A cooperation page prints a 9,030 kW battery near Koprivnica and a 750 kW box in Zelina - the flexibility fee is blank, and the fair note describes three ways to run the box
Jutarnji list on 27 October 2026, in a page marked as made with Enna Group, prints a 9,030 kW / 33,866 kWh battery near Koprivnica and a 750 kW / 1,566 kWh battery in Sveti Ivan Zelina. ENNA Next's own page of 10 June says the Zelina box stores power from an integrated solar plant and does not print that plant's kilowatts. ENNA Next's page of 30 October, from a Zagreb fair, describes day-ahead use, shifting a producer's power, and a standalone box that charges from the grid. The portfolio line is 30 kW to 40 MW. No fee is printed.
A workplace with solar makes the most power at noon. A battery can hold some of that noon for a later hour. It can also fill from the grid when the grid price is low. The pages this week print box sizes and three ways to run a box. They do not print a fee.
On 27 October 2026 Jutarnji list published a page it marks as content made in cooperation with Enna Group. The page says ENNA Next has installed a battery of 9,030 kW and 33,866 kWh near Koprivnica, and has switched on a battery of 750 kW and 1,566 kWh in Sveti Ivan Zelina, connected to an energy-management system. It names Marijeta Majer, director of energy projects at ENNA Next. She says the value of a battery depends on the business, the shape of its consumption, solar production, peak loads, energy prices, and how the box is run. The page prints no euro figure for either site, no customer name, and no solar kilowatts beside the Koprivnica box. "Near Koprivnica" is the location line. The page does not say the box sits on a factory meter.
Hours, from the sizes the cooperation page prints. 33,866 kilowatt-hours divided by 9,030 kilowatts is about 3.75 hours at full power. 1,566 kilowatt-hours divided by 750 kilowatts is about 2.09 hours. The page does not print the hours. A kilowatt is the width of the tap. A kilowatt-hour is the size of the tank. 9,030 kW is 9.03 MW. The page prints kilowatts.
Zelina, on the company's own page. On 10 June 2026 ENNA Next said it had commissioned the Sveti Ivan Zelina battery, 750 kW and 1,566 kWh, storing energy from an integrated solar plant and lining the battery up with that plant's output, the user's consumption, and market signals. The solar plant's kilowatts are not on that page. Koprivnica is not on that page. The customer is not named. The June page and the October cooperation page agree on 750 kW and 1,566 kWh. Only the June page says the Zelina box stores solar.
The fair note, dated 30 October 2026. ENNA Next says Dario Antolović, director of integrated energy services, spoke on 28 and 29 October at the Green Energy Fair in Arena Zagreb, on a panel about the new rules of the Croatian electricity market. He describes three shapes. One follows the day-ahead market: watch the price, then store, export, or use the power on site. A second is for producers who move a share of their power out of the hours with the worst price and into the hours with the best price. A third is a standalone battery that draws energy from the grid and stores it. He says the company is grouping smaller plants, and that the portfolio runs from 30 kW to 40 MW. Partners receive a payment for that flexibility. The payment is not printed. 30 kW to 40 MW is the range of plants in the portfolio. It is the company's description of many sites added together. It is a different number from 9,030 kW at one place near Koprivnica. The note mentions negative prices and does not print a cent, or a euro, per kilowatt-hour.
Fifteen minutes. The cooperation page says the management system works out charge and discharge every 15 minutes, and calls that 35,000 decisions a year. A 15-minute step comes 96 times in a day. The page's 35,000 is the figure it prints. It is not a measured saving, and it is not a euro figure.
Same fair, a different company, already on this desk. The Cemex note is from the same Zagreb fair. Cemex named solar on its own sites and did not name a battery. The farm and food-plant grant is a separate public pot, with applications from 9 November. The ENNA pages are a seller's description of boxes and of ways to run them. They are not that grant.
Analogy: two tanks on the cooperation page, one of them repeated on the company's June page, and a fee that is not on any of the three pages. The fair note says a box can follow the noon sun, follow the price, or fill from the grid. Which of those three the Koprivnica tank does is not written down.
Good: Two pages inside this week, named kilowatts and kilowatt-hours, a company page that ties the Zelina box to a solar plant, and a plain list of three operating shapes.
Bad: The 27 October page is marked as cooperation with Enna Group. Customer names are blank. Solar kilowatts beside Koprivnica are blank. Solar kilowatts at Zelina are blank. The flexibility fee is blank. The negative-price level is blank. 30 kW to 40 MW is a portfolio range. The Koprivnica meter is not named.
Ugly: Reading 9,030 kW as 9,030 kWh. Treating the cooperation page as an independent meter reading. Treating 30 kW to 40 MW as one battery. Putting a fee on an invoice the page does not print. Treating "near Koprivnica" as a named factory. Adding solar kilowatts the Zelina page does not print.
Soft next step: set 33,866 kWh and 1,566 kWh beside the customer and the fee, and leave both blank until a page prints them.

Primary for the cooperation label, the 9,030 kW / 33,866 kWh battery near Koprivnica, the 750 kW / 1,566 kWh battery in Sveti Ivan Zelina on that page, the energy-management system, Marijeta Majer's list of what the value depends on, the absence of a euro figure, a customer name and solar kilowatts beside Koprivnica, and the line that the system recalculates every 15 minutes, called 35,000 decisions a year. 33,866 kWh divided by 9,030 kW, and 1,566 kWh divided by 750 kW, are our description of the hours. The page does not print those hours. A 15-minute step 96 times a day is our count. The page prints 35,000. ENNA Next, 10 Jun 2026 - Sveti Ivan Zelina battery. Primary for the company's own 750 kW and 1,566 kWh figures, storage of energy from an integrated solar plant, coordination with the user's consumption and market signals, and the absence of the solar plant's kilowatts, of Koprivnica, and of a customer name. ENNA Next, 30 Oct 2026 - Green Energy Fair panel. Primary for Dario Antolović's remarks from the 28 and 29 October fair at Arena Zagreb, the day-ahead shape, the shift of a producer's power from weaker-priced hours to stronger-priced hours, the standalone battery that charges from the grid, the portfolio from 30 kW to 40 MW, a flexibility payment with no amount printed, and negative prices with no euro-per-kilowatt-hour printed.
