The Green Energy Corridor project is a major initiative by the Government of India to promote grid integration of renewable energy and transmission of large quantity of energy from renewable sources located in resource rich regions to energy deficit areas. It was launched in 2015 with the aim of evacuating over 50 GW of renewable energy by 2022.

Wind and solar power projects are often located in remote locations far from load centers due to availability of abundant renewable energy resources. This poses significant challenges for integration of the renewable energy into the grid and its transmission over long distances to demand centers. The existing power transmission infrastructure in India was primarily designed to carry power from large fossil fuel power plants located near cities and towns. It was not equipped to handle bulk power from renewable energy projects located in dispersed rural areas.

The Green Energy Corridor project aims to address this issue by strengthening the transmission network and setting up new transmission lines that can facilitate grid integration of renewable energy projects and carry renewable power across states to major consumption centers. It involves building about 10,000 circuit kms of transmission lines along with upgrading 28 gigawatts (GW) of existing grids and creating new grids of 26 GW capacity across seven renewable energy rich states by 2022.

The impact of this ambitious project on renewable energy financing has been highly significant. By developing a strong pan-India ultra high voltage transmission superhighway exclusively for renewable energy, it has boosted investor confidence in the sector. The key impacts are as follows:

It has substantially reduced infrastructure related risks which were a major hurdle for large scale investments in renewable projects earlier. With the green corridor in place, developers now have assurance that there will be no issues of power evacuation or transmission bottlenecks once projects are commissioned.

Foreign and domestic institutional investors are showing greater interest in funding large utility scale renewable projects knowing that connectivity to the national grid has been significantly enhanced. This has resulted in bigger ticket sizes of renewable investments.

Financing costs have come down substantially as lenders perceive renewable projects as less risky given the robust offtake agreements through central/state utilities and the green corridor ensuring smooth power transmission.

Risk perceptions related to land acquisition, environmental clearances and obtaining transmission connectivity approvals have reduced. This has made under-construction projects more bankable and helped the renewable sector attract debt financing at lower interest rates.

Viability of projects located in remote resource rich areas but far from demand centers has improved multi-fold. The corridor creates new renewable energy zones and greatly expands geographical areas suitable for large scale renewable development across the country.

State-run Power Finance Corporation and REC Ltd. have become more aggressive in lending to renewable projects with assurance of bulk power evacuation. Their overall lending portfolio to clean energy space has grown significantly post the green corridor announcement increasing total investments.

It has created conditions conducive for development of ultra mega renewable parks. Investment proposals for setting up solar and wind parks with capacities of 5000-10,000 MW each have been announced based on availability of strong transmission network to handle bulk power generation.

The green corridor acts as a major catalyst to help India achieve its ambitious target of having 175 GW renewable capacity, including 100GW of solar and 60GW of wind power, by 2022. By facilitating large scale, grid-connected renewable energy deployment across key states, it aims to make clean energy the mainstay of India’s energy security and ease pressure on limited fossil reserves.

The Green Energy Corridor project has boosted investor confidence in renewable energy sector tremendously by resolving the infrastructure bottlenecks on power evacuation side. It is enabling a scale and geographical spread of renewable investments in the country that would not have been possible otherwise. It has put India on track to becoming a leading global producer of renewable power.

One of the major challenges faced in developing renewable energy projects is acquiring the necessary land area to install the required infrastructure. Renewable energy technologies such as solar farms, wind farms, and hydroelectric projects require large amounts of relatively undisturbed land space to implement on a utility scale. The land acquisition process can be difficult, time-consuming, and expensive which delays projects and increases costs.

For solar and wind farms, the footprint needed per megawatt (MW) of installed capacity is significant. A typical solar farm may require 5-10 acres of land per MW while a wind farm generally needs 150-250 acres per MW. With the goal of deploying hundreds of MW or even multiple gigawatts (GW) of renewable capacity, land needs escalate quickly. Finding contiguous parcels of land that are suitable in size, have access roads and transmission infrastructure, and have no environmental or community constraints is a major challenge.

Ownership of suitable land parcels is also an issue as renewable energy companies must negotiate with private landowners to lease or purchase the rights to develop projects. Private landowners do not always want to sell or lease portions of their property for renewable energy use which limits options. Agricultural or rural land is often the most economical for renewables but farmers and ranchers may be hesitant to remove acres from production. Cultural attachment to family land also acts as a deterrent at times.

