Last week, Erik Lavoie, a recent intern with Guardian Media Ltd, started an investigation into the process by which the Regulated Industries Commission (RIC) recommended rate increases for the Trinidad and Tobago Electricity Commission (T&TEC).
This week, he looks at T&TEC’s generation and conversion costs.
The investigation into the rate review process for T&TEC began in January of 2024, when the Business Guardian sought to inform the public with estimates of how much residential bills would increase over a five-year period. That, of course, was if Cabinet were to implement the rates recommended by the Regulated Industries Commission (RIC) in its final determination published in October 2023.
This is not something the RIC included in its final determination. A mathematical reconstruction was conducted of the method the RIC used to allocate T&TEC’s revenue requirement among different consumer classes using T&TEC’s Cost of Service Study (COSS) of 2017. It was calculated that the median household, given the increased revenue requirement for T&TEC and the RIC’s recommendation to unwind the cross subsidy from residential consumers to industrial consumers, would face an electric bill increase of 124 per cent by 2028/2029.
In doing so, some anomalies were noted in the RIC’s allowed revenue requirements for the generation portion of Opex. The below graph shows the historical data for fuel and conversion cost faced by T&TEC, according to T&TEC themselves:
Below is a chart (made by the RIC) of the approved fuel costs:
And below is a chart (made by the RIC) of the approved conversion costs:
From 2021 to 2024 (2023 is written, but this is being treated as 2024 costs, due to delayed implementation), efficient-operation fuel costs are projected to increase from $1.08 billion in 2021 (historical) to $1.75 billion in 2024 (projected), an increase of 63 per ceny over the three-year period.
From 2021 to 2024, efficient-operation conversion costs are projected to increase from $980 million in 2021 (historical) to $1.77 billion in 2024 (projected), an increase of 80 per cent over the three-year period.
In aggregate, efficient-operation generation costs are expected to increase from $2.06 billion in 2021 to $3.52 billion in 2024, an increase of 71 per cent.
There are three things worth noting:
1) The percentage increase calculated is the efficient-operation (according to the RIC) cost of generation. What the RIC did to simulate competition in a regulated, monopolistic market and encourage efficiency is implement cost pass throughs of 95 per cent for fuel costs and 98 per cent for conversion costs (capacity cost only, rest is 100 per cent).
This means using T&TEC’s proposed amount instead of the RIC’s proposed amount for generation costs in 2024 would amount to a 77 per cent increase instead of a 71 per cent increase;
2) It does not seem like the RIC properly scrutinised the actual T&TEC estimates, and instead opted to adopt T&TEC’s projection and fit a cost pass through mechanism over it as the efficient cost;
3) The RIC did not provide a full justification for a 63 per cent increase in fuel costs and any justification 80 per cent increase in conversion costs in its final determination! All it did was include the charts with the approved amounts, which alone indicate the 71 per cent increase in generation costs.
No recognizable effort was made to explain the underlying changes to the status quo that were driving the sharp increases in conversion costs in the final determination. This would explain why only one out of the 24 stakeholders who submitted a written response on the RIC’s draft determination pointed out this anomaly. This stakeholder merely pointed out the “70 per cent” (stakeholder’s own calculation) increase in generation costs, but did not question the RIC’s assessment.
Below are images of the fuel cost and conversion cost sections of the final determination that come the closest to justifying the RIC’s approved amount:
Fuel costs
Under the terms of the Power Purchase Agreements (PPA), T&TEC has to pay for the fuel that is converted into electricity by the generators. T&TEC buys fuels from the NGC, at a pre-determined price that is influenced by the Government. The RIC has used a fuel price in keeping with T&TEC’s assumption in its business plan. (T&TEC has indicated it is based on guidance it has confirmed it has received from the Government) and an escalation factor of 3 per cent per annum in its revenue calculation
Conversion costs:
Two of the major components of T&TEC are the cost of power (conversion cost) and fuel cost, comprising 75.2 per cent of T&TEC’s total operation expenditure. COnversion and fuel costs are considered to be uncontrollable costs, that is costs over which the action of the utility have little or no effect. Hence they are treated as pass through. These costs are also subject to long-term contractual agreements (PPAs).
On the basis of its assessment of growth in demand, T&TEC submitted forecasts for conversion costs from all the generators. In the case of conventional generation, this comprises both capacity and energy payments. The generation coming from the proposed solar photovoltaic plans comprise energy paymenys on.
In the draft determination, the RIC’s view was to allow a 98 per cent pass through of capacity payments and 100 per cent pass through on the energy component of conversion costs.
The remainder goes on to discuss integration of utility scale solar in 2025.
As one can see, there is absolutely nothing the RIC says that remotely touches on justifying the RIC’s approved conversion costs, beyond stating the obvious.
With what was seen in the final determination, the Business Guardian turned to asking the RIC some questions.
The RIC was asked to provide a justification/explanation as to what factors were driving the drastic increase in fuel and conversion costs. The RIC replied with an explanation stating that the demand rebound from the COVID-19 recovery period is responsible for the increase.
This response seemed to deficient as the final determination includes historical electricity demand and the RIC’s own demand projections for each year between 2023/2024 and 2027/2028. From 2021 to 2024, electricity demand is projected to increase by 6.5 per cent.
