AGL Chart Gone Parabolic, page-10

AGL seems to have some resistance.

Rachit Dudhwala reckons on TWR that
"Most Australian homes are connected to the electricity grid through contracts with retailers like AGL, Origin and EnergyAustralia (to name a few). These retailers buy electricity at regulated prices from the national energy market (the wholesalers: ORG, STO, WPL, SXY).
Electricity is provided to the national energy market by the generators (who generally own the power plants which convert raw fuels into electricity). In Australia, this is predominately dominated by AGL, Origin and French-multinational Engie.
These generators transmit electricity across the grid, into homes, using transmission and distribution networks owned by the likes of AusNet Services, APA Group, DUET Group and Spark Infrastructure Group (amongst others).
Whilst there is clearly a number of players in the electricity market, the looming shutdown of Hazelwood on 1 April 2017 means existing generators are set to make a killing as competition for electricity generation decreases.
In fact, the impending shutdown of Hazelwood has already sent electricity futures soaring to all-time highs with May 2017 contracts currently being settled at $151 per megawatt. This is in stark contrast to the average electricity price of $40 per megawatt obtained by the same generators this time last year.
Even more beneficial to electricity generators is the concept of “load shedding”. This is where power plant owners shutdown electricity generators to reduce supply to the energy market, in turn increasing the spot price of electricity and virtually allowing them to control market prices.
Whilst the practice is effectively a manipulation of market prices, no regulations prevent load shedding and therefore electricity generators are able to profit at the expense of wholesalers. This is a powerful position to be in."

Good for AGL sholders.
