To offset the variable nature of solar and wind generation, PDP 2026 will integrate utility-scale Battery Energy Storage Systems (BESS) to guarantee baseline grid stability comparable to conventional gas-fired plants.<\/p>\n
\u00a0<\/p>\n
Crucially, the blueprint formally incorporates Distributed Energy Resources (DERs)\u2014including residential solar panels, electric vehicles, and localised batteries.<\/p>\n
\u00a0<\/p>\n
These decentralised assets can be aggregated into Virtual Power Plants (VPPs) to deliver up to 14,000 MW of virtual capacity, eliminating the immediate need to construct physical base-load power stations.<\/p>\n

The ‘Cost of Inaction’ and Smart Grid Infrastructure<\/p>\n
While modernising national infrastructure requires substantial capital, TDRI’s Areeporn cautioned against focusing solely on upfront expenditure, urging decision-makers to weigh the severe “cost of inaction”.\u00a0<\/p>\n
\u00a0<\/p>\n
She warned that if Thailand delays smart grid investments while global decarbonisation pressures build, the country faces massive economic losses driven by expensive backup fossil-fuel plants, volatile fuel imports, and diminished export competitiveness.<\/p>\n
\u00a0<\/p>\n
Dr Areeporn outlined that managing a decentralised, weather-dependent grid requires a smart grid framework anchored by four essential pillars:<\/p>\n
\u00a0<\/p>\n
\u2022 Forecasting: Predicting volatile renewable generation and demand fluctuations.<\/p>\n
\u2022 Measurement: Recording real-time power generation down to localised regional levels.<\/p>\n
\u2022 Control: Actively managing and balancing electricity flows to maintain system stability.<\/p>\n
\u2022 Observation: Maintaining continuous system visibility to prevent localised grid failures.<\/p>\n
\u00a0<\/p>\n
She called for a fair pricing structure where grid modernisation costs are shared proportionally, ensuring that commercial entities benefiting most from green power contribute equitably to the physical infrastructure.<\/p>\n

Overcoming Technical Volatility and Grid ‘Invisibility’<\/p>\n
The technical urgency of upgrading grid management was reinforced by state utility operators. Jakgree Sirimaneewattana, Assistant Governor of the Electricity Generating Authority of Thailand (EGAT), explained that bi-directional power flows from residential “prosumers” are creating reverse power flows, destabilising voltage as power pushes back from distribution networks into the high-voltage transmission system.<\/p>\n
\u00a0<\/p>\n
To maintain system quality, EGAT is deploying artificial intelligence forecasting models to predict renewable output and is constructing a specialised smart control centre scheduled to open in 2028.<\/p>\n

\u00a0<\/p>\n
On the distribution front, Pongsakorn Yuthagovit, Deputy Governor of the Provincial Electricity Authority (PEA), highlighted the challenge of grid “invisibility”.<\/p>\n
\u00a0<\/p>\n
Without granular, localised data, balancing peak daytime solar generation against heavy evening EV charging becomes exceptionally difficult.<\/p>\n
\u00a0<\/p>\n
To restore network visibility, PEA is accelerating the rollout of Advanced Metering Infrastructure (AMI) and smart sensors nationwide. Both EGAT and PEA leaders concluded that flexible Time-of-Use (TOU) pricing will be vital to signal to consumers when to store energy, draw from the grid, or feed surplus power back into the network.
