Open Access Power refers to a regulatory mechanism that enables grid-connected bulk consumers with a contract demand of 1000 kVA or above to fulfil a part or all of their electricity requirements through alternative energy sources.
There are two primary power procurement models used in Open Access:
a) Third-Party PPAs: In this model, a third-party investor or solar developer invests in an Open Access project and sells the power to corporates through a Power Purchase Agreement (PPA). The corporate buyer pays Open Access charges incurred from the wheeling of power to their location.
b) Captive/Group Captive Model: In the captive model, the corporate buyer makes an upfront capital investment in the Open Access project and owns, operates, and maintains the power-generating asset. Open Access charges, such as cross-subsidy surcharge and additional surcharge, are waived off. The group captive model involves multiple corporate buyers collectively utilizing an Open Access project.
Open Access charges in utility-scale renewable projects vary depending on location and procurement models. The charges include:
• Transmission charges: Payable to the transmission company for using the transmission infrastructure.
• Wheeling charges: Payable to the distribution company for using the distribution network.
• Transmission losses: Electricity losses in the transmission line between generation and consumption points.
• Wheeling losses: Electricity losses incurred by the distribution network.
• Cross-subsidy surcharge (CSS): Payable by commercial and industrial buyers to fund tariff subsidies for agricultural and residential consumers.
• Additional surcharge (AS): Imposed to recover the cost of standard assets when buyers leave the distribution company and procure power through Open Access.
• Banking charges: Charges for banking power generated but not immediately consumed, subject to state-specific regulations.
• Conduct due diligence based on company locations to assess grid power tariffs, state-level regulations, Open Access charges, and renewable resources.
• Understand Open Access risks, evaluate access to the grid and favourable Open Access charges, and assess potential regulatory changes.
• Perform due diligence on the developer’s experience, long-term interest, and financial strength.
• Negotiate the PPA by leveraging the buyers’ market, consider competitive tenders, and balance risk mitigation with cost optimization.
• Contractual Challenges: Tenor mismatch between PPA and loan, contract enforcement, and lack of standardized contracts.
• Operational Challenges: Grid curtailment risk, performance risk due to inexperienced developers, and ensuring power generation as per contracted terms.
• Regulatory Challenges: Uncertainty around Open Access regulations and charges, inconsistency in eligibility and operating criteria, exclusion of small consumers, and delays or refusals in obtaining Open Access permissions.
Yes, the current paper-based approval process can be improved by implementing a digital process that enhances transparency and efficiency. Online approval processes across multiple states, utilities, system operators, and regulators can expedite decision-making and reduce process time.
