Getting Market Ready: Costs, tariffs and business models in the EV charging market

Costs, tariffs and business models in the EV charging market

Although the development of the electric vehicle (EV) market has been marginal in India as compared to established markets in Europe, North America and China, it has gained notable traction in recent years. Various business models are being explored and tested for commercial viability. While India does not have any mature or proven successful business models for EV charging yet, so­me models are being tried widely, including public-private partnership (PPP), facilitation through discoms, urban local bodies (ULBs), power generators and public transport corporations set up by automakers. A mix of public and private charge point operators (CPOs) is currently leading the development of public charging infrastructure. A look at various business models being adopted for EV charging infrastructure …

Business models

Various business models have emerged for EV charging infrastructure, including ULB-operated infrastructure, PPPs, utility-anchored charging infrastructure, tra­nsport company, fleet operator and auto company owned and operated infrastructure. According to a Deloitte study, in the nascent Indian market, PPP-led and public transport corporation models are ideal as both risk levels and initial investments are low in these cases. Due to the limited availability of charging stations, fleet operators have also opted for setting up their own facilities. Moreover, at present, many CPOs and developers are taking initiatives to install captive charging stations in commercial spaces on their own to increase visibility, bring confidence amongst EV buyers and ad­d­ress the range anxiety issue to some ex­tent. Some of the business models:

Led by ULBs:  ULBs such as municipal corporations and area development au­thorities own and operate charging stations, while electric utilities provide the infrastructure and technical support. Some private entities can also be part of the collaboration to set up charging stations. For this, public land, aggregated from different government and public sector bodies, is provided for the installation of charging facilities. Under this set-up, the facility could operate at a fixed rate for park and charge, with revenue distributed between entities.

Led by public transport corporations: EV charging stations can be set up at areas designated by public transport corporations such as bus depots and parking lots. These can help meet charging demands of the electric fleet. Under this set-up, cab and autorickshaw aggregators will pay the utility charging fees.

PPP: A private entity is responsible for financing the ch­ar­ging station installation, operations and maintenance in this model and the utility takes care of the land and electricity infrastructure. The charging rate is fix­ed using a competitive process and both investment (except land) and revenue risks are borne by the private operator. Wi­th a fixed charge, irrespective of the ut­i­lisation rate of the charging station, electric utilities are assured a fixed revenue.

Anchored by discoms: In this model, an electric utility or discom owns the char­ging station and operates it either directly or through their franchisees (or con­tra­ctors). Charging facility assets fo­rm part of the regulated assets of the discom, which is responsible for the electricity distribution as well as operations and maintenance of the facility.

Facilitated by transport aggregators or corporates: Fleet operators require char­ging facilities for their EV fleets. In this case, land is provided by the fleet operator, who may own or lease it. The adoption of e-fleets is witnessing an increasing trend across big corporations. The need to meet sustainability targets and dema­nd from employees mean fleet managers are turning to EVs. However, the business case of fleet EV adoption is a key driver. The advantages of this model include low maintenance costs, attractive utilisation rate of charging points, thus making the investment viable.

Owned by charge point developers: A CPO installs and maintains charging stations, so that drivers can charge their EVs. In this, CPOs can either own and operate a set of charging stations, or simply operate them for third parties. The operational role of the CPO involves purchasing charging stations, installing hardware and maintaining the network connection. The operator is also involved in setting prices for charging infrastructure use and managing the connection to e-mobility service providers.

Initiatives being taken in the Indian market

Currently, Energy Efficiency Services Li­mited’s (EESL) subsidiary, Convergence Energy Services Limited (CESL), is supporting the roll-out of public charging infrastructure in India. In a recent development last month, CESL announced the list of selected agencies for the installati-on of 124 battery swapping stations, 352 standing chargers for electric two- and three-wheelers and 1,294 standing DC fast chargers for electric four-wheelers ac­ross eight cities. These will be built un­der a build-own-operate model valid for eight years. Under this tender, CPOs will be given a right to use the sites provi­ded to them by CESL for setting up and operating the charging infrastructure in the area. This business model is a shift from the earlier mode of business where CESL was responsible for investing, owning and operating these stations. With this tender, CESL has under implementation 1,770 EV charging stations. Apart fr­om EESL, various other PSUs such as NTPC Limited, Rajasthan Elec­tronics and Instruments Limited and Bharat Heavy El­ec­tricals Limited have announced plans to implement EV char­ging stations on a massive scale across the country. Meanwhile, oil PSUs that are seen to be in a strategic position to build charging inf­rastructure, especially on highways and ex­pressways across the country, are lett­ing CPOs set up their charging stations at retail outlets. Oil ma­rketing companies such as Indian Oil Co­rporation Li­mited, Bharat Petroleum Corporation Li­m­i­ted and Hindustan Pet­roleum Corpo­ration Limited have ple­d­ged to use their outlets to cumulatively set up 22,000 EV charging centres by 2025. Discoms such as BSES, Tata Power Delhi Distribu­tion Li­mited and Bangalore Electricity Supp­ly Com­pa­ny Limited are proactively partnering with several market players for setting up charging stations and bat­te­ry swap points in their areas of operation. The National Highways Authority of India is also working closely with the government to build charging infrastructure on national highways. It plans to cover 35,000-40,000 km of national highways, with charging stations, by 2023. Addit­io­nally, charging station network developers such as Fortum, Magenta Power, Volttic and TecSo Charge Zone have developed their own charging platforms for managing their EV charging networks. Further, vehicle original equipment manufacturers (OEMs) are collaborating with CPOs for providing existing and upcoming buyers with assurance regarding public charging points. For instance, vehicle OEMs such as Hero Electric, BYD India and Ather Energy have tied up with CPOs such as Charge Zone and Magenta ChargeGrid.

Tariff design and policy support

There is significant variation across sta­tes in terms of tariff design. A few states have introduced demand charges, which inc­lu­de Gujarat, Haryana, Karna­taka and Ma­harashtra, while some states have no­ti­fied only energy charges, such as Andh­ra Pradesh, Delhi, Chhattis­garh, Telan­ga­na and Uttar Pradesh, among others.  Each state sets its own rates for distinct consumer groups, therefore, the two sides of the tariff, energy and demand ch­ar­ges, differ from one another. The fixed or demand charge for an electricity connection is levied on the sanctioned load for the connection or the maximum po­wer demand registered during the billing period, which must be paid irrespective of the actual power us­age. Ener­gy charges are the variable com­ponent of an electricity tariff, applied on the total volume of energy/electricity co­ns­umed during the billing period. Fur­ther, in Jan­uary 2022, the Ministry of Po­wer issued revi­sed guidelines with the intent of channelling private investment towards EV charging infrastructure and ensuring that EVs are charged at competitive tariffs. According to these guidelines, tariff for electricity supply to public charging stations (PCSs) will be a single-part tariff and will not exceed the average cost of supply until March 31, 2025. The same tariff will be applicable to battery charging stations. Also, the tariff applicable to domestic consumption will be applicable to domestic charging. There will be a separate metering arrangement for PCSs, so that consumption may be recorded and billed as per tariffs for EV charging stati­ons. Discoms may leverage funding from the revamped distribution sector pro­g­ramme for the general up­str­eam network augmentation necessitated by upcoming charging infrastructure in various areas. As per new guidelines, land available with the government or public entities will be provided to install to a government or public entity on a revenue sharing basis at the fixed rate of Re 1 per kWh.

The way ahead

In sum, multiple EV charging business models are available at present, in the same region and/or city. The industry will have to adopt the model that best meets its requirements and will also have to come up with innovative models, going forward, to adapt to the changing market dynamics.
