Economics
Cost Competitiveness
Solar is among the lowest-cost sources of new electricity generation. Stationary battery pack prices fell to about USD 70/kWh in 2025 (BNEF), though full turnkey systems cost more (see the calculator below).

Phase 1
Development
Land acquisition and lease negotiation (typically 25+ year terms). Environmental Impact Assessment (EIA) and social impact studies. Grid connection study with TNB — evaluating 33 kV, 132 kV, or 275 kV interconnection options.
Permitting through SEDA, Energy Commission, DOE, and local authorities. Preliminary system design, yield simulation (PVsyst), and project financial modelling including the GITA tax allowance (60% of qualifying solar CAPEX; 100% for BESS; via MGTC, for CAPEX incurred by 31 Dec 2026).
account_balance
Phase 2
Financial Close
PPA negotiation and execution (typically 21 years for LSS). Project finance structuring with commercial banks, DFIs, or infrastructure funds — typical debt-equity 70:30 to 80:20.
Comprehensive insurance coverage: construction all-risks (CAR), business interruption, third-party liability. EPC contract with performance guarantees, liquidated damages, and defect liability periods. Independent engineer (IE) review for lender due diligence.
construction
Phase 3
EPC Delivery
Procurement of BNEF Tier-1 modules (JA Solar, Canadian Solar — 22%+ cell efficiency), string or central inverters (Huawei, Sungrow — 98.5%+ conversion), and balance-of-system components. Civil works: land clearing, access roads, piling (driven or screw), and mounting structures.
Electrical: DC string wiring, AC collection cables, step-up transformers, switchgear, and protection systems. Grid interconnection: TNB coordination, relay testing, and synchronisation. Performance testing: PR verification, I-V curve testing, thermography, and COD certification.
monitoring
Phase 4
Operations & Asset Management
24/7 SCADA-integrated monitoring from ERS Energy’s Network Operations Centre. Preventive maintenance: scheduled panel cleaning, inverter servicing, vegetation management, and tracker lubrication. Corrective maintenance: fault diagnostics, component replacement, and warranty claims management.
Performance optimisation: degradation tracking (typical 0.5%/year for Tier-1 modules), soiling analysis, and re-stringing. Quarterly reporting to investors and lenders. Lifecycle asset management including insurance renewal, refinancing support, and end-of-life planning.

Energy Value
One battery, one daily cycle.
This estimator shows the illustrative annual energy value of one daily charge-discharge cycle for a grid-scale BESS, net of operating cost, next to a reference capex. Utility BESS in Malaysia is procured through contracted programmes (e.g. MyBeST); returns depend on contract terms, so no payback is shown. Duration sets the capacity in MWh.

Step Two
Your illustrative energy value.
The bar shows the annual value of shifting energy through one cycle a day. The totals show the value net of operating cost and a reference capex; no payback or capacity payment is shown.

Step Three
How others use this.
Two short walkthroughs from project developers and IPPs evaluating BESS investments.
Scenario 01
“We need to size a BESS to pair with our LSS project.”
Set system power to 20 MW and duration to 4 hours, a common pairing for a 50 MW solar farm. The estimator shows the 80 MWh capacity earning an illustrative energy value, with the reference capex alongside.
Result: 20 MW / 4-hour, illustrative annual energy value RM 3.2M gross (RM 2.6M net of opex), reference capex RM 38.2M
Scenario 02
“We’re evaluating a standalone grid services contract.”
Set system power to 10 MW and duration to 2 hours. This is a quarter of the 80 MWh capacity above, so both the energy value and the reference capex fall in proportion.
Result: 10 MW / 2-hour, illustrative annual energy value RM 0.8M gross (RM 0.7M net of opex), reference capex RM 9.5M
