With computerized outage management systems integrated with customer information systems, utilities reduce the time it takes to repair damage after storms.
Knoxville Utilities Board uses an outage management system that integrates with its geographic information system, giving control room personnel one dispatch view and tool. Modern OM systems can be integrated with other utility software, providing far more detailed information, predictions and analysis in determining the causes of outages. When Doug Nass came to Clallam Public Utility District in Washington state in November 2006 and became general manager, he was not expecting to face three major storms in the next two and a half months.
Clallam PUD, which is both a distribution and a transmission utility, serves a territory that covers 2,000 square miles from the Pacific Ocean on the west nearly to Puget Sound on the east and from the Straits of San Juan De Fuca on the north to the Olympic National Park on the south. During those first storms, "We had a map on the wall, and people calling in, and we used pins and Post-It Notes to show outages," Nass said.
Clallam PUD installed the ESRI GIS and the Responder OMS by Telvent Miner and Miner in the fall of 2007, and the systems went "live" about six months later. The new suite of tools lets Clallam PUD know when lines are getting overloaded, when trees grow over lines, when a particular device repeatedly causes problems, where there's an outage, what caused it, how many people have lost power, and much more. Purvis estimated that return on investment is easily more than 20 percent at this stage, with the SCADA system still to be integrated, and the transmission side of the electrical system yet to be included.
The Knoxville Utility Board in Tennessee covers 750 square miles across eight counties and serves more than 200,000 customers. As with Clallam PUD, integrating the OMS and the customer integration system was one of the biggest challenges. Fayetteville Public Utilities in Tennessee consolidated its electrical, gas, water and wastewater utility operations into one organization in 2002. In Florida, an OMS was installed for the city of Lake Worth's Utilities in 2004, but due to the limited integration ability of the system Rebecca Mattey decided to replace it almost as soon as she became utilities director in 2008. The Sheridan Group of Hunt Valley, Md., is the authorized exclusive seller of reprints of articles published in Public Power magazine. 06 February 2014, Lagos – November 1, 2013 was historic in Nigeria because it was the day the Federal Government handed over public utilities owned by the defunct Power Holding Company of Nigeria to private investors. With an installed power generation capacity of about 10,000megawatts and an available capacity of 6,668.6MW, only a fluctuating 3,400MW or thereabouts is actually generated daily to serve 40 per cent of the nation’s population said to be connected to the national grid.
As it is today, at least 60 per cent of Nigeria’s over 160 million people lack access to electricity, but for the remaining 40 per cent connected to the national grid, power supply has been very epileptic. Generation statistics obtained from the Transmission Company of Nigeria showed that about 2,993.7MW of electricity is being lost everyday largely due to gas shortage, thus resulting in frequent power outages. To show that the integrity of the country’s power infrastructure may be worse than people think, The PUNCH exclusively reported last week that 48 critical pieces of transmission equipment were out of service across the country due to varying faults, fire incidents and vandalism. But one undeniable fact about the private sector takeover of the PHCN companies was the high expectation of Nigerians, who had thought that power supply would immediately take a leap after the change in ownership. Having woken up to the reality that the private investors have no magic wand to supply more than the country’s power generation capacity, electricity consumers are beginning to count their losses from frequent power outages. Beyond being thrown into darkness, they averred that the socio-economic, health and household losses caused by the erratic power supply are huge. Analysts say there are significant negative consequences of the erratic power supply on the consumers’ income, industrial output and commercial activities in Nigeria both in the short and the long run. To work around the inadequate power supply, Nigerians have resortedto generating electricity themselves using diesel and petrol – powered generators. In view of this, the Global Business Intelligence estimated that Nigerians spent about $455m on generators in 2011 and industry analysts said this figure was most likely doubled in 2012 and 2013.
Bringing this into perspective, a power sector consumer poll recently conducted by NOI Polls Limited, revealed that About 69 per cent of Nigerian adults have experienced increase in the amount they spend on alternative power supply, especially generators, compared to the situation a year ago. NOI Polls said it introduced the Power Sector Polls Project in April 2013 in order to ascertain Nigerians’ perception of the power sector reforms, the hours of power supply received daily, and the expenditure on alternative sources of power.
It said the aim of the polls was to monitor power supply trends in the country and prepare quarterly reports on its findings. About 47 per cent of Nigerian adults interviewed in the polls said electricity supply had gone from bad to worse.
The results of the series of power sector polls also indicated that about eight in every 10 of those interviewed generated their own power through alternative sources to compensate for irregular power supply. The polls also showed that 46 per cent of Nigerians saw a drastic increase in spending on alternative power generation in the past year. He said, “For me, the last three months have been frustrating because I have had to spend so much on running generators. The President, MAN, Chief Kola Jamodu, who gave this indication at the 2013 World Stage National Electricity Conference in Lagos, said public power supply had remained inadequate for smooth operations in the manufacturing sector. As a result, he explained that over N42bn had been committed to powering the manufacturing concerns in the country between January 2012 and August 2013.