When suitable publicly owned land is available, new challenges emerge. Federal, state, or local government entities oversee public lands and require extensive approvals, environmental reviews, stakeholder engagement processes, and competitive bidding between renewable energy developers. Even if a developer is selected, public agencies are sometimes criticized for “selling off” public assets or impacting viewsheds and recreation. Local communities also raise concerns about impacts to ecosystems, heritage sites, and rural character.

Transmission capacity is another major barrier as renewable energy facilities are often sited in remote or rural areas far from existing transmission lines and population centers where the power is needed. Acquiring rights-of-way and traversing private lands to build new transmission infrastructure to intertie projects adds time, complexity and cost to land development efforts. Transmission siting is governed by a complex federal, state, and sometimes local regulatory framework which slows the process down significantly. Interconnection studies and upgrades at substations must also be planned.

State and local level regulations can also hinder land acquisition. Some jurisdictions have imposed moratoriums on certain types of renewable energy development until new siting and permitting guidelines are established. Comprehensive plans and zoning ordinances need revisions to openly accommodate utility-scale renewable facilities. Restrictive setback distances from property lines, environmentally sensitive areas, or residential zones limit development options. Other regulations addressing decommissioning plans, stormwater management, and cultural/historic resource protection introduce uncertainty.

Environmental review and permitting processes take considerable time. Regulators thoroughly assess impacts to wildlife habitats, endangered species, wetlands, water resources, archaeological sites, and more before approvals are granted. Previously undisturbed greenfield sites usually face greater regulatory hurdles than already developed industrial lands. Legal challenges and appeals from opponents anxious to “not in my backyard” types of projects further protract the timeline.

Weighing all these challenges, it typically takes renewable energy developers 3-7 years on average just to acquire land, obtain permits and approvals, build new transmission infrastructure, and start construction of a major utility-scale renewable project. The lengthy process drives up soft costs significantly and challenges the economic viability of projects. Innovation in siting strategies, streamlined regulations, transmission coordination, and communitybenefits agreements have helped to accelerate development in some areas but land acquisition remains one of the most complex barriers for renewable energy. With sufficient political and social will, many challenges could be overcome or mitigated to unlock more suitable lands for large-scale clean power generation.

HOW DO OFFSHORE WIND FARMS COMPARE TO OTHER RENEWABLE ENERGY SOURCES IN TERMS OF COST

Leave a reply

Offshore wind farms have higher upfront capital costs for development and construction compared to many other renewable technologies due to the associated marine infrastructure requirements such as specialist installation vessels, foundations, underwater cables, and high voltage transmission connections to shore. The specialized heavy-duty turbines also have higher price tags than solar panels or simpler onshore wind turbines. Offshore locations allow the use of larger and more efficient wind turbines that can fully take advantage of the stronger and more consistent winds available out at sea.

A recent report from the International Renewable Energy Agency estimated the levelized cost of energy from offshore wind farms constructed in 2020 to range between $53-84 per MWh compared to just $32-42 per MWh for onshore wind, $36-46 per MWh for solar photovoltaic, $15-30 per MWh for hydropower, and $12-15 per MWh for geothermal energy. The costs of offshore wind have been steadily declining as the technology scales up and larger more efficient turbines are deployed in deeper waters further from shore where wind resources are better. Some recent auctions and power purchase agreements have come in well below $50 per MWh even for projects to be installed in the early 2020s.

As the technology matures and supply chains develop the costs are expected to continue falling significantly. Blooomberg New Energy Finance predicts that by 2030 the costs of electricity from offshore wind could drop below $40 per MWh on average globally and potentially below $30 per MWh in the most competitive markets like parts of Northern Europe and Asia. This would make offshore wind cost competitive even without subsidies in many locations compared to new gas-fired generation. Offshore wind is also projected to decline faster in price than any other major renewable energy source over the next decade according to most analysts.

In addition to lower operating costs over time, offshore wind farms have a major advantage over many other renewables in their more consistent year-round generation profiles with output peaking during winter months when electricity demand is highest. Output is also more predictable than solar due to capacity factors averaging over 40-50% compared to just 15-25% for photovoltaics. The steady offshore winds mean generation matches energy demand profiles better than intermittent solar or seasonal hydropower resources without costly grid-scale battery storage.

