Co-located BESS initiative for RE generators under existing APDISCOM PPAs

By -

Expression of Interest (EOl) from Renewable Energy Generators having existing PPAs with AP DlSCOMs for installation of Co-located Battery Energy Storage systems (BESS) at their RE project sites in Andhra Pradesh.

Last date of submission extended to 17.08.2026

Objective: 

AP DISCOMs have long-term Power Purchase Agreements (PPAs) with several Renewable Energy (RE) developers in the State, many of whom hold vacant land at or adjacent to their generating sites. 

Co-locating a Battery Energy Storage System (BESS) at such existing RE plants allows the battery to be charged directly from the co-located RE source, improving charging efficiency and round-trip economics, avoiding network charging losses, and deferring transmission/distribution augmentation, while firming up renewable supply and supporting peak management. 

Co-located BESS commissioned on or before 30 June 2028 and connected at the same substation as the RE project are also eligible, subject to conditions, for the Ministry of Power's 100% waiver of inter-State transmission (ISTS) charges where the stored energy is consumed outside the State. 

This EoI is issued in line with the APERC (Battery Energy Storage Systems) Regulations, 2025 and the objectives of the AP Integrated Clean Energy Policy, 2024 (target of 25 GWh of storage by 2029).

Through this EoI, APPCC seeks to gauge the interest, readiness and indicative commercial expectations of existing RE generators to install co-located BESS. This is a market-discovery exercise only; it does not constitute a tender, RfS or offer.

Scope and Minimum Technical Requirements:

Eligible RE Generators shall propose installation of a co-located BESS at their existing RE project site meeting the following minimum requirements: 

  1. Minimum BESS power capacity: 50% of the installed RE capacity (i.e. X MW for a project of 2X MW). 
  2. Minimum discharge duration: 4 hours at rated power (i.e. X MW / 4X MWh). 
  3. The BESS shall be charged primarily from the co-located RE source; grid drawal for charging, where permitted, shall not exceed the limit prescribed under applicable regulations. 
  4. Interconnection at the same pooling substation / bus as the existing RE plant, at the appropriate voltage level (e.g. 33 / 132 / 220 kV) as applicable to the plant. 
  5. Minimum round-trip efficiency, capacity maintenance and augmentation to sustain the contracted MWh through the engagement period. 
  6. Separate ABT-compliant metering for BESS charging and discharging, and real time data/telemetry to APSLDC/SCADA. 
  7. Compliance with CEA (Technical Standards for Connectivity) Regulations, IS/IEC standards, and applicable fire-safety and environmental norms.

What is CPH4 ?

By -
 CPH4, as presented in popular culture, particularly in the movie Lucy (2014), is portrayed as a highly potent compound that enhances brain function to extraordinary levels. In the movie, it is fictionalized as a substance produced naturally by pregnant women to help with fetal development, and when artificially consumed, it supposedly unlocks the "full potential" of the human brain, leading to superhuman abilities. Real-World Context of CPH4 In reality, CPH4 as depicted in Lucy does not exist . However, there are compounds that play critical roles in fetal development and cellular energy. The closest real-world parallel might be Guanosine-5'-Triphosphate (GTP) or Adenosine Triphosphate (ATP) : ATP is a molecule that cells use for energy, crucial for numerous bodily functions, from muscle contraction to cell division. GTP is another energy-carrying molecule involved in protein synthesis and signal transduction, essential for cell communication and metabolic processes...

Deviation Settlement Mechanism (DSM) guidelines 2024

By -
As per the latest Deviation Settlement Mechanism (DSM) guidelines from the Central Electricity Regulatory Commission (CERC), DSM charges are defined based on grid stability needs, particularly regarding frequency deviation and renewable energy dynamics. The charges vary depending on the deviation percentage from the target frequency range (49.90 Hz to 50.05 Hz), with penalties scaling for larger deviations. For renewable-rich and super renewable-rich states (based on their installed wind and solar capacity), CERC allows greater flexibility in permissible deviation limits on the demand side. This aims to balance the grid challenges posed by variable renewable generation. States with renewable capacities between 1 GW and 5 GW are considered renewable-rich, while those with over 5 GW are super renewable-rich. Stand-alone energy storage systems (ESS) are subject to similar DSM charges as general sellers, but ESS paired with renewables like wind and solar follow specific volume limits for o...

What is Kaprekar's constant ?

By -
Image
 6174 is known as Kaprekar's constant , a magical number in mathematics. The "magic" lies in a process discovered by the Indian mathematician Dattatreya Ramchandra Kaprekar in 1949. Here's how it works: The Kaprekar Routine: Take any four-digit number, using at least two different digits. (If the number has fewer than four digits, pad it with leading zeros to make it four digits). Arrange the digits in descending order and then in ascending order to get two four-digit numbers. Subtract the smaller number from the larger number. Repeat the process with the result. No matter what four-digit number you start with, after a few iterations, you'll always reach 6174 . Once you reach 6174, repeating the process will continue to yield 6174. This is why 6174 is often called a "self-repeating number" or Kaprekar's constant. Example: Start with 3524: Descending: 5432 Ascending: 2345 Subtract: 5432 - 2345 = 3087 Now repeat the process: Descending: 8730 Ascending...

Why the dislike button is removed in all the social media platforms?

By -
 The removal or absence of a dislike button on most social media platforms can be attributed to several reasons, primarily centered around user experience, mental health, and the dynamics of online interactions. Here's a detailed explanation: 1. Preventing Negativity and Harassment A dislike button could encourage negative behaviors, such as trolling or bullying. Users might use it to target individuals or content creators, leading to a toxic environment. Platforms aim to promote constructive engagement rather than actions that might demoralize users. 2. Mental Health Concerns Social media companies are increasingly aware of the impact their platforms have on mental health. Visible indicators of disapproval could harm users' self-esteem and lead to stress or anxiety, especially for younger or vulnerable audiences. 3. Focus on Constructive Feedback Platforms encourage users to give feedback in a constructive manner, such as through comments or reporting inappropriate content. A...
