020, according to an analysis by market consulting and research firm Pike Research. The report notes a number of drivers at work here: population and economic growth, policy initiatives and a rejuvenated industry focus. The evidence? Thousands of miles of new transmission lines are being built and existing systems are being beefed up to add capacity and more monitoring capabilities.
Quick Take: Serious investment in transmission is critical if we’re going to meet the growing demand and More >

Industry-wide Transmission Efficiency Initiative
Apr 30, 2010
One of the thornier problems facing implementation of the Smart Grid is the grid’s transmission system. But the Electric Power Research Institute (EPRI) has come to the rescue by forming a brain trust of utilities and transmission system operators to compile and analyze data from transmission lines, substations and grid operations to develop ways to cost effectively improve the inadequate existing system. More than 20 organizations and 33 proposed transmission projects will feed data into the collaborative effort. It’s an outgrowth of previous efforts by EPRI and the Federal Energy Regulatory Commission (FERC) and industry stakeholders to More >

Apr 21st
Apr 19, 2010 9:47 PM Southwest Power Pool
Today the Southwest Power Pool, Inc. (SPP) Board of Directors and Regional State Committee, comprising regulatory commissioners from seven states, filed with the Federal Energy Regulatory Commission a new “Highway/Byway” method of sharing costs for electric transmission in the SPP region, which includes all or parts of Arkansas, Kansas, Louisiana, Mississippi, Missouri, Nebraska, New Mexico, Oklahoma, and Texas.
“Most in the electric utility industry agree that new transmission is needed to continue delivering reliable and lower-cost electricity to consumers. The big question has been: Who will pay for that infrastructure?” said SPP President and More >

Mar 19th
Mar 18, 2010
The Federal Energy Regulatory Commission (FERC) has given its initial stamp of approval for the Tres Amigas superstation that would, for the first time, unite the country’s three electric grids, and efficiently bring Smart Grid renewables to market. But the commission — which said it didn’t have enough information to make a decision — declined to drop its authority over the project’s connection with the Electric Reliability Council of Texas (ERCOT), the Texas grid over which FERC has no control. Read more about the FERC decision.
Quick Take: Despite the procedural glitch, this is good news. It’s past time to get busy More >

Mar 19th
Mar 19, 2010
There’s a 33-mile electricity transmission line that spans San Francisco Bay — and it’s under water. There’s another one in New Jersey and more ambitious underwater projects in the works. While laying cable under water presents a unique set of challenges, public opposition to overhead lines and other issues have been severe stumbling blocks for integrating renewable energy sources with the Smart Grid. Read more about underwater transmission projects.
Quick Take: This instance of Smart Grid technology innovation is a good example of “If you can’t go through it, go around it” (or in this case, under it). It’s obvious that thousands More >

Mar 4th
Mar 3, 2010
The Electric Power Research Institute says a superconducting direct current (DC) cable could drop transmission line losses, one of the goblins in moving power from one place to another, by more than 50% — and that it could be available within 10 years using existing technology. Here’s more on the report.
Yes, transmission line loss is a big deal. So are 20 years of underinvestment and the possibility that our power grid could choke on the growing amounts of wind and solar energy coming online. Transmission in the Smart Grid era will need a lot of help coping with these issues, and More >

Restricted Content – Entergy Regulators form Regional State Committee
Dec 30th
Entergy’s Retail Regulators have announced the formation of the Entergy Regional State Committee designed to provide collective retail regulatory agency input on the operations of and upgrades to the Entergy Transmission System as well as operations and functions of the Independent Coordinator of Transmission (ICT) in the Entergy region. The members of the E-RSC are five retail regulators of Entergy operating companies: Arkansas Public Service Commission (APSC); Louisiana Public Service Commission (LPSC); Mississippi Public Service Commission (MPSC); Public Utility Commission of Texas (PUCT); and the city of New Orleans’ City Council (CNO). The formation of the E-RSC follows …

Restricted Content – New Energy Transmission IEEE Standard Now Available
Dec 30th
IEEE has published its latest energy transmission standard: IEEE C57.12.38, “IEEE Standard for Padmounted-Type, Self-Cooled, Single-Phase Distribution Transformers; High Voltage, 34 500 GrdY/19 920 V and Below, Low Voltage, 240/120 V; 167 kVA and Smaller.” This standard covers certain electrical, dimensional, mechanical characteristics and safety requirements of single-phase, 60 Hz, liquid-filled, self-cooled, padmounted, compartmental-type distribution transformers. These transformers are rated 167 kVA and smaller, with the high voltages of 34 500 GrdY/19 920 V and below for operation between one phase and grounded neutral, and low voltage of 240/120 V.
