Kerala’s new draft ordinance improves forecasting and scheduling of wind-solar hybrid projects

The Kerala State Electricity Regulatory Commission has tabled a draft regulation to improve forecasting and scheduling of hybrid projects in Kerala. The initiative is a significant step towards optimizing the integration of renewable energy sources, ensuring grid stability and improving overall energy management in the state.

The draft regulation defines hybrid projects as those that combine different renewable energy sources, such as solar and wind, to generate electricity. The main objective of this regulation is to ensure accurate forecasting and scheduling of energy generation from these hybrid projects in order to maintain a balance between supply and demand, which is crucial for the stability of the power grid.

A key aspect of the draft regulation is the requirement for hybrid project developers to submit detailed generation forecasts. These forecasts must be prepared day-ahead and intraday, allowing grid operators to predict how much electricity will be generated and adjust their operations accordingly. This proactive approach helps mitigate the inherent variability and intermittency associated with renewable energy sources.

The regulation mandates the use of advanced forecasting tools and techniques to improve the accuracy of generation predictions. Developers are required to use weather forecast models, historical generation data, and other relevant factors to generate accurate forecasts. This level of detail and accuracy is expected to reduce the number of grid imbalances and provide more reliable electricity supplies to customers.

In addition to forecasting, the regulation emphasizes the importance of scheduling. Hybrid project developers must provide a detailed schedule of projected generation to the State Load Dispatch Center (SLDC). This schedule should include information on projected generation for each 15-minute time block during the day. By providing this level of detail, the SLDC can make informed decisions about power dispatch, thereby maintaining grid stability.

To enforce compliance, the draft regulation includes provisions for penalties in the event of significant deviations between forecasted and actual generation. If actual generation deviates from a specified threshold, developers may be subject to penalties. This measure aims to encourage developers to invest in accurate forecasting and planning technologies and practices.

In addition, the draft regulation outlines the responsibilities of the various stakeholders involved in the process. The SLDC is tasked with monitoring the forecasts and schedules submitted by developers and taking necessary actions to manage any discrepancies. On the other hand, developers are responsible for ensuring the accuracy of their forecasts and adherence to the schedules provided.

The regulation also emphasizes the need for capacity building and training programs to increase the skills of forecasting and planning personnel. By equipping them with the necessary knowledge and tools, the state aims to improve the overall efficiency and effectiveness of its renewable energy integration efforts.

The introduction of this draft ordinance is a significant milestone in Kerala’s journey towards a more sustainable and resilient energy system. With a focus on accurate forecasting and scheduling, the state is taking proactive steps to address the challenges arising from the increasing penetration of renewable energy sources. This ordinance not only ensures grid stability but also promotes optimum use of renewable energy, thereby contributing to Kerala’s renewable energy goals and reducing its dependence on conventional fossil fuel-based power generation.

The Kerala State Electricity Regulatory Commission’s Draft Regulation on Forecasting and Planning of Hybrid Projects is a forward-looking initiative that addresses the complexities of integrating renewable energy into the power grid. Through accurate forecasting, detailed planning and stringent compliance measures, the regulation aims to enhance grid stability, ensure reliable electricity supply and promote efficient use of renewable energy resources in Kerala.
