求翻译：Furthermore, in art. 28, there is an obligation for NEC each year to calculate and plan its (on its own account) investments for the development and upgrading the grid related to the renewables projects. According to the same art. 28, NEC should include these costs in their annual investment plan. When such plan is presented to the Regulator and approved, the Regulator includes the costs of the plan in the price of the energy which NEC sells to the local distribution companies. In this way, NEC is accruing the money for the investments in the grid.是什么意思？
