I was pretty bored today lol
Turneresque light yesterday evening. Shame about the powergrid wires... but not much to do about them.. :~)
This is largest wind farm in Tamil Nadu, along the Pollachi-Pazhani Highway. Electricity generated from this farm determines the power position of Tamil Nadu as it contribute a major share to the total energy requirement.
The place is Anthiyur, near Udumalpet, Tamil Nadu.
innumerable electric power and telephone lines are tangled together on a single utility pole near Durbar Square, Kathmandu, Nepal.

Grey bar represents the theoretical maximum capacity at the time.
2008 saw the total wind power generation capacity in Ontario double (again -- it also doubled in 2007.) On the best day, we can now exceed 800 MW. On the worst day, the entire province's wind turbines put out, basically, 0 MW.
Can the rest of the system adapt to this variability?
So far, of course it can. Note that the power generators already need to deal with demand variability that can go from 13 GW to 25 GW daily. You can see some of this output modulation occurring at a coal plant:

And it turns out natural gas power plants can and do modulate up and down much faster than coal plants, so the replacement of coal with natural gas means more stability for the grid, as well as cleaner emissions and somewhat less CO2 per kilowatt*hour. In Ontario, this replacement is almost complete.
Note that Ontario gained additional ability to handle load and wind variability on 11 Sep 2013 when OPA introduced curtailment, a policy that lets the system operator turn off production at wind farms when demand is low and total production is higher than needed.

Pump jacks at dawn in Inglewood Oil Field in Ladera Heights, California.
This 1,000 acre urban oil field happens to be the largest contiguous oil-producing site in the Los Angeles area. It's interesting to think that these oil fields are in the midst of the city and only a few miles away from the ocean. You can also see the Hollywood Hills in the distance.
I'd bumped into Lee from our local utility company, LG&E (aka PPL), today and Lee was kind enough to explain what they were doing and why this project would take so long. He explained the various obstacles and challenges with this particular job. As with many other excavations in Louisville, there was great difficulty locating the existing utilities already in place. He said today they were waiting for the Dew Point - en.wikipedia.org/wiki/Hydrocarbon_dew_point
I'd only asked because from the untrained eye it looked like a bunch of guys just standing around all day.
Lee said this project could take another three weeks to wrap up as they (and their subcontractor, Miller Construction) complete all of these jobs exactly according to their specifications and this is a challenging corner. It was nice being out in the field again watching this work being done, having been the sole municipal inspector assigned to Transco's 24" gas main pipeline up north eons ago. Work styles & workmanship have certainly changed since then.
I did ask Lee about the numerous utility poles in this area that are split and leaning like the Tower of Pizza. He explained he was solely with the gas end of LG&E and not electric.
He is a very knowledgeable gentleman with an insanely firm handshake. Although LG&E is not one of my most favorite companies, Lee did give me some confidence that this job would be done correctly. He is required to stay with the subcontractor for the entire duration of the job, he said.
We are very grateful our utility grid challenges are finally being addressed as we have had many gas leaks in this area.

The Hyderabad Metro is a rapid transit system, serving the city of Hyderabad, Telangana, India. It is in Secant Operational model. It is being implemented entirely on public-private partnership (PPP) basis, with the state government holding a minority equity stake. A 30 km stretch from Miyapur to Nagole, having 24 stations was inaugurated on 28 November 2017 by Prime Minister Narendra Modi. No other rapid transit metro service in India opened for public operations on such a long stretch of 30 km. As of October 2018, it is the second longest operational metro network in India after the Delhi Metro, after a 16 km stretch between Ameerpet-LB Nagar Metro route was opened on 24 September 2018. It is estimated to cost ₹18,800 crore (US$2.6 billion). As of October 2018, about 200,000 people use the Metro per day. Trains are now crowded during the morning and evening hours, when employees travel to and from work. A ladies only coach was introduced on all the trains from 7 May 2018.
HISTORY
To respond the rising public transport needs and mitigate escalating vehicular traffic in the twin-cities of Hyderabad and Secunderabad, the State Government and the South Central Railway jointly launched the Multi Modal Transport System (MMTS) in [August] 2003. The increase in population of Hyderabad made MMTS alone insufficient for public transport, which led to Union Ministry of Urban Development giving the nod for the Hyderabad Metro Rail Project and directed the DMRC to conduct a survey on the project.[ this project was seen necessary in view that the population of Hyderabad was forecasted to reach 13.6 million by the year 2021. According to the initial plan, the metro was to be connected with the already existing MMTS to provide commuters with alternate modes of transport. Simultaneously, the proposals for taking up the construction of MMTS Phase-II were also taken forward.
