Apart from the alliance arithmetic that worked in favour of the AIADMK that won with an absolute majority, the DMK also suffered the wrath of voters for the long hours of power cuts.

Analysts later pointed out that the major reason for the DMK's defeat was load shedding. Officials estimated that the State was short of over 4,000 MW.

Five years on, the fruits of starting several power initiatives have finally borne fruit. Now, Tangedco officials state their belief that the power position is comfortable. Chief Minister Jayalalithaa knows this well and has frequently taken credit for the turnaround in power situation.

In the past five years, the State has added over 3,000 MW in thermal power generation alone.

To be factual about this, technically, all the projects that have helped improve the power situation now, were launched during the previous DMK regime in 2007 to 2009 .

The AIADMK can certainly claim that the MoUs for some of the plants like in Vallur were signed in 2002 itself but the fact is that the units were completed only in 2012 and later. A decade had passed in between. And, meanwhile, Tamil Nadu had lost out on its power surplus status, and probably on thousands of crores in investments. While the AIADMK and the DMK blame each other, as alternate rulers of the State, it is fair that both share the blame.

In fact, the genesis of the crisis dates back to the 1990s. During 1991-96, Jayalalithaa, in her first term, signed agreements with a number of private producers. Only a few took off. The DMK government that succeeded it cancelled the agreement for the Jayamkondam project with a consortium and changed the bidding process but nothing came out of it.

Then the DMK government invited bids for 20 fuel power projects following the Central policy on using liquid fuel for power plants to provide immediate relief to power shortage. Only a handful joined and the power purchase agreement from these independent power producers at “high cost” was embroiled in controversy till last year as both the AIADMK and the DMK continued with the purchase citing the 15-year contract and power shortage scenario.

The present AIADMK government, which boasts of the turnaround over the past five years, has struggled hard to launch thermal power projects though, mainly due to the legal battles it had to wage in the Madras High Court. In 2014, the first supercritical thermal power plant at Ennore was launched which could take two more years to be commissioned. In between the legal battle forced it to change the bidding process. Now, the AIADMK government, at the fag end of the term, has launched two more supercritical plants that could take four years to complete, going solely by the historical delay in commissioning of every plant in the past decade.
