Consideration in sec 2(31) in gst

It is not part of consideration. Hence it will be not included in value supply u/s 15 except it has been received from wherever other than goverment i.e Central and State. so Partly GOVERNMENT ENTITY OR SECTOR OR UNIT NOT COVERED IN GOVERNMENT.

Subsidy is not Atract GST and also in previous Taxes...

A state-owned enterprise in India is called a public sector undertaking (PSU) or a public sector enterprise. Those companies are owned by the union govt of India  or one of the many state or territorial governments or both. The company Stock needs to be majority-owned by the government to be a PSU. PSUs strictly may be classified as central public sector enterprises (CPSEs) or state level public enterprises (SLPEs).

So PSU is definitely cover under Govt Concern.

Now come to your Query , What is Subsidy ???? The subsidy is not defined in GST , but it's kind of Inventive or schemes offered by Govt for the growth & development of business . So the lawmakers have amply cleared that there shall not be any Taxability on subsidies being provided by state or central Govt & the same has been cleared by Section 15(e) of CGST Act , that subsidy provided by govt shall not be included in value of supply.

Hence Any subsidy being provided by govt shall not be included in the value of supply

IF Subsidy 

directly linked to price 

and 

received from any person other than Govt. (CG/SG)

then it shall be part of Consideration 

strictly interpretation of law is saying that subsidies received from any person other than Central Govt OR State Govt shall be part of Consideration.

in your case , it shall be included (my interpretation) 

It is not part of consideration.