On March 26, 2018, Telangana Govt announced that it would set up a SPV "Hyderabad Airport Metro Limited (HAML)", jointly promoted by HMRL and HMDA, to extend the Blue line from Raidurg to Rajiv Gandhi International Airport, Shamshabad.
INITIAL BIDDING
The bidding process was completed by July 2008 and awarded to Maytas which failed to achieve financial closure for the project as per schedule By March 2009. In July 2009, the State Government cancelled the contract and called for fresh bids for the project.
RE-BIDDING
In the July-2010 rebidding process, Larsen & Toubro (L&T) emerged as the lowest bidder for the ₹121.32 billion (US$1.7 billion) project. L&T came forward to take up the work for about ₹14.58 billion (US$200 million) as viability gap funding as against the sanctioned ₹48.53 billion (US$680 million).
MASCOT
The mascot of Hyderabad Metro Rail is Niz. It was derived from the word Nizam, who ruled the princely state of Hyderabad.
AWARDS AND NOMINATIONS
HMR project was showcased as one of the top 100 strategic global infrastructure projects at the Global Infrastructure Leadership Forum held in New York during February–March 2013.
L&T Metro Rail Hyderabad Limited (LTMRHL) has been conferred the SAP ACE Award 2015 in the 'Strategic HR and Talent Management category.
In 2018, Rasoolpura, Paradise and Prakash Nagar metro stations were awarded Indian Green Building Council’s (IGBC) Green MRTS Platinum Award.
CONSTRUCTION HISTORY
Groundbreaking (Bhoomi Puja) for the project was conducted on 26 April 2012 the concessionaire started the pillar erection on the same day for Stage-I and on 6 June 2012 for Stage-II. The work for Corridor 2 has been delayed due to traders in Koti and Sultan Bazar demanding realignment of the route to safeguard traders and old age heritage markets. If the recent bill proposed in Parliament which allows construction within a 100 metre radius of heritage structures and sites of historical or archaeological importance is passed, Metro might receive a chance as it helps to connect the Old city with IT corridor.
The construction of the entire 71.16 km has been split into 6 stages with the first stage originally scheduled to be completed by March 2015.
In November 2013, L&T Hyderabad Metro started laying of rails on the metro viaduct between Nagole and Mettuguda, a stretch of 8 km.
The first highly sophisticated train of the Hyderabad Metro Rail (HMR) came from Korea during the third week of May 2014. Stringent trial runs commenced from June 2014 till February 2015. The trial runs started on the Miyapur to Sanjeeva Reddy Nagar stretch in October 2015.
CMRS inspection for Stage-II (Miyapur and S.R.Nagar Section) was done on 9, 10 August 2016. Three interchanges are planned at Mahatma Gandhi Bus Terminus, Parade Grounds and Ameerpet.
The steel bridge of the HMR was successfully placed over the Oliphant bridge in August 2017.
In November 2017, Commissioner of Railway Safety (CMRS) granted safety approval for 12 km stretch from Miyapur to SR Nagar, 10 km stretch from SR Nagar to Mettuguda and 8 km stretch from Nagole to Mettuguda.
Ameerpet-LB Nagar Metro stretch is open for commercial operations from 24 September 2018.
CONSTRUCTION PHASES
The construction work was undertaken in two phases. There are six stages of completion in Phase I
PHASE I
The Phase I of the project includes 3 lines covering a distance of around 72 km. The metro rail stretches between Nagole and Secunderabad 11 km originally scheduled to be operational by December 2015, is now partially operational since 29 November 2017. The entire 72 km 57-station first phase is due to be completed by December 2019 with Hitec City - Raidurg line and MGBS - Falaknuma line is scheduled to be completed by December 2019.
Line 1 - Red Line - Miyapur – L B Nagar - 29.2 km
Line 2 - Green Line - JBS - Falaknuma 15 km
Line 3 - Blue Line - Nagole – Raidurg - 28 km
PHASE II
The Government is planning second phase of metro rail extending further. The construction of Phase II will be taken up solely by the state government, instead of public private partnership (PPP) mode in Phase I. Delhi Metro Rail Corporation (DMRC) was entrusted to give a detailed project report (DPR) for Phase II. Metro Rail Phase II expansion plan is for about 60 km, which includes providing link to Shamshabad RGI Airport.
LINES
Since the first version of the plans, the three corridors mostly remained the same, but minor changes were introduced. These include the lack of stop at Lalaguda, or a stop at Lakdikapul instead of Secretariat. Also, the lines have been marked with several different combination of color. Ameerpet- LB Nagar metro stretch opened on 24 September 2018. HiTec City to Raidurg, 1.5-kilometre stretch on Corridor Three - Nagole to Raidurg, is scheduled to be completed in November 2019, as it involves construction of 49 pillars and the Raidurg terminal station. Efforts are being made to complete the 8.5-km stretch from Ameerpet to HiTec City by December 2018.
