REC Mechanism and Structuring Sale of Electricity for Benefit Maximization
Renewable Energy Certificate Mechanism provides few additional options to RE generators to structure their electricity sale to maximize their profit. Structuring the sale of electricity can play an important role in maximizing the benefits of a particular project. A Renewable Energy Generator can have multiple options to manage electricity sale. Each option has its own advantages and limitations. The options can be listed out as:
- Sale to DISCOM at Preferential Tariff: PPA with a DISCOM is a very basic option which can assure guaranteed ROI over a longer duration. This can be a benchmark to evaluate other options against.
- Sale to DISCOM at Average Power Purchase Cost: Sale to DISCOM at Average Power Purchase Cost can assure a guaranteed return with an additional income from GBI, but the tariff is low when compared to the preferential tariff. This drop in tariff can be compensated by additional revenue from RECs.
- Third Party Sale/ Open Access: Detailed analysis is required while going for Third Party Sale or Open Access as this may involve higher risks and other applicable charges as well. The charges may include Transmission Loss, Transmission Charges, and wheeling Charges. Cross Subsidy charges may also be eligible and will have a considerable effect on the price if implemented. The advantage with Third party Sale/ Open access is that the tariff may be comparatively higher and the generator is allowed to avail RECs as well.
- Captive/ Group Captive Consumption: Most of the states allows RE generators to consume electricity generated as a captive consumption by paying nominal wheeling and banking charges (in case of wind/small hydro). As per CERC regulation, when RE generation is used for captive consumption and promotional benefits are availed (promotional wheeling and banking), RE generator becomes ineligible to participate in REC mechanism.
REC vs CDM Mechanism
The below analysis was covered in a story by Bloomberg. You can read that article here. After the launch of Renewable Certificate Mechanism (REC) in India, a frequent question in the minds of project developers is the comparison between Clean Development Mechanism (CDM) and REC mechanism. The below section covers some of the questions regarding the eligibility for CDM and REC, and the relative benefits under both mechanisms. Q: Is a project eligible for REC benefit if it is already availing of CDM benefit? A: The REC and CDM mechanisms are independent of each other. REC is a national mechanism which is focused on renewable energy generation whereas CDM is an international mechanism which is focused on Green House gas abatement. Nowhere in its regulations the CERC has specified that availing of CDM benefit will disqualify a RE generator from accessing REC markets. Further, the CERC has clarified that “REC and CDM are different mechanisms” (Statement of Objects and Reasons dated January 14, 2010). Q: Is the project eligible for CDM benefit if it also avails the REC benefit? A: As mentioned above, the REC and CDM mechanisms are independent of each other, and from the CERC's perspective, can co-exist. However, one of the fundamental aspects of eligibility for carbon credits in the “Additionality” criterion*. If the additional benefit of RECs is considered (even at a minimum of Rs 1.5/unit), it is likely that several projects that meet the additionality criterion under CDM without REC, are likely to not meet the criterion in the future when REC benefit is included. However, for every project an analysis will have to be done on a case-by-case basis. For example, a project that meets the additionality criterion based on the feed-in tariff of a state, may still meet the criterion if the APPC + REC price is considered in one state, but not in another. Q: How does the benefit under CDM and REC mechanism compare? A: The benefit needs to be compared under various parameters:
| Options | REC | CDM |
|---|---|---|
| Monetary Benefits | More | Less |
| Access ( Profit/Cost ) | Less time | More time |
| Certainty of Revenue | Depends on enforcement of the mechanism | Reasonable |
REC Implementation Mechanism
Honourable Central Electricity Regulatory Commission (CERC) has been very active all throughtout the year for the implementation of REC mechanism in India. The Terms and Conditions for recognition and issuance of Renewable Energy Certificate for Renewable Energy Generation were notified and thereafter had its first amendment also.
