GHG Emission Classification

Posted by BHARGAV JOSHI on August 25, 2011 at 12:26am in Ideas for Innovation

Hi

We are producing Electricity through Wind Energy and exported into State grid due to long distance between wind farm and Mfg. Facility. While using power from State grind we are also getting rebate for the same.

Does any one have idea How to classified & quantified  GHG Emission as per GHG protocol in this scenario?

 

As per my Idea

 

Power generated through wind farm(WE)- power used(PU) and difference is considered as emission into SCOPE 1 category?

 

2. How to reported emission from Bio mass consumption (sequestered carbon) in emission categorization(Scope-I/II/III)? there is no specific criteria in GHG protocol

    Hi

    Tnx for highlighing on GHG guidelines. I would like to clear my douts in depth so can u plz tell about below mentioned illustration?

     

    RE generated by company = 100 MW

     

    Use of RE = Export into State grid

     

    Use of State grid Electicity at Company's Mfg. facility=110 MW

     

    As per per my understanding based on our discusion is while accounting of GHG emission

     

    Inthis Scope 2 Emission = (110-100)=10 MW X EF

    (if company using same quantity of exported power from state grid then its consider as 0 Emission in Scope 2 Emission )

     

    M i right in this scenario?plz focus on this in depth with an illustration

    Location doesn't matter here. As the power being consumed is from Renewable energy source (i.e. Wind mill), GHG emission is always be zero.

     

    Use GHG emission factor of consumed power as a zero (power from RE source) and you can scope and add this GHG emission (which is zero) in your GHG inventory. (And it is your positive side that you are consuming GHG emission free power. Subsequently your entire carbon footprint will also reduce)

     

    This is considering that, your organization is wheeling clean power generated from wind mills (Generation site) to the manufacturing site (power consumption site), whatever is the geographical location. 

     

    Note: Currently wheeling only inside the state is permitted by electricity board. No inter-state wheeling is there.

    ok i got it but can u plz explain based on below example:

     

    Onganization Wind power generation =100 MW  (Exported into State grid)

     

    Use of power from State grid by Organization = 95 MW

     

    Both the places of orgaization is at different location.

     

    can you plz quantify GHg emission in scope wise manner (Assumed GHG Emission factor is 1)

    SHAILESH ISHWARRAO TELANG said:

    As Rohit said, for GHG emission quantification,  only purchased electricity (from other party) should be considered (without financial things) in scope 2.  As per the information provided by you, organization is wheeling power from the renewable energy source (in your case -wind mill) to the manufacturing facility where the electricity is being used.  As the power being used is from renewable energy sources,  you can demonstrate it as a Zero in your GHG inventory.

     

    In your case, you can add GHG emission as a 'zero' (Used units of power multiplied by zero as an emission factor) in scope 2.

     

    If the organization is using its power from the grid (without wheeling renewable power from the wind mill) then, the entire emission (positive value, multiplied by regional grid emission factor) comes in scope 2 as already described earlier -GHG emissions from purchased electricity that is used within an organizational boundaries should be included in scope 2 emission under the GHG protocol.

    Please keep emissions and rebates separate. The GHG emissions have nothing to do with the financial rebates government have given to you unless you are interested in getting carbon credits. In any case, the quantification will still remain the same as I told you, i.e. it remains Scope 2 Emissions.

    Hi


    My douts is

    If an organization is producing 100 MW of power through Wind Farm/any renewable energy source and exported into state grid due to long distance between Company's wind farm and Company's Mfg. facility.

    Company is getting 100 % rebate while using power from State grid because Company has already exported power into state grid.

     

    let me know in this case how to categorized and quantified  GHG emission from Electricity generation and Consumption?

    Hi,

    I don’t understand your query. As per your query, are you asking to include power generation from wind to scope one or what?

    Please provide following information;

    • Are you wheeling generated power from your wind mills to your manufacturing facility through state electricity grid?
    • If not, then are you using generic grid power in your manufacturing facility?

     

    Direct GHG Emissions: Direct emissions are emissions within your company’s organisational boundary from sources that your company owns or controls, like Energy generation by combustion of fuel, business travel in a company car or the combustion of fuel in pantry’s or kitchen located on your company’s premises . For reporting purposes direct emissions are called SCOPE 1 emissions.

    Indirect GHG Emissions: Indirect emissions result from your company’s activities but from sources owned or controlled by another company. For reporting purposes, indirect emissions are divided into the following two categories:

    SCOPE 2 emissions: refer to GHG emissions from purchased electricity, heat or steam that is used within a company’s organisational boundaries.

    SCOPE 3 emissions: are all other indirect emissions resulting from activities of the organisation but at sources not under the control of the organisation.

    Hi Bhargav,

     

    First of all, the power consumed is not Scope 1 emission; rather it is Scope 2, indirect emissions on which the consumer has a control.

     

    Secondly, biomass consumption is carbon neutral. Hence the net emissions due to biomass consumption is considered to be zero. Keep in mind however that this biomass has to be of renewable nature, i.e. it keeps on appearing (think crop residue that comes up each year or a plantation for the same purpose).
