PT PLN (Persero), Indonesia’s state-owned electricity company, has announced a major promotional campaign that’s set to bring a jolt of excitement to households across the country. From September 4 through September 17, 2025, PLN is rolling out a special discount of up to 50% for customers looking to upgrade their household electricity capacity—a move that comes as part of the company’s celebration of National Customer Day.
The campaign, aptly named “Kado Listrik Ceria (KALCER),” is designed as a gesture of appreciation for PLN’s loyal customer base. According to 55 NEWS, the program aims to make electricity upgrades more accessible, faster, and, crucially, much more affordable for families whose power needs are on the rise. The hope is that, with this discount, customers can boost their household power supply without feeling the pinch of hefty upgrade fees.
So, who exactly gets to enjoy this electrifying deal? The answer, according to both 55 NEWS and 55tv.co.id, is pretty broad. The discount is open to all low-voltage single-phase customers—regardless of their tariff category—whose current power capacity falls anywhere between 450 VA (volt-ampere) and 5,500 VA. These customers can apply to increase their supply up to a maximum of 7,700 VA. There’s just one catch: to qualify, customers must have been registered with PLN before September 1, 2024.
Adi Priyanto, PLN’s Director of Retail and Commerce, explained the company’s motivation behind the promo in a statement to the press in Jakarta. “Through the Kado Listrik Ceria (KALCER) program, PLN is committed to providing services that are easy to access, fast, and affordable. With this promo, customers can increase their power as needed without bearing the full cost,” Priyanto said, as reported by 55tv.co.id. The sentiment echoes the company’s broader push to support Indonesian households as their electricity demands grow—whether due to new appliances, expanded homes, or simply changing lifestyles.
The savings on offer are nothing to sneeze at. For instance, a customer currently on a 450 VA plan who wants to jump straight to 7,700 VA would normally face a bill of Rp7,025,250. Thanks to the KALCER promo, that same upgrade will cost just Rp3,512,625—a substantial discount that could make all the difference for families looking to future-proof their homes without blowing their budgets.
Applying for the discount is designed to be as painless as possible. PLN has moved the entire process online, making use of its popular PLN Mobile app. Customers simply need to log in, follow the step-by-step instructions, and submit their application for a power upgrade. The company has also tailored the requirements for different types of customers. Prepaid customers (those who use tokens) only need to have made at least one token purchase to qualify. Postpaid customers, on the other hand, simply need to ensure their current month’s electricity bill is paid in full. No complicated paperwork, no endless queues—just a few taps on a smartphone, and the process is underway.
PLN’s decision to tie the promo to National Customer Day is no coincidence. The company has made it clear that KALCER is as much about gratitude as it is about business. “This program is a form of PLN’s appreciation to customers in the context of National Customer Day,” Priyanto emphasized, according to 55 NEWS. It’s a nod to the millions of households that keep the lights on—literally and figuratively—for Indonesia’s largest electricity provider.
For many families, the timing couldn’t be better. As Indonesia’s economy continues to grow and more households invest in modern conveniences—from air conditioners to electric vehicles—the demand for reliable, higher-capacity electricity is only increasing. Yet, the cost of upgrading has often been a stumbling block, especially for those on fixed incomes or with other financial priorities. With this 50% discount, PLN is hoping to remove a significant barrier and encourage more households to make the leap.
It’s not just about individual savings, either. By making it easier for customers to upgrade their power supply, PLN is also aiming to support broader national goals around energy efficiency and electrification. More households with sufficient power capacity means fewer overloaded circuits, less risk of outages, and a smoother path toward adopting new, energy-intensive technologies in the future.
The promo has already generated a buzz, with both news outlets and social media users sharing tips on how to claim the discount. The process, as outlined by both 55 NEWS and 55tv.co.id, is straightforward: download the PLN Mobile app, log in, and follow the on-screen instructions. For those needing more information, PLN’s official website and call center are standing by to answer questions and provide support.
Of course, there are a few important caveats. The discount is strictly limited to the September 4–17 window, and only applies to customers who were registered before September 1, 2024. Those hoping to take advantage of the deal are being urged not to delay—there’s no word yet on whether a similar promo will be offered again in the near future.
For families who have been putting off an upgrade due to cost concerns, the message is clear: now is the time to act. “Don’t miss this golden opportunity! Immediately take advantage of PLN’s power upgrade discount promo to meet your household electricity needs more economically,” 55 NEWS urged readers in its coverage.
As Indonesia continues to modernize and electrify, programs like KALCER are likely to play an increasingly important role in bridging the gap between aspiration and affordability. PLN’s move to digitize the application process, streamline requirements, and offer meaningful discounts is a sign of a company adapting to the needs of a new generation of customers—one that values convenience, transparency, and a little help in making their homes brighter and more efficient.
With the deadline fast approaching, eligible customers are being encouraged to act quickly. For many, this could be the perfect moment to power up their homes and embrace a more comfortable, electrified future—without breaking the bank. And as National Customer Day approaches, PLN’s KALCER promo stands as a shining example of how a little appreciation can go a long way.
