Recently, a significant announcement has gone viral in the energy sector: The National Energy Administration issued a notice explicitly requiring further implementation of the "Thousands of Households Bathed in Light" initiative! Like a massive boulder dropped into a calm lake, this news instantly sent ripples across the industry, triggering strong reverberations in the photovoltaic and energy storage fields.
Great opportunities for rural energy storage
Current Status of Rural Photovoltaics
For a long time, numerous challenges exist in rural photovoltaic development. In villages with abundant solar resources, reverse power flow frequently occurs during peak generation periods. This not only leads to wasted electricity but may also trigger blackout risks when exceeding transformer capacity, severely disrupting villagers' normal power supply. Moreover, when implementing village-wide PV projects, multi-household grid connections often hit transformer capacity limits, causing equipment overloads, which hinders the large-scale development of rural photovoltaics.
Policy Direction
To tackle these long-standing bottlenecks hindering the development of rural photovoltaics, the National Energy Administration has taken decisive action.
Energy Storage System Solutions
The newly released policy can be described as a targeted remedy, designed to effectively address two major challenges through the regulatory role of energy storage systems - inadequate grid absorption capacity and transformer capacity limitations. Based on grid demand and photovoltaic generation conditions, the electricity is stored or released in a rational manner.
Energy storage system solution
PART 01
In addressing the issue of inadequate grid absorption capacity, energy storage systems can store surplus electricity during periods of excess photovoltaic power generation, thereby preventing impact to the grid caused by reverse power flow. During peak demand or insufficient PV generation, the stored energy can then be discharged to replenish the power supply of the grid, achieving "peak shaving and valley filling" of electricity loads.
PART 02
Energy storage systems can also play a crucial role in addressing transformer capacity limitations. In village-wide PV promotion projects, grid connections from multiple households can easily lead to transformer overload. By adopting a "village-wide aggregation + energy storage" model, the photovoltaic power generation of each household is first collected into the energy storage system. Then, based on the transformer's capacity and grid demand, it can deliver electricity to the grid in an orderly manner. This approach reduces the impact of single-point connections on the transformer and ensures the smooth grid integration of PV projects.
Great prospects for rural energy storage
The future looks bright and prosperous
For farmers, this represents a golden opportunity to increase income and prosper. Under the rural "PV + energy storage" model, in addition to basic power generation revenue, excess electricity fed into the grid qualifies for feed-in tariff subsidies. The energy storage arbitrage model not only transforms farmers from energy consumers to energy producers but also injects new vitality into rural economic development.
