Broadening Definition of Green For Transmission Assets
With the headline focus on renewable capacity creation, generation, storage, and now hydrogen, it is time the transmission structure was also placed in the same spotlight.
Citing the current taxonomy, by the EU, which only considers transmission and network to be green if stringent criteria are met, such as having CO2 emissions intensity below a certain level the authors make the case to include "essential upgrades to the existing network, expansions to create parallel paths that ensure reliability, and smart grids that ensure security of the grid. Additionally, the timeframe allowed for planning is too short to see the long-term benefits of transmission lines, which have a lifespan of at least twice as long. Therefore, it is necessary to address these flaws in the methodology to prioritize transmission planning and achieve decarbonization goals."
In their working paper, they propose a methodology that combines elements of generation and transmission planning and provided motivating illustrative examples that may help to appreciate a broader definition of green transmission. By allowing transmission finance the same benefits as green finance, the probability of easing the shift to green energy, particularly in heavily coal powered economies like India, Indonesia, Kazakhstan, and South Africa will improve significantly, the authors argue.
The viewpoint of the writers articulates a very important issue across the world. Transmission infrastructure, which should really have been addressed along with the large shift to renewable energy a decade or more ago, is only gaining attention now when it is repeatedly turning up as the issue that matters. In India too, we have seen how many state discoms have actually resisted higher renewable power under the pretext of disruption to the transmission infra or even stability of the same. These arguments have worked far too many times with regulators to allow them more time, or delay projects.
One only has to look at the wide variation in valuations and project appraisal, when the power buyer from a renewable energy generator is a central entity like SECI or even NTPC, versus most state discoms, to understand the real financial shadow it casts on projects.
The urgency with which efforts are being made to redress the financial challenges of these discoms also indicates that the government recognises the issue. We certainly agree with the original premise here, to allow more climate finance to flow unhindered to transmission utilities too, as long as it expands and strengthens the grid to handle green energy better.
