TRIS Rating assigns the company rating of B. Grimm Power PLC (BGRIM) at “A” with “stable” outlook. The rating reflects the company’s position as one of the leading private power producers in Thailand, its well-diversified portfolio of cogeneration power units under the Small Power Producer (SPP) scheme, and reliable cash flows from long-term power purchase agreements (PPAs) with the Electricity Generating Authority of Thailand (EGAT) and reputable clients. The rating also reflects BGRIM’s proven record of operating gas-fired combined cycle cogeneration units and its growth opportunities. These strengths are partially offset by a high-leveraged balance sheet during pursuing its growth strategy.
KEY RATING CONSIDERATIONS
Well-diversified portfolio
BGRIM owns and operates thirty-one power plants, in Thailand and abroad, with an installed capacity totaling 1,779 megawatts (MW). When measured in proportion to BGRIM’s ownership of the plants, or equity capacity, the total comes to 1,008 megawatts equity (MWe). No single power plant accounts for more than 10% of the total equity capacity.
Conventional power plants account for 92% of BGRIM’s total equity capacity. These 13 plants are gas-fired combined cycle cogeneration power plants located in four industrial estates and one industrial park namely Amata Nakorn (Chonburi), Amata City (Rayong), Laem Chabang, Bangkadi, and Hemaraj, plus one diesel-fired power plant in Amata City (Bien Hoa) Industrial Estate (ABIE) in Vietnam. The remaining equity capacity of 8% spreads across 15 solar power plants in Thailand and two hydro power plants in the Lao People’s Democratic Republic (Lao PDR).
EGAT is BGRIM’s largest customer. Sales to EGAT made up 52%-61% of total revenue during 2015-2017. Electricity and steam sold to industrial users accounted for 32% of revenue annually. The remainder is electricity sold to industrial users in Vietnam, the Provincial Electricity Authority (PEA), and the Electricite du Laos (EDL).
Revenue was around Bt31.5 billion in 2017, up from Bt27.7 billion in 2016. The 13% increase reflects the full-year operation of B. Grimm Power (WHA) 1 Ltd. (BPWHA1) and Amata B. Grimm Power 5 Ltd. (ABP5). Earnings before interest, tax, depreciation, and amortization (EBITDA) was around Bt8.7 billion, up from Bt7.5 billion in 2016.
Reliable cash flows from long-term PPAs
BGRIM has predictable and sustainable cash flows. Most of BGRIM’s power plants have long-term PPAs under the SPP scheme with EGAT. The term of a typical PPA with EGAT is 21-25 years. The PPAs with EGAT help mitigate the market risk since EGAT agreed to dispatch not less than 80% of the contracted capacity based on operating hours. The PPA also contains a gas price pass-through mechanism.
BGRIM also has PPAs and Steam Purchase Agreements (SPAs) with users in various industries, such as automobile, packaging, and consumer products. The PPAs and SPAs cover 5-15 years. The contracts with industrial users also specify the minimum off-take amounts. The electricity tariffs charged to the industrial users are based on the electricity tariff that the PEA charges to large general service customers. The tariff generally carries a fuel adjustment charge, or Ft charge, to reflect changes in fuel prices. BGRIM’s SPP power plants hold gas supply contracts (GSA) with PTT PLC (PTT) for 21-25 years. The terms of the GSAs usually match the terms of the PPAs with EGAT.
BGRIM’s solar power plants have a total equity capacity of 59 MWe. These plants have a 25-year PPA with the PEA under the Very Small Power Plant (VSPP) scheme. The PPAs carry a Feed-in Tariff (FiT) of Bt5.66 per kilowatt-hour (kWh). The two hydro power plants, located in Lao PDR, with 14 MWe of capacity, supply electricity to EDL under a 25-year PPA. The PPA for each of the hydro power plant has a flat tariff of US$0.065 per kWh.
Proven track record of power plant operation
BGRIM’s cogeneration plants have high availability factors (AF) and low numbers of unplanned outages. Most of BGRIM’s power plants employ proven technology from reputable suppliers, such as Siemens and GE. The plant heat rates met the criteria specified in the PPAs. During the past three years, the actual AF of the cogeneration power plants ranged from 90%-99%, better than the PPA targets. The heat rate (HR) of each plant was also better than the heat rate specified in the PPAs. These achievements demonstrate BGRIM’s competence in developing and operating gas-fired combined cycle cogeneration power plants.
Potential growth as BGRIM expands
At the end of February 2018, BGRIM’s total generating portfolio was 1,779 MW. Total installed capacity will rise to 2,163 MW or 1,314 MWe by 2020. EBITDA is forecast to reach Bt12 billion within the next three years once the new plants reach their commercial operations dates (COD) as planned.
Highly-leveraged balance sheet
BGRIM has high leverage. At the end of 2017, total debt was worth Bt57.9 billion, including financial obligation relating to Amata B. Grimm Power Power Plant Infrastructure Fund (ABPIF). The total debt to capitalization ratio was 69%. Given capital expenditure of Bt8.8-Bt11.2 billion per year during 2018 to 2020, the debt to capitalization ratio will remain high at 65%-67% during the next three years. However, total debt to EBITDA in 2019-2020 will likely to improve to 5 times, from 6.7 times in 2017. BGRIM’s liquidity is strong. Cash on hand was Bt18.2 billion as of December 2017. Debt repayments will run at Bt4.3-Bt5.7 billion per annum over the next three years.
RATING OUTLOOK
The “stable” outlook reflects the expectations that the power plant operations will stay smooth as planned, the new projects will boost EBITDA, and the capital structure is forecast to stay steady.
RATING SENSITIVITIES
A rating upgrade could occur if BGRIM’s financial profile is better than expectation. The rating downside case may occur if there is a significant drop in performance at the power plants or if the capital structure weakens significantly due to large-scale debt-funded investments.
