Midday Off-Peak Electricity Policies Impact Profit Models, Making Energy Storage A Necessity

Over 20 provinces in China have implemented midday off-peak electricity pricing policies (for example, Hunan and Jiangsu have explicitly reduced electricity prices by 60%-70% during the peak photovoltaic power generation period (12:00 PM to 2:00 PM), with some provinces seeing off-peak prices as low as 0.12 yuan/kWh), directly undermining the profitability of photovoltaic projects.

This move has forced projects to accelerate their transition to a photovoltaic plus energy storage model, improving economic efficiency through "low-cost midday charging and evening peak discharge." The proportion of industrial and commercial distributed photovoltaic systems equipped with energy storage has increased significantly, accelerating the implementation of integrated photovoltaic storage in scenarios such as source-grid-load-storage and zero-carbon industrial parks. The surge in storage demand has become the most pressing industry hotspot of the month.

Shandong's first new energy mechanism electricity price bidding will launch in August, explicitly requiring that grid-connected electricity from general industrial and commercial distributed photovoltaic projects participate in electricity market transactions, further strengthening the rigid constraints on energy storage's regulatory capacity.

Here's a simple explanation of this news:

Chinese commercial photovoltaic companies have been feeling a bit frustrated lately. Noon to 2:00 PM is typically their peak working time, but over 20 provinces across the country have suddenly announced, "Electricity during this time will be 30% off!"

It's like when you're working overtime and your boss suddenly announces 30% overtime pay. In places like Hunan and Jiangsu, the price of photovoltaic electricity at noon has been slashed by 60%-70%, even dropping to 0.12 yuan per kilowatt-hour in some places, cheaper than mineral water.

This has left photovoltaic panel owners feeling uneasy: If they can't make money when the sun is at its hottest, do they have to wait for the moon to come out to generate electricity?

Thankfully, there are always more solutions than problems. Now, everyone is using a "power bank" with their photovoltaic panels-storing the electricity generated at noon and selling it in the evening when demand peaks. The price difference is significant. One factory in Yangzhou has profited 20% more annually by doing this. Nowadays, commercial and industrial photovoltaic projects without energy storage are embarrassed to compete with their peers.

Even more interesting is the fact that Shandong Province will introduce new "rules of the game" in August: if you want to sell photovoltaic power online, you must first prove that you have the ability to regulate it-in other words, you must bring a "power bank." This wave of changes has suddenly made energy storage a hot commodity, like a coffee shop suddenly requiring "straws with coffee," instantly transforming it from an optional accessory into a necessity.

Ultimately, while this may seem like a challenge for the photovoltaic industry, it's actually forcing everyone to upgrade. After all, sunlight waits for noon, so instead of wasting your midday electricity, it's better to find ways to conserve it. It's just a shame for those photovoltaic panels that haven't had time to install energy storage. They're probably wondering, "Why not just take a break at noon?"