Reliable round-the-clock energy from offshore wind coupled with growing abilities to forecast weather patterns days in advance allows power grid operators to effectively integrate significantly larger shares of this clean generation into electricity systems than highly variable solar and maintain higher standards of grid stability and reliability. Offshore sites have fewer space constraints than land-based projects and can potentially be located near heavily populated coastal load centers in markets like Europe and East Asia to minimize transmission expenses.

Offshore wind projects require an extensive multi-year development and construction process unlike the quicker installation timelines for solar farms. This means higher upfront financing costs and risks that get priced into the initial levelized costs per kilowatt-hour calculations compared to less capital-intensive onshore renewables with simpler development procedures. Challenging offshore conditions and geotechnical uncertainties also introduce construction difficulties and greater risks of delays and cost overruns versus land-based facilities. Accessing deepwater locations further from shore for the best wind resources also increases complexities and costs.

Overall while upfront investment costs are higher, offshore wind power is projected to become significantly more cost competitive by the end of this decade as technology improves, supply chains scale, and multi-gigawatt projects are deployed. Key advantages in capacity factors, grid integration, and location attributes position it favorably versus alternatives like utility-scale solar photovoltaic and seasonal hydropower resources especially in coastal markets with strong energy demand like in Europe and parts of East Asia. With power purchase costs likely falling below $50 per MWh at many auctioned projects by 2025, offshore wind will establish itself as one of the lowest-cost renewable energy sources for leveraging oceans to help transition electricity grids to carbon-free systems in the decades ahead.

HOW CAN INDIA ENSURE LONG TERM STABILITY IN ITS RENEWABLE ENERGY POLICIES TO ATTRACT PRIVATE SECTOR PARTICIPATION

Leave a reply

India has made commendable progress in scaling up renewable energy in recent years. To achieve its ambitious target of 450 GW by 2030 and meet the energy needs of its growing economy, it is crucial that it ensures long-term stable and predictable policies. Only then will there be increased confidence among private players to invest significantly in renewable capacity addition. Some key measures that India can take are:

Formulate a comprehensive long-term national renewable energy policy with clear long-term goals for at least 10-20 years. The current policies have 5-year targets which do not provide enough certainty. A long-term policy will signal intent and direction. It should lay out a planned transition away from fossil fuels over 20-30 years. This will boost investor confidence that policies will remain stable over the long run.

Continue with schemes like competitive bidding through reverse auctions but ensure auction targets are well-staggered over 5-10 years to avoid boom-bust cycles. This will provide a steady pipeline of projects for developers and component manufacturers to invest in. Flexibilities may be introduced to factor in future cost reductions and technological changes.

Phase out all direct subsidies and move to a fixed-feed in-tariff (FIT) regime determined through auctions for different renewable resource zones. Staggered long-term FIT contracts of 15-20 years should provide assured returns. This will reduce risks for investors and banks, and attract more competitive bids. Contracts can be linked to inflation to ensure tariffs remain attractive.

Establish an independent national Renewable Energy Regulatory Commission on the lines of electricity regulators. This will provide long-term regulatory certainty and consistency in policy implementation. It can oversee auction designs, Power Purchase Agreements (PPA), grid connectivity etc. to make the system more transparent and attractive.

Simplify and streamline clearances and approvals through a single-window system. Liaise with state governments to expedite land acquisition, transmission infrastructure development and grid connectivity approvals. Ensure dispute resolution mechanisms are strong to reduce delayed payments risks. This will significantly reduce project implementation timelines.

Bring tax and financing reforms through incentives like accelerated depreciation, concessional duties on equipment, green bonds etc. to make financing renewable projects more competitive vis-a-vis fossil fuels. Offer Viability Gap Funding for projects in resource-rich areas lacking infrastructure to kickstart development.

Build capacity through training programs to develop a skilled local workforce for maintaining renewable energy systems. Create dedicated credit lines and financing packages through institutions like IREDA and Green Energy Corridor projects to scale up R&D, manufacturing and project development capacity within India over the long-run.

Put in place robust mechanisms for forecasting and scheduling of renewable power. Invest heavily in modernizing the grid, energy storage and developing a national renewable energy grid to balance variability through inter-state connectivity. Stringent quality control and technical standards can boost consumer and installer confidence.

