Spotting the Barriers in Renewable Transmission


With the installed renewable energy capacity of 83,000 MW and 66,000 MW under execution and bidding respectively, India’s renewable energy precis looks promising. In addition, a recent report by Central Electricity Authority (CEA) states that India’s total installed power capacity is projected to be around 480 GW by the end of 2021-22. The country’s transmission infrastructure for the evacuation of clean power, however, is still in a fragile state. Even though the central government’s green energy corridor (GEC) initiative is being established, there are certain hurdles that need to be crossed for a reliable renewable transmission system in the country.

Challenges in setting up evacuation infrastructure:

As compared to setting up a solar or a wind project, which takes almost 12-18 months, establishing a transmission infrastructure can take as much as five-six years. One of the biggest challenges is to ensure that before the completion of renewable projects, proper transmission projects are already in place. Let’s have a look at some of the prime challenges in the way of a reliable renewable transmission system.

·      Opposition from public

With the global focus inclined towards more and more clean energy sources, the construction of renewable energy (RE) facilities is significant. However, while doing so just limiting the emission of greenhouse gases isn’t enough. It is important that the new transmission establishments are not violating the sustainability aspect like causing harm to endangered species, reducing property values or other RoW issues. Such obstructions can cause indefinite delay to the completion of the project. This issue can be resolved by involving the respective stakeholders early in the decision-making discussions. Educating the stakeholders about the bigger picture of how RE can solve the energy & global warming challenge and the employment growth opportunities that comes with transmission infrastructure is required. This will help in the generation of greater support for projects.

·      Insufficiency in grid infrastructure

New transmission infrastructure for the future RE projects are already under approval. However, the issues with the existing grid infrastructure must be addressed. To begin with, there is still a large gap between the development of transmission infrastructure and clean energy tenders. There have been instances when the tenders have been released without prior consultation with the SERC – state electricity regulatory commission. At present most of the power purchase agreements (PPAs) are kept on hold due to the lack of proper transmission infrastructure.

·      Backing down of power by grid operators

Due to various technical constraints such as variability of resources, unpredictability and location dependence, generation of RE, especially wind and solar energy are being backed down. Such instances lead to financial losses for the clean energy generators, as at present there is no provision of providing compensation for ‘deemed generation’.

For the renewable energy scenario in India to be robust, it is important that the transmission infrastructure of the country is built quickly, failing which, the RE bandwagon might derail.

POWER TRANSMISSION: THE KEY TO INDIA’S SOLAR MISSION

Image
The year 2016 will be remembered as the tipping point for solar energy. For the first time, it became cheaper to produce your own electricity than to buy it from the grid! Prime Minister Narendra Modi could not have asked for a better timing. The sharp drop in solar prices perfectly coincided with his first term. His government’s vision of adding 100 GW of solar generation capacity may in fact materialize as early as the year 2022. What’s more, the macro environment for solar power looks poised for an upsurge. India has an abundance of the two most critical elements for solar power – land and sunshine. Get more information  sterlite power transmission limited There is easy availability of affordable solar panels in China, while global developers are now quoting about 7 US cents per unit (Rs. 4.5 / kWh) to build, own and operate solar farms in India. Therefore, it seems as if nothing can stand in the way of India’s charge towards solar power. However, the power...

Upgrading Power Transmission Lines To Higher Voltage With Existing Infrastructure

Due to increasing urbanization and industrial growth, energy consumption has gone up in Tier I and Tier II cities in India. The rising population, along with the government’s focus to provide uninterrupted electricity to all homes by 2019, is projected to increase electricity consumption five to six times between 2014 and 2030. Over the last few decades, India has witnessed a steep rise in generation capacity. With government’s efforts, even if half of the planned renewable capacity gets installed by 2022, the generation would certainly match the nation’s requirement. Get More Detail at  electrical power cable However, the key to this fulfillment will be to match generation capacity addition with adequate power transmission and more importantly, intrastate transmission and the sub-transmission network. This network must be made available to enable the downstream to the load centers around densely populated urban areas of important states and industrial areas.  Und...
