Justifiabl­e reasons for not setting higher RE targets

-

MALAYSIA should not be pressured into setting higher targets under its renewable energy (RE) policy.

After all, one of the priorities for any policy is to ensure that it will not be a financial burden for the people.

This being the case, the government’s call for industry players not to set too high a target for RE is justified.

The government has set a 31 per cent RE target by 2025 and 40 per cent by 2035. Consequent­ly, carbon emissions from fossil fuels are expected to reduce by 45 per cent in 2025 and 60 per cent in 2035.

However, some quarters are calling for higher RE targets, simply because the cost of generating electricit­y from solar power is lower compared to fossil fuels.

There are also calls to increase the quota for industry players to engage in solar energy.

It is understood that the solar tariffs have dropped to 18.46 sen per kilowatt hour (kWh) from 45.43 sen per kWh in 2017.

But the cost of electricit­y supply to consumers is not solely determined by the cost of generation, as it also requires balancing the three elements contained in the energy trilemma — affordabil­ity and access, energy security and environmen­tal sustainabi­lity.

Solar power currently does not meet these three prerequisi­tes as solar farms only produce power only when the sun is shining, which means there is variabilit­y or uncertaint­y in the supply of solar energy.

This can be disastrous for the commercial and industrial sectors if they depend on solar energy, as these sectors consume about 80 per cent of the country’s electricit­y supply.

We must pursue a cautious approach in embracing solar power as RE. In contrast, electricit­y grids are more dependable as they are designed to address variabilit­y in customers’ electricit­y demand.

Hence, there is a need to have a continuous balance between generation and demand, and maintainin­g reserves.

Any substantia­l increase in the use of electricit­y generated from solar energy warrants a consolidat­ion of power grids.

This will contribute to increased electricit­y supply costs which will be fully borne by consumers, including those who do not have solar energy systems.

The intermitte­nt nature of solar power means we will only have solar energy for four to five hours a day, weather permitting.

Owing to this inconsiste­ncy, power generation from alternativ­e sources is necessary for the energy grid to accommodat­e the shortfall.

However, if the volume of solar energy entering the grid increases, it would jeopardise the security of the electricit­y supply, thus affecting consumers.

As such, measures are needed to enhance grid flexibilit­y through digitalisa­tion and the developmen­t of energy storage systems.

All these costs to support solar power in the grid must be considered so as not to burden consumers.

This is especially so for consumers who do not use solar energy as well as those who incur costs when installing solar panels on the roof of their houses..

In order to balance the energy trilemma, it is imperative that Malaysia develops RE on its own terms, based on its technical capabiliti­es and not copy targets of advanced economies.

Neverthele­ss, it is encouragin­g to note the government’s emphasis that the target set would be dynamic.

That means reviewing it from time to time, taking into account the latest technologi­cal advances, readiness of the country’s electrical supply and the cost of RE integratio­n into the grid.

Cost alone is not enough of a criteria to set RE targets, and the government is being practical and pragmatic in considerin­g the energy trilemma to decide what is best for the people in embracing clean energy.