Jamodu, who was represented by the Chairman, Standing Committee on Infrastructure, MAN, Mr.
From this calculation, another N10bn would have been spent on fuelling generators by the manufacturers, many of who are already in a dire state and struggling to survive. Jamodu said that the electricity power audit conducted on 2,500 members nationwide put the average peak power demand by manufacturers at 4,850 megawatts, and the peak power supply from the Discos at 1,018MW. He said, “It is sad to note that 40 per cent of our production cost goes into the provision of electricity as against five per cent to 10 per cent in other developed economies.
The cost of providing alternative power by corporate organisations and manufacturers, according to the Chief Executive Officer, MainOne, Ms. Similarly, inadequate power supply is said to pose a serious impediment to efficient Information Communications Technology service provisioning in the country. He had also said that about 45 per cent of the indigenous telecoms licensees, who commenced business when the telecoms industry was liberalised in 1993, had collapsed now due to the harsh economic environment, with inadequate power supply being a major problem.

The quality of telecoms services in the country is still not good and experts had stopped at nothing in blaming non-availability of electricity at the over 22,000 base station locations that are powered by generators nationwide for this. By virtue of their size, Small and Medium Size Enterprises are at the receiving end with regards to power outages. They wondered how artisans running businesses such as welding, steel fabrication, aluminium, hair dressing salon and frozen food businesses would survive without adequate power supply.
Joseph Ibikunle and Emmanuel Adebayo of the Department of Economics, Ajayi Crowther University, Oyo and Bowen University, Iwo, respectively, published a paper entitled, ‘An Econometric Analysis of the Impacts of Power Outage on Consumers in Nigeria’ in the Journal of Business and Organisational Development in June 2012. It will be recalled that the NERC Chairman, Amadi, recently lamented that over $10bn NIPP stations were currently operating sub-optimally with some of them totally out due to gas supply shortage. The National Control Centre, Oshogbo, last week, said the Kainji Hydro Power Plant with an installed capacity of 760MW and an available capacity of 100MW, was shut as a result of multiple faults affecting eight of its units. Also, the Sapele NIPP was as of last week totally out due to gas constraints, loading problems and civil work on its basement.
Specifically, the NCC also said the 500MW Olorunsogo NIPP plant was similarly out due to gas constraints and maintenance routine after a commissioning test. This, coupled with very weak transmission infrastructure that cannot be fixed over night, simply points to the stark reality that power outages may not be reduced in the short term.

This episode was a pleasant surprise, as it managed to juggle two opposing villains better than most episodes are able to handle just one. The Flash proved that it can juggle multiple villains without losing sight of its hero and his circle of allies. This blog collects news relevant to the design of current and future energy systems, with a focus on economics, Europe and the Netherlands. Pictured, clockwise from lower left, are John Phelps, Gene Bailey, Mike Vandergriff and Michelle Reimert. Although outage management systems entered the utility scene at least 20 years ago, many municipal utilities are just now starting to take advantage of them. They let everyone involved in an outage have exactly the same view of what's going on, and they enable tactical and strategic planning in ways that couldn't be imagined previously. System costs are typically straightforward, but there are plenty of hidden expenses in terms of months of work and the difficulty and complexity of all that integration. Nass, who headed the municipal utility in Denison, Iowa, before moving to Washington, was unaccustomed to multiple storms in a single season, (despite the Midwest's notorious tornadoes).
Part of this enormous mapping task was erroneous customer information—the customer information system did not correctly map what had been in the utility's previous AutoCAD-based mapping system.
In 2003, the utility replaced its text-based mainframe-based OMS and customer information system with Intergraph InService. Afterwards, CEO Britt Dye also wanted to consolidate outage information to achieve better customer service. This and other integration will take time, and even when everything is integrated, connections won't all be automatic.
Specifically, 11 distribution companies and four generation plants have since exchanged ownership hands.
These included two hydro and five gas-fired power plants and all of these problems have contributed to the country’s poor power supply situation. I don’t know what is happening,” the Chief Executive Officer, Royale Prestige Properties, Mr.
Emmanuel Okoegwale, lamented that power supply had been very erratic after the private investors took over PHCN and added that this would have a negative impact on the balance sheets of small and medium scale enterprises as well as household finances.
This, they say, generally results in factory closure, health problems, lost of lives and property, among others.
The ministry of power estimated that the total electricity generated through this method accounts for about 6,000MW, more than the total commercial power generated and supplied to the national grid. They argued that acquiring generators, buying petrol and diesel for the generators, and periodical repairs and maintenance accounted for the lion’s share of the losses incurred by Nigerians from inadequate power supply. Sola Animasahun, who runs a cold room in Ikeja, Lagos, complained that she had been spending more on fuelling her generator to ensure that her cold room business does not go under. Tobiloba Olusesi, observed that nothing had changed since the polls were carried out and affirmative that subsequent polls would reveal that more Nigerians have spent more on powering their generators. Reginald Odiah, said a 2012 electricity power audit conducted by the association revealed that over N2bn was being spent to fuel generators monthly.