Promote domestic and global green finance through registration on global carbon exchanges, emission trading and labeling programs. Multilateral cooperation on just energy transition programs can leverage greater international financing support.

Undertake sustained IEC campaigns to build wider public and political support for long-term policy consistency. This will reduce policy risks from changes in government priorities over time. Long-term visibility and policy-level support is vital for attracting significant private investment in building new zero-carbon energy infrastructure and supply chains in India.

Implementing these comprehensive measures can power India’s renewable energy transition by providing the predictability, bankability and enabling policy ecosystem essential to unleash massive private sector involvement over the coming decades. With consistent long-term policies and a conducive investment environment, India has enormous potential to emerge as a global renewable energy leader and achieve its ambitious climate and energy goals through collaborative efforts of the government and private sector. This will lay the foundation for a more sustainable, secure and prosperous low-carbon future energy system.

CAN YOU PROVIDE MORE INFORMATION ON THE EUROPEAN UNION’S EMISSIONS TRADING SYSTEM AND ITS IMPACT ON RENEWABLE ENERGY DEPLOYMENT?

Leave a reply

The European Union Emissions Trading System (EU ETS) is a cap-and-trade system implemented in 2005 that aims to combat climate change by reducing greenhouse gas emissions from heavy energy-using industries in the EU, including power plants. Under the EU ETS, there is a declining cap on the total amount of certain greenhouse gases that can be emitted by installations covered by the system. Within this cap, companies receive or buy emission allowances which each allow emissions of 1 tonne of carbon dioxide equivalents. Companies can buy and sell allowances as needed in annual emissions trading auctions and on the secondary market. This creates a price signal encouraging greenhouse gas reductions where they can be made most cost-effectively.

The EU ETS has played an important role in driving the deployment of renewable energy sources across Europe. The carbon price signal created by the trading of emission allowances under the EU ETS incentivizes power generators to switch away from fossil fuel-based generation towards lower-carbon alternatives such as renewable energy sources. Several studies have found that the carbon price resulting from the EU ETS has increased the deployment of renewable energy capacity in the power sector across the EU. For example, a study by the European Environment Agency found that about 45% of new renewable capacity installed between 2008-2015 could be attributed to the impact of carbon pricing under the EU ETS. This effect is due to renewable energy sources such as wind and solar having very low marginal generation costs once invested, giving them a competitive advantage over fossil fuel generation as carbon prices rise.

The increased deployment of renewable energies under the EU ETS also displaces fossil fuel generation, contributing to emission reductions in the capped sectors. A study published in Nature Climate Change found that cumulative emission reductions due to renewable energy deployment driven by the EU ETS amounted to around 20 million tonnes of CO2 between 2008-2015. This displacement effect amplifies the overall impact of the emissions trading system on emission reductions beyond a simple cap-and-trade mechanism. The incentive for renewable energy provided by the carbon price is largely dependent on the stability and predictability of the price signal. Periods of low and volatile carbon prices, such as those seen in Phase 2 and Phase 3 of the EU ETS to date, undermine this effect to some extent.

The EU ETS also indirectly supports renewable energy deployment through specific provisions within the design of the system. For example, the EU ETS electricity sector benchmark used for free allocation distribution considers a renewable energy benchmark. This favors renewable generators who face no carbon costs and thus need fewer free allowances. Also, the directive establishing the EU ETS allows Member States to use revenues from EU ETS allowance auctions to support national renewable energy and energy efficiency measures. Many countries have implemented such ‘carbon pricing measures’ like UK carbon price support and Sweden’s carbon tax, with revenues dedicated to green energy goals. Estimates suggest up to 30% of renewable support spending across EU nations between 2008-2015 was financed through carbon pricing revenues. So in several ways, the design and operation of the EU ETS provides dedicated support for scaling up renewable electricity.

The emissions trading mechanism of the EU ETS has played a significant role in driving renewable energy deployment across the European Union over the past decade. By placing a price on carbon emissions, the EU ETS incentivizes the replacement of fossil fuels with lower-carbon alternatives like various renewable energy sources. Empirical analysis has shown over 40% of new renewable capacity installed since Phase 2 can be attributed to this effect. The displacement of fossil fuel use by renewables supported by the ETS also amplifies its emission reduction impact. While a stable and high enough carbon price is critical, features within the EU ETS that support renewable energy further increase its positive impact on deployment of clean energy alternatives across Europe’s power sector.