Factoring in the 3 per cent increase per annum in fuel costs and 2 per cent increase (estimated) in the US CPI for calculating increase in conversion costs, while assuming -1 per cent per year system heat rate efficiency improvement per year (impacts fuel cost) and no changes to T&D system losses, the status quo increase in total generation costs from 2021 to 2024, given a 6.5 per cent increase in demand, should be between 8 per cent and 13 per cent. Thus, the RIC only explained up to 13 per cent out of the 71per cent increase in generation costs, leaving more than 58 per cent unexplained.
I sent a second email reiterating the question and answer in the first email, then asking the RIC to provide a different answer given that their explanation was challenged. Their response to the second email was the following:
“Thank you for your follow-up inquiry. At this time, we do not have any additional information to provide beyond what has already been shared on the matter. Please feel free to reach out again should you need anything further.”
This response was particularly concerning, as it implied that the RIC that they are not willing to justify the real reason.
Revisiting the final determination:
There was something noticed when re-reading the RIC’s final determination following its response to the newspaper’s questions.
T&TEC did not, and historically has not, reported a proper regulatory account to the RIC for the rate review process. The full text in the determination addressing this can be found in Annex I, which is at the very bottom of this document.
The RIC is trying to get T&TEC to publish the regulatory account quarterly to the RIC, which has not happened. This, of course, is something that is critically important, as it would hinder the RIC’s ability to scrutinize T&TEC’s proposal without a proper regulatory account submission from T&TEC. This is an integral step to conducting a proper and fair rate review.
Furthermore, the RIC looks to mandate the quarterly publishing of T&TEC’s regulatory account in at least one of T&T’s local newspapers.
Question and request to T&TEC:
After asking the RIC, a similar question was asked of T&TEC to the one sent to the RIC, as follows:
“If permitted, can T&TEC explain the main reason(s) why T&TEC requested such a large increase in fuel costs and conversion costs? For instance, did T&TEC’s cost structure change (ex. NGC gas price increase)? Are T&TEC’s broader financial obligations to NGC and/or IPPs, such as debt, being rolled into operational generation costs? Details would be appreciated.
“Would T&TEC be able to provide Guardian Media with a copy of certain pages/page of T&TEC’s business plan shared with the RIC that contains evidence proving T&TEC provided a written justification to the RIC regarding a 71 per cent increase in generation costs?
If T&TEC agrees to do so, we can assure T&TEC that no part of the business plan, even unredacted portions, will be quoted or shared in an article. It will be kept completely confidential. Only a mention that T&TEC provided Guardian Media evidence demonstrating T&TEC’s efforts in communicating the necessity for a 71 per cent increase in generation costs to the RIC will be mentioned in the article.”
This is the response received from T&TEC: “As you are aware, a final decision on the proposed new T&TEC rates is outstanding. To avoid the possibility of prejudicing outstanding matters, we are unable to respond to your questions at this time.”
Their response meant that I would have to search for someone with a copy of T&TEC’s Draft Business Plan.
Analyzing T&TEC’s 2021-2026 Draft Business Plan:
T&TEC’s draft business plan is not well organised. It lacks explanatory writing where necessary and has lots of charts and graphs plastered throughout the plan without clear organisation. Consequently, it feels rushed and is inadequate in several ways. Additionally, the draft business plan had two different income statement projections in the same plan for identical years, with drastically different projections ($USD ~118 million difference each year) for generation costs.
The fuel and conversion portions of T&TEC’s draft business Plan will be addressed separately:
Note that a long period of time (about two years) passed between T&TEC’s submission of the draft business plan and the RIC’s publication of the draft determination, leading to the years in question in the draft and final determination being two years ahead (2023-2028 instead of 2021-2026 in the Business Plan). By time the Cabinet decides/implements, it could be 2024-2029, or even 2025-2030.
Another clue is contained within the Fuel Costs section of the Business Plan:
“T&TEC has made strides in its attempt to liquidate its current arrears to the NGC and negotiate a long-term gas price contract.” (pg. 40).
Interestingly, this seems to suggest that T&TEC, at the moment, does not have a formal gas contract with the NGC, likely due to the inability for T&TEC to pay for the gas.
Combined with the statement in the RIC’s final determination stating that “T&TEC has indicated it [the gas price] is based on guidance it has confirmed it has received from the Government”, it can be reasonably inferred that the state-owned NGC is raising the price of gas charged to T&TEC from US$1.74/MMBTU +3 per cent per annum to US$3.00/MMBTU +3 per cent per annum.
Furthermore, it is assumed that the increase in the price of gas to be sold by NGC to T&TEC is conditional on the acceptance of a rate hike for T&TEC. Note that the previous statement is merely a reasonable assumption made; T&TEC does not provide any guidance on whether this would happen or not. It is a reasonable assumption since an increase in the price of gas to T&TEC without a rate review would just amplify T&TEC’s yearly deficits, leaving NGC with more payments from T&TEC unfulfilled and thus likely repackaged as an additional bridge loan.
Also, given that T&TEC’s gas price assumptions being derived from Government guidance is nowhere to be seen in the draft business plan, but is present in the draft and final determination, clearly suggests that either some sort of informal consultation between the RIC and T&TEC took place, and/or this statement was added in T&TEC’s submission of the final business plan to the RIC.
Therefore, while the justification is incomplete and lacking in the draft business plan, evidence suggests it is possible that T&TEC made a satisfactory justification in the final business plan for a 63 per cent increase in fuel costs.