RECEPTION
The Metro has opened to overwhelming response, with over 200,000 people using it on Day 1. On the first Sunday of operations, the Metro was used by 240,000 people.. As of September 2018, the daily ridership was about 2,00,000.
Trains are initially being operated at a frequency of 3.5 minutes in very peak hours and every 6.5 minutes in peak hours (between Miyapur-Ameerpet) and 6.5 minutes in peak hours (between Ameerpet-Nagole),, though maximum achievable frequency is every 90 seconds. Similarly, three-car trains are being used currently, though it is planned to use six-car trains in the future.
In December 2017, Hyderabad Metro Rail launched its mobile app, TSavaari. Hyderabad Metro timings are available on T-Savari app. Ola Cabs and Uber tied up its services with app.
COST
The initial official estimated cost of the 72 km long Metro project stood at ₹14,132 crore (US$2.0 billion). The Central Government decided to bear 10% of it, while L&T was to bear the remaining 90% of the cost. The construction work which was supposed to commence on 3 March 2011 commenced in 2012. In March 2012, the cost of the project was revised upwards to ₹15,957 crore (US$2.2 billion). This has been further revised upwards to ₹18,800 crore (US$2.6 billion) (as of November 2017).
INFRASTRUCTURE
The 71.3 km standard-gauge network will feature ballastless track throughout and will be electrified at 25kV ac 50 Hz. An operations control centre and depot are constructed at Uppal. At some places, a flyover, underpass and metro has been constructed at the same place, as part of Strategic road development plan (SRDP).
CBTC TECHNOLOGY
At the end of 2012, L&T Metro Rail awarded Thales a Rs 7.4bn ($US 134m) contract to provide CBTC and integrated telecommunications and supervision systems on all three lines. Thales will supply its SelTrac CBTC technology, and trains will initially run in automatic train operation mode with minimum headways of 90 seconds, although the system will support eventual migration to unattended train operation (UTO).
ROLLING STOCK
On 12 September 2012, Larsen and Toubro Metro Rail Hyderabad Ltd (LTMRHL) announced that it has awarded tender for supply of rolling stock to Hyundai Rotem. The ₹18 billion (US$250 million) tender is for 57 trains consisting of 171 cars which will be delivered in phases at least 9 months before the commencement of each stage. On 2 October 2013, LTMRHL unveiled its train car for Hyderabad Metro. A model coach which is half the size of the actual coach, was on public display at Necklace Road on the banks of Hussain Sagar in the heart of Hyderabad. The trains will be 3.2m wide and 4m high. There will be 4 doors on each side of each coach.
On 10 April 2014, the first metro train for HMR rolled out of Hyundai Rotem factory at Changwon in South Korea and reached Hyderabad in May 2014. On 31 December 2014, Hyderabad Metro Rail successfully conducted a training run in Automatic Train Operation (ATO) mode for the first time between Nagole and Mettuguda.
TICKETING
The L&T Hyderabad project will have an automated ticketing system with features such as contactless smart card based ticketing, slim automatic gates, payment by cash and credit/debit card, passenger operated ticket vending machine and provision of common ticketing system. It will also have a provision of NFC-based technology to enable usage of mobile phones as fare media and high performance machine to avoid long queues. Samsung Data Systems India, a subsidiary of South Korean firm Samsung, has been awarded the automatic fare collection system package for the L&T metro rail project. The package involves design, manufacture, supply, installation, testing and commissioning of the system.
Official ticket prices were announced on 25 November 2017. The base fare is ₹10 for up to 2 km and going to slap 10 with ₹60 for more than 26 km.
STATIONS
Hyderabad metro will have 64 stations in phase I. They will be provided with amenities such as escalators and elevators to reach the stations, announcement boards, electronic display systems among others for passengers. Commercial will also be provided on stations. Hyderabad metro stations will also have service roads underneath them to provide last mile connectivity by allowing other public transportation systems use it for dropping/picking passengers right in front of the stations and ensure uninterrupted traffic. Currently the service lane works are currently on at Nagole and Uppal stations. The signboards of Hyderabad Metro are displayed in Telugu, English, Hindi and Urdu at metro stations.
Otis Elevator Company of United States won the contract to supply and maintain 670 elevators.
In May 2018, L&T Metro Rail announced that it had signed a contract with Powergrid Corporation of India to install electric vehicle charging facilities at all metro stations beginning with Miyapur and Dr. B R Ambedkar Balanagar stations. L&THMRL has setup free wifi access units for commuters at Miyapur, Ameerpet and Nagole metro stations, in association with ACT Fibernet, as part of a pilot project.