Titi Omo-Ettu, had said, “What the telecoms sector needs now is a radically improved public power supply.
Florensce Oseni, who works as a manager with a Quick Service Restaurant in Lagos, said spending so much on generators would push the common man deeper into poverty. Imagine spending about N10,000 to buy petrol in January because I was trying to prevent food items from spoiling,” she said. Monalisa Azu, a businesswoman in Lagos, said, “Our food stuffs get spoilt due to poor power supply and this is not economically good for us.
Its impact varies from the experience of dark nights to a lot of damage being caused to household equipment. Also, some richer households buy generators which they operate when there is a power outage. Despite its 507.6MW installed capacity, the plant can only account for 250MW available capacity.

Its GT1 unit was shut following a water injection test, while the GT2 unit was shut after a 72-hour performance test. I was honestly surprised the episode didn’t end on a darker note, with Barry’s inability to stop the hostage crisis resulting in a death (or deaths) and Iris’ adoration of the hero cooling. The views expressed here are my own and not those of CWI Amsterdam (the research institute I am employed at). That's smart, since the newest, latest tools have much greater capabilities than those first systems.
Neither was John Purvis, who came from Memphis in June 2007 to be a district manager with the utility.
Among other reasons for its selection, InService worked with KUB's existing GIS, which has 20 years of mapping information in it. As mothers, it is not cost effective for us because we plan our housekeeping budget and we go to the market to buy food stuffs in bulk, which is cheaper.
Many households have their fridge, television sets, video sets and a host of household equipment damaged due to frequent power outages. This is an additional burden to such households; apart from the cost of the generator, they buy diesel or petrol to operate it. It seems like every week the show’s one underwhelming element is its handling of the villains. Instead, we got a more lighthearted resolution and a reminder than Iris can take care of herself in a sticky situation. Barry's character arc was bit cliched, but on the whole this was another satisfying installment for the series. I come across lots of links because I developed a general interest in this important societal topic during my PhD and thus come across lots of news stories. Nevertheless, benefits seem to far outweigh the difficulties, as this snapshot of the experience of four public power utilities shows.
We publish the data once a month to the OMS." KUB plans to adopt ESRI's GIS, which has rules-based maps and will let KUB publish the maps once a week to the OMS. Sam Amadi, have both attributed this to shortage of gas, faults and maintenance works on power plants.
Omoshalewa Johnson, foresee a tough time for SMEs with the current epileptic power situation. But because of the lack of electricity supply, you have to be going to the market almost every two to three days to buy your perishables.
Also, what the household would have purchased in bulk (perishable goods) and kept in refrigerators is bought in bits.
Sometimes I will give only the link, but if time allows, I'll summarise shortly what I think the most important or interesting bits are. From October to January, we get high winds, snowstorms and wet ground, which means trees falling on lines. However, if power supply challenges are resolved, doing business will be a lot easier for all of us. Successfully used to investigate root causes of PJM voltage stability condition in July 1999 and established history in nuclear and defense industries. So the idea of an episode that juggled two completely separate and independent villains wasn’t necessarily enticing. Nonetheless, this is probably the gold standard, against we will measure ourselves in the future, when we have less money to keep the infrastructure at this level. When the system can identify where the calls are, then an operator can likely identify the location of the problem.
The camera cut away just as the two struggled over the gun, and we never saw exactly what happened.
Not to speak of technological developments like renewables, which can further decrease delivery quality . Both villains received an adequate amount of attention even as the focus remained on Barry Allen’s latest personal crisis.
I guess we’re meant to assume from Tockman’s limp that she shot him in the leg or something? Finally, I imagine a lot of DC fans geeked out when Wells rattled off a list of names of those who died in the particle accelerator explosion. Electric powers aside, the version of the character seen here might as well have been an original creation. It seems we can look forward to the eventual debuts of characters like Elongated Man and Fire in addition to Firestorm. The writers basically cast Blackout as this franchise’s answer to Parasite from the Superman comics. He’s all about draining massive amounts of energy for his own sustenance, and the Flash made for a particularly tasty morsel. What mattered is that Blackout was given a sympathetic back-story so that he didn’t become just another metahuman thug. The brief glimpse of Farooq and his friends pre-particle accelerator explosion gave context to his loss and his hatred of Dr. Between that loss and the obvious psychological toll his powers were taking, it was easy to understand why the character was on the warpath. Michael Revantar delivered a solid performance despite not having a lot of variety to work with. Instead, this seemed to be more a case of the writers making use of a good character at a time when his presence made sense.
But with our hero suffering a temporary power loss, suddenly Tockman had his window of opportunity.
