FOR INSTALLATION OF ROOF TOP SOLAR PV POWER PLANTS UNDER NET METERING POLICY IN PUNJAB

WHAT IS NET METERING ?

Net metering is the process through which you attain a “dual – benefit “by installing a solar power plant on the roof, open space, walls of the building to generate electricity. The generated power is first used in the building as per the requirement, even at the time of power cuts and the surplus power is fed into the grid of utility (PSPCL).

KNOW THE DUAL BENEFIT ?

A bi-directional meter is installed in the supply line to register import and export of power. Net metering arrangements, thus, combine elements of captive power consumption and exchange of power with the utility. The bill is issued by utility (PSPCL) after adjustment of import and export of power.

DO YOU WANT TO INSTALL

Under Net Metering policy, all consumers of electricity having minimum sanctioned load of more than 1.25KW and who intend to generate their own electricity and willing to contribute towards environmental protection can install Solar PV plants on Roof-Tops/ Walls/Open area of individual households, industries, commercial establishment, institutions, residential complexes, schools, colleges, hospitals, sheds, cold stores, govt. and semi-govt. buildings, etc.

Know your Capacity range:

Under Net Metering Policy, Solar PV power projects of capacity ranging from 1KW to 1000KW can be installed. The maximum capacity of solar power plant to be installed in the building would be 80% of the sanctioned electricity load of that building.

Why to Adopt Net Metering

  • Reduction in bill, as the bill is issued by PSPCL after adjustment of export and import of power.
  • Generation of environment friendly, clean energy. Monthly minimum charges would not be leived by PSPCL.
  • Consumer becomes generator for his own electricity requirements.
  • Reduction in electricity consumption from the grid.
  • If exported power is more than the consumed power then it would be accounted and set-off in the settlement period of October to September.
  • The electricity duty/octori etc shall be levied only on the billed amount after adjustment of import and export of power.
  • Continuously supplies power to the building during power cuts through battery bank.
  • Surplus power is supplied to the grid of PSPCL, thus, helps in eliminating power shortage.

MNRE, GOI subsidy:

Under the scheme MNRE, GOI provides 30% subsidy for installation of solar power plants of capacity ranging from 1 KW to 500 KW

Roof Top Area, Total cost & Subsidy:

1KW = 120 Sqft.
Approximate cost of 1KW = Rs. 57,751/-
Govt. Subsidy 30% = Rs. 17,325/-
Beneficiary Share 70% = Rs. 40,426/-
For higher capacity plants, Area, cost, subsidy and beneficiary share would be in proportion to the size of the plant
Economics & pay back calculationPayback period of beneficiary share of Rs. 211815:
  • Plant capacity    – 5kw
  • Plant cost     – Rs. 2,88,755/-
  • Subsidy @ 30%    – Rs. 86,625/-
  • Beneficiary share     – Rs. 2,02,130/-
  • on the basis of current power tariff slab if average monthly electricity bill of 3 bed room house is 800 Units.     -Rs. 5383/-
  • FY 2018-19 annual saving – Rs. 5,383X12 = Rs. 64,596/-
  • FY 2019-20 annual saving – Rs. 5,652×12 = Rs. 67,824/-
  • FY 2020-21annual saving – Rs. 5,934×12 = Rs. 71 ,208/-
  • FY 2021-22 annual saving – Rs. 6,230×12 = Rs 74,760/-

TOTAL = Rs. 2,78,388/-

Payback period = 4 year

Calculation is based on 5% average yearly escalation in power tariff

Energy calculations for different types of Houses :

lllustration-1 : 2 bedroom house:

  • Plant Capacity – 2 Kw
  • Daily generation – 8 units
  • Monthly generation – 240 units
  • Average monthly electricity consumption – 300 units (approx.)

In Punjab domestic tariff slab :

♦ 0- 100 units -Rs. 4.98/ unit

♦ 101- 300 units – Rs. 6.55/ unit

♦ 301 and above – Rs. 7.15/ unit

So after adjusting the net consumption and net generated units of power, the average electricity bill during the month shall be calculated as under:

♦ 0-100 units =100×4.98 – Rs. 498/-

♦ 101- 300 units = 200×6.55 – Rs. 1,310/-

♦ Total – Rs. 1808/-

Generation of Solar PV Plant shall be accounted for as under:

♦ First 200 units = 200×6.55 – Rs. 1,310/-

♦ Next 40 units = 40×4.98 – Rs. 199/-

♦ Average monthly saving on energy bill – Rs. 1,509/-

♦ Net Bill – Rs. 299/-

Illustration-2 : 3 bedroom house with 1 AC:

  • Plant Capacity – 5Kw
  • Daily generation – 20 units
  • Monthly generation – 600 units
  • Average monthly electricity consumption – 800 units (approx.)

In Punjab domestic tariff slab :

♦ 0 – 100 units – Rs. 4.98/ unit

♦ 101 – 300 units – Rs. 6.55/ unit

♦ 301 and above – Rs. 7.15/ unit

So after adjusting the net consumption and net generated units of power, the average electricity bill during the month shall be calculated as under:

♦ 0 – 100 units =100×4.98 – Rs. 498/-

♦ 101-300 units = 200×6.55 – Rs. 1,310/-

♦ 301 and above = 500×7.15 – Rs. 3,575/-

♦Total – Rs.5,383/-

Generation of Solar PV Plant shall be accounted for as under

♦ First 500 units = 500×7.15 – Rs.3,575/-

♦ Next 100 units = 100×655 – Rs.655/-

♦ Average monthly saving on energy bill – Rs.4,230/-
